Powerful snowstorm snarls traffic across the West

By FELICIA FONSECA, Associated Press Writer Felicia Fonseca, Associated Press Writer – 1 hr 3 mins ago

FLAGSTAFF, Ariz. – A large and powerful storm howled across the West with snow and strong winds Monday, snarling traffic, closing schools and threatening to spawn mudslides in wildfire-devastated Southern California.

Virtually the entire region was suffering — from subzero wind chills in Washington state to heavy snow that closed schools and government offices in Reno, Nev., and left big rigs jackknifed across highways in several states. Blizzard warnings were in effect for northern Arizona and parts of Colorado, with forecasters predicting up to 2 feet of snow around Flagstaff.

The National Weather Service said the upper elevations of the Sierra mountains could get up to 3 feet of snow, with up to 4 feet forecast for the mountains of southern Utah. Even the hills east of San Francisco Bay received a rare dusting overnight, and snow was predicted for Fresno and other communities in California's Central Valley.

Bad weather stretched far to the east as well. The first snow of the season for much of Indiana tangled traffic and delayed schools. Crashes left one person dead.

Reno schools closed, and many state government workers were told to stay home. Chains or snow tires were required across the region. Several flights into and out of Reno-Tahoe International Airport were delayed or canceled.

"Motorists are going to have to chain up," Trooper Chuck Allen with the Nevada Highway Patrol said. "Otherwise, we end up with a parking lot."

The storm was blamed for dozens of accidents and road closures in the Flagstaff area, including a small stretch of Interstate 17 near a scenic overlook where a UPS truck lost its trailer and slammed into a barrier wall.

Deputy City Manager Jim Wine said snowfall is pretty routine for a city that sits at an elevation of nearly 7,000 feet. But winds of 30 mph with gusts of up to 50 mph are a concern because they could cause power outages and whiteout driving conditions, he said. The city school district let students out early Monday and canceled classes Tuesday. Northern Arizona University also released students and staff early Monday, in the midst of final exams.

Arizona Department of Transportation spokesman Rod Wigman vowed to keep northern Arizona roads plowed despite a $100 million budget deficit, but advised people to stay home if possible as the brunt of the storm sweeps through in the afternoon and evening.

"When the sun goes down, people need to go home," Wigman said.

Southern California was largely escaping the snow, but heavy rain — up to 4 inches was forecast in some areas — sparked concerns of mudslides. The foothill areas below the wildfire-scarred Angeles National Forest were barricaded with sandbags and concrete barriers, some decorated with Christmas garlands. Several roads in the San Gabriel Mountains, a few miles northeast of Los Angeles, were closed.

Nine canyon homes were evacuated Monday before being allowed to go home several hours later as the rain shifted south. Still, residents of foothill towns such as La Canada Flintridge were urged to be ready to evacuate at a moment's notice.

"People are nervous," homeowner Gary Stibal said as he kept watch on the burned mountain slope that rises sharply from his backyard. His car was packed and, like others in the neighborhood, was parked in the driveway facing toward the street for a quick getaway.

In San Diego, the National Weather Service issued a warning of high winds as the storm front approached. Gust of up to 60 mph were forecast, especially along the coast, foothills and deserts.

Two more storms, this time from the tropical Pacific, were expected to arrive on Thursday and Saturday.

One of those storms was churning waves up to 50 feet high off Hawaii's beaches, drawing hundreds of people to Oahu's North Shore.

Iowa, Minnesota, Wisconsin and Illinois are bracing for the prospect of more than a foot of snow, high winds and blizzard conditions Tuesday and Wednesday.

"The storm system is really strengthening as it goes, and that's usually a recipe for some heavy snowfall and a lot of wind, and that's what we're watching for," said Mike Welvaert of the National Weather Service in La Crosse, Wis.

Todd Heitkamp of the National Weather Service says the storm also was expected to hit hard in Nebraska, which already reported several inches of snow by midday Monday. In New Mexico, where one person was killed in a traffic accident blamed on slick conditions, officials told snow-clearing crews to be prepared for 12-hour shifts as the storm swept south and east.


If I'm not mistaken, this is a little freakish for this time of year.

Partial Lunar Eclipse and Blue Moon New Year's Eve
         
Mon Dec 28, 4:45 pm ET
Eclipses of the moon occur twice a year, on average. Each eclipse is visible only on the half of the Earth turned towards the moon at the time the Earth's shadow falls on the moon.

There will be a partial eclipse of the moon on New Year's Eve, Dec. 31. Because of its timing, it will not be visible in North and South America, but will be visible over most of Europe, Africa, and Asia.

The event will also mark the second full moon of the month in North America, thereby garnering the title of "blue moon." Unless unusual atmospheric circumstances come into play — such as widespread dust from a volcano — the moon will not be blue, however.

Since it is a partial eclipse, the moon will just brush past the darkest part of the Earth's shadow, never becoming totally immersed. It will, however, be deep enough into the shadow that shading and reddish color should be visible.

Even though the eclipse isn't visible for most of us in North America, it's still possible to enjoy this event through astronomy simulation software like Starry Night. An armchair skywatcher can use this software to view the eclipse from any point on Earth.

Here's how the eclipse will play out (these times will be the same for most of western Europe and central Africa):

As the sun sets in the southwest, the full moon rises in the northeast. At 6:17 p.m. local time Friday the moon begins to enter the Earth's shadow, though it is undetectable at first. At  7:52, the moon enters the darkest part of the Earth's shadow, called the umbra. Maximum eclipse is at 8:23, and the moon leaves the umbra at 8:53. The last traces of the shadow are gone by 10:28.

Observers in other parts of the Old World will have to make adjustments for their local time zones. Australians may catch a glimpse of the eclipse just before moonset at dawn on Jan. 1. Again, the eclipse is not visible from the Americas.

I missed a few big events ... Tonight, this one caught my eye.

Haiti hit by largest earthquake in over 200 years

PORT-AU-PRINCE, Haiti – The strongest earthquake in more than 200 years rocked Haiti on Tuesday, collapsing a hospital where people screamed for help and heavily damaging the National Palace, U.N. peacekeeper headquarters and other buildings. U.S. officials reported bodies in the streets and an aid official described "total disaster and chaos."

United Nations officials said a large number of U.N. personnel were unaccounted for.

Communications were widely disrupted, making it impossible to get a full picture of damage as powerful aftershocks shook a desperately poor country where many buildings are flimsy. Electricity was out in some places.

Karel Zelenka, a Catholic Relief Services representative in Port-au-Prince, told U.S. colleagues before phone service failed that "there must be thousands of people dead," according to a spokeswoman for the aid group, Sara Fajardo.

"He reported that it was just total disaster and chaos, that there were clouds of dust surrounding Port-au-Prince," Fajardo said from the group's offices in Maryland.

State Department spokesman P.J. Crowley said in Washington that embassy personnel were "literally in the dark" after power failed.

"They reported structures down. They reported a lot of walls down. They did see a number of bodies in the street and on the sidewalk that had been hit by debris. So clearly, there's going to be serious loss of life in this," he said.

Alain Le Roy, the U.N. peacekeeping chief in New York, said late Tuesday that the headquarters of the 9,000-member Haiti peacekeeping mission and other U.N. installations were seriously damaged.

"Contacts with the U.N. on the ground have been severely hampered," Le Roy said in a statement, adding: "For the moment, a large number of personnel remain unaccounted for."

Felix Augustin, Haiti's consul general in New York, said a portion of the National Palace had disintegrated.

"Buildings collapsed all over the place," he said. "We have lives that are destroyed. ... It will take at least two or three days for people to know what's going on."

An Associated Press videographer saw the wrecked hospital in Petionville, a hillside Port-au-Prince district that is home to many diplomats and wealthy Haitians, as well as many poor people. Elsewhere in the capital, a U.S. government official reported seeing houses that had tumbled into a ravine.

Kenson Calixte of Boston spoke to an uncle and cousin in Port-au-Prince shortly after the earthquake by phone. He could hear screaming in the background as his relatives described the frantic scene in the streets. His uncle told him that a small hotel near their home had collapsed, with people inside.

"They told me it was total chaos, a lot of devastation," he said. More than four hours later, he still was not able to get them back on the phone for an update.

Haiti's ambassador to the U.S., Raymond Joseph, said from his Washington office that he spoke to President Rene Preval's chief of staff, Fritz Longchamp, just after the quake hit. He said Longchamp told him that "buildings were crumbling right and left" near the national palace. He too had not been able to get through by phone to Haiti since.

With phones down, some of the only communication came from social media such as Twitter. Richard Morse, a well-known musician who manages the famed Olafson Hotel, kept up a stream of dispatches on the aftershocks and damage reports. The news, based mostly on second-hand reports and photos, was disturbing, with people screaming in fear and roads blocked with debris. Belair, a slum even in the best of times, was said to be "a broken mess."

The earthquake had a preliminary magnitude of 7.0 and was centered about 10 miles (15 kilometers) west of Port-au-Prince at a depth of 5 miles (8 kilometers), the U.S. Geological Survey said. USGS geophysicist Kristin Marano called it the strongest earthquake since 1770 in what is now Haiti. In 1946, a magnitude-8.1 quake struck the Dominican Republic and also shook Haiti, producing a tsunami that killed 1,790 people.

The temblor appeared to have occurred along a strike-slip fault, where one side of a vertical fault slips horizontally past the other, said earthquake expert Tom Jordan at the University of Southern California. The earthquake's size and proximity to populated Port-au-Prince likely caused widespread casualties and structural damage, he said.

"It's going to be a real killer," he said. "Whenever something like this happens, you just hope for the best."

Most of Haiti's 9 million people are desperately poor, and after years of political instability the country has no real construction standards. In November 2008, following the collapse of a school in Petionville, the mayor of Port-au-Prince estimated about 60 percent of the buildings were shoddily built and unsafe in normal circumstances.

Tuesday's quake was felt in the Dominican Republic, which shares a border with Haiti on the island of Hispaniola, and some panicked residents in the capital of Santo Domingo fled from their shaking homes. But no major damage was reported there.

In eastern Cuba, houses shook but there were also no reports of significant damage.

"We felt it very strongly and I would say for a long time. We had time to evacuate," said Monsignor Dionisio Garcia, archbishop of Santiago.

The few reports emerging from Haiti made clear the country had suffered extensive damage.

"Everybody is just totally, totally freaked out and shaken," said Henry Bahn, a U.S. Department of Agriculture official visiting Port-au-Prince. "The sky is just gray with dust."

Bahn said he was walking to his hotel room when the ground began to shake.

"I just held on and bounced across the wall," he said. "I just hear a tremendous amount of noise and shouting and screaming in the distance."

Bahn said there were rocks strewn about and he saw a ravine where several homes had stood: "It's just full of collapsed walls and rubble and barbed wire."

In the community of Thomassin, just outside Port-au-Prince, Alain Denis said neighbors told him the only road to the capital had been cut but that phones were all dead so it was hard to determine the extent of the damage.

"At this point, everything is a rumor," he said. "It's dark. It's nighttime."

Former President Bill Clinton, the U.N.'s special envoy for Haiti, issued a statement saying his office would do whatever he could to help the nation recover and rebuild.

"My thoughts and prayers are with the people of Haiti," he said.

President Barack Obama ordered U.S. officials to start preparing in case humanitarian assistance was needed.

Venezuelan Foreign Minister Nicolas Maduro said his government planned to send a military aircraft carrying canned foods, medicine and drinking water and also would dispatch a team of 50 rescue workers

Haitian musician Wyclef Jean urged his fans to donate to earthquake relief efforts, saying he had received text messages from his homeland reporting that many people had died.

"We must think ahead for the aftershock, the people will need food, medicine, shelter, etc.," Jean said on his Web site.

Brazil's government was trying to re-establish communications with its embassy and military personnel in Haiti late Tuesday, according to the G1 Web site of Globo TV. Brazil leads a 9,000-member U.N. peacekeeping force there.

Felix Augustin, Haiti's consul general in New York, said he was concerned about everyone in Haiti, including his relatives.

"Communication is absolutely impossible," he said. "I've been trying to call my ministry and I cannot get through. ... It's mind-boggling."

The top 20 earthquakes in previous week (severity-wise).

Interesting map. You can see on it that the Pacific gets most of the action.

Arctic Shift Brought This Winter's Chill for N. Hemisphere

Since the 1970's, the Arctic Oscillation has tended to stay in the phase that kept much of N. America and Europe in warmer temperatures than normal ... until now. A rare disruption of the Northern Hemisphere circulation since mid-December dislodged almost all of the frigid air around the Arctic, sending it thousands of miles to the south.
 
The surge chilled parts of Asia, Europe and North America with some of the most severe winter conditions in decades.

The Arctic Oscillation also caused temperatures at high latitudes around the North Pole to shoot up to levels much warmer than normal, equalizing the atmospheric heat balance.

The U.S. Center for Atmospheric Research points out that such hemispheric chills have become infrequent since 1990. And it says this winter’s cold is in bitter contrast to the above-normal weather in Europe and North America during November.

But in a possible sign that the overall global warming is not over despite the temporary northern chill, Australia’s second-largest city suffered through its hottest overnight summer weather on record.

Melbourne’s air temperature remained above 90 degrees Fahrenheit all night on the morning of Jan. 12.

I wonder what caused this disruption. The rupture in the ozone layer?
Is this how global warming kicks in a "Little Ice Age"?

USGS reports 8.8-magnitude earthquake hits Chile
           
10 mins ago
SANTIAGO, Chile – A massive 8.8-magnitude earthquake capable of tremendous damage struck central Chile early Saturday, shaking the capital for a minute and half and setting off a tsunami. Buildings collapsed and phone lines and electricity were down, making the extent of the damage difficult to determine.

The quake hit 200 miles (325 kilometers) southwest of the capital, Santiago, and at a depth of 22 miles (35 kilometers) at 3:34 a.m. (0634 GMT; 1:34 a.m. EST), the U.S. Geological Survey reported. Its epicenter was just 70 miles (115 kilometers) from Concepcion, Chile's second-largest city, where more than 200,000 people live along the Bio Bio river, and 60 miles from the ski town of Chillan, a gateway to Andean ski resorts that was destroyed in a 1939 earthquake.

Buildings shook and collapsed in Santiago. With phone lines down, confirmation of damage was difficult elsewhere, especially further south toward the epicenter. The quake was felt in Argentina as well.

The Pacific Tsunami Warning Center issued a warning for Chile and Peru, and a less-urgent tsunami watch for Ecuador, Colombia, Panama, Costa Rica and Antarctica.

"Sea level readings indicate a tsunami was generated. It may have been destructive along coasts near the earthquake epicenter and could also be a threat to more distant coasts," the center said.

The U.S. west coast tsunami warning center said it did not expect a tsunami along the west of the U.S. or Canada but was continuing to monitor the situation.

The largest earthquake ever recorded struck the same area of Chile on May 22, 1960. The magnitude-9.5 quake killed 1,655 people and left 2 million homeless. The tsunami that it caused killed people in Hawaii, Japan and the Philippines and caused damage to the west coast of the United States.

TALCA, Chile – One of the strongest earthquakes ever recorded struck Chile on Saturday, toppling homes, collapsing bridges and plunging trucks into the fractured earth. A tsunami set off by the magnitude-8.8 quake threatened every nation around the Pacific Ocean — roughly a quarter of the globe.

Chileans near the epicenter were tossed about as if shaken by a giant.

It was the strongest earthquake to hit Chile in 50 years. President-elect Sebastian Pinera said more than 120 people died, a number that was rising quickly.

The quake shook buildings in Argentina's capital of Buenos Aires, and was felt as far away as Sao Paulo in Brazil — 1,800 miles (2,900 kilometers) to the east.

In Talca, just 65 miles (105 kilometers) from the epicenter, furniture toppled as the earth shook for more than a minute in something akin to major airplane turbulence. The historic center of town largely collapsed, but most of the buildings of adobe mud and straw were businesses that were not inhabited during the 3:34 a.m. (1:34 a.m. EST, 0634 GMT) quake.

Neighbors pulled at least five people from the rubble while emergency workers, themselves disoriented, asked for information from reporters.

Collapsed roads and bridges complicated north-south travel in the narrow Andean nation. Electricity, water and phone lines were cut to many areas — meaning there was no word of death or damage from many outlying areas.

In the Chilean capital of Santiago, 200 miles (325 kilometers) northeast of the epicenter, a car dangled from a collapsed overpass, the national Fine Arts Museum was badly damaged and an apartment building's two-story parking lot pancaked, smashing about 50 cars whose alarms rang incessantly.

The jolt set off a tsunami that raced across the Pacific, setting off alarm sirens in Hawaii, Polynesia and Tonga. Tahitian officials banned all traffic on roads less than 1,600 feet (500 meters) from the sea and people in several low-lying island nations were urged to find higher ground.

Hawaii could face its largest waves since 1964 starting at 11:19 a.m. (4:19 p.m. EST, 2119 GMT), according to Charles McCreery, director of the Pacific Tsunami Warning Center. Officials evacuated people and boats near the water and closed shore-side Hilo International Airport.

Experts said tsunami waves were likely to hit Asian, Australian and New Zealand shores within 24 hours of the earthquake. The U.S. West Coast and Alaska, too, were threatened. In all, 53 nations and territories were subject to tsunami warnings.

Waves 6 feet (1.8 meter) above normal hit Talcahuano near Concepcion 23 minutes after the quake, and President Michelle Bachelet said a huge wave swept into a populated area in the Robinson Crusoe Islands, 410 miles (660 kilometers) off the Chilean coast.

Bachelet said she had no information on the number of people injured in the quake. She declared a "state of catastrophe" in central Chile but said the government has not asked for assistance from other countries.

"The system is functioning. People should remain calm. We're doing everything we can with all the forces we have," she said.

Powerful aftershocks rattled Chile's coast — 41 of them magnitude 5 or greater — in the 10 hours after the quake. Six were sizable quakes in their own right, magnitude 6 or greater.

In Santiago, modern buildings are built to withstand earthquakes, but many older ones were heavily damaged, including the Nuestra Senora de la Providencia church, whose bell tower collapsed. A bridge just outside the capital also collapsed, and at least one car flipped upside down. Several hospitals were evacuated due to earthquake damage, Bachelet said.

Santiago's airport will remain closed for at least 24 hours after the passenger terminal suffered major damage, airport director Eduardo del Canto told Chilean television. TV images showed smashed windows, partially collapsed ceilings and pedestrian walkways destroyed.

Santiago's subway was shut as well and hundreds of buses were trapped at a terminal by a damaged bridge, Transportation and Telecommunications Minister said. He urged Chileans to make phone calls or travel only when absolutely necessary.

In Concepcion, Chile's second-largest city and only 70 miles (115 kilometers) from the epicenter, nurses and residents pushed the injured through the streets on stretchers. Others walked around in a daze wrapped in blankets, some carrying infants in their arms. A 15-story building collapsed, leaving only a few floors intact.

"I was on the 8th floor and all of a sudden I was down here," said Fernando Abarzua, marveling that he escaped with no major injuries. He said a relative was still trapped in the rubble six hours after the quake, "but he keeps shouting, saying he's OK."

Marco Vidal, a program director for Grand Circle Travel who was traveling with a group of 34 Americans, was on the 19th floor of the Crown Plaza Santiago hotel when the quake struck.

"All the things start to fall. The lamps, everything, was going on the floor," he said. "I felt terrified."

Cynthia Iocono, from Linwood, Pennsylvania, said she first thought the quake was a train.

"But then I thought, `Oh, there's no train here.' And then the lamps flew off the dresser and my TV flew off onto the floor and crashed."

The quake struck after concert-goers had left South America's leading music festival in the coastal city of Vina del Mar, where organizers canceled performances on Saturday, the final night of the festival. But it caught partiers leaving a disco.

"It was very bad. People were screaming. Some people were running, others appeared paralyzed. I was one of them," Julio Alvarez told Radio Cooperativa.

The largest earthquake ever recorded struck the same area of Chile on May 22, 1960. The magnitude-9.5 quake killed 1,655 people and left 2 million homeless. The tsunami that it caused killed people in Hawaii, Japan and the Philippines and caused damage to the west coast of the United States.

Saturday's quake matched a 1906 temblor off the Ecuadorean coast as the seventh-strongest ever recorded in the world.

(CNN) -- Sirens sounded early Saturday morning across Hawaii, warning people of a possible tsunami and telling people to in coastal areas to evacuate.

The sirens sounded at 6 a.m. local time (11 a.m. ET/1600 GMT) to warn of a potential tsunami triggered by a 8.8 earthquake in Chile.

The siren systems in each county are sounding to "to alert residents and visitors to evacuate coastal areas," Hawaii's Civil Defense Division said in a statement.

"Residents will be advised by their respective country civil defense or emergency management agencies to evacuate coastal areas."

The earliest estimated arrival for a wave that could affect Hawaii is 11:05 a.m. local time (4:05 p.m. ET/2105 GMT), the Pacific Tsunami Warning Center said.

Pacific Tsunami Warning Center Director Charles McCreery said Hawaii would see some effect from the earthquake.

"We believe it will be a threat here in Hawaii, that's why we initiated a warning, not only for a Hawaii, but for the entire Pacific," McCreery said.

Asked by CNN affiliate KHON whether it was possible Hawaii wouldn't see any effect from the earthquake, McCreery said, "No, I wouldn't say that's possible at all. I think there's no chance we'll see no effect from this event.

"So people need to take this very seriously."

But he added, "We're not expecting this to be a worst-case scenario, but we are expecting ... dangerous waves coming on shore, and people need to take it very seriously."

Speaking of the evacuations, Shelly Ichishita, spokeswoman for the Civil Defense Division, said people in the evacuation zones -- basically coastal areas -- were "asked to go inland," she said. "We do not have evacuation shelters open."

John Cummings, Oahu Emergency Management Department spokesman, told The Honolulu Advertiser that "If you live anywhere in the evacuation zone, you have to evacuate.

"This is a serious event. We're going to treat this as a destructive-type tsunami."

The state's two U.S. senators, Daniel K. Inouye and Daniel K. Akaka, urged Hawaii residents to remain calm.

"If you live in an evacuation zone I urge you to gather your family and please leave the area," Inouye said.

"It is important to remain calm, listen to the news, and follow the instructions being issued by state and county civil defense officials."

Earlier Saturday, people rushed to supermarkets to stock up on food, water and other supplies.

"We got lots of water, we got our batteries, we got toilet paper," one woman told KITV, while she stood in a line with other shoppers and their carts stuffed with supplies.

Asked if she was scared, another shopper said, "Very, very. We're from Georgia, so ..."

Businesses in the area said they will be closed all day Saturday, the affiliate reported.

Several tsunami waves have come ashore along the Chilean coast after the earthquake, which killed at least 122 people, U.S. Geological Survey geophysicist Victor Sardina told CNN.

He said the largest was recorded at 9 feet near the quake's epicenter. Another wave, 7.7 feet hit the Chilean town of Talcahuano, according to Eric Lau of the Pacific Tsunami Warning Center.

Video from the town showed one car sitting in a large expanse of water.

McCreery said the first tsunami wave would sweep across Hawaii in about 30 minutes.

"And then the hazard will go on for many hours, because these waves, they get reflected off the islands, they wrap around the islands, and it becomes a very complex wave field that persists for quite a while."

Big quake question: Is nature out of control?
Seismic shockers are to be expected, but planet seems to be more active

Chile is on a hotspot of sorts for earthquake activity. And so the 8.8-magnitude temblor that shook the region overnight was not a surprise, historically speaking. Nor was it outside the realm of normal, scientists say, even though it comes on the heels of other major earthquakes.

One scientist, however, says that relative to the time period from the mid-1970s to the mid-1990s, Earth has been more active over the past 15 years or so. 

The Chilean earthquake, and the tsunami it spawned, originated on a hot spot known as a subduction zone, where one plate of Earth's crust dives under another. It's part of the active "Ring of Fire," a zone of major crustal plate clashes that surround the Pacific Ocean.

"This particular subduction zone has produced very damaging earthquakes throughout its history," said Randy Baldwin, a geophysicist with the U.S. Geological Survey.

The largest quake ever recorded, magnitude 9.5, occurred along the same fault zone in May 1960.

Even so, magnitude-8 earthquakes occur globally, on average, just once a year. Since magnitudes are given on a logarithmic scale, an 8.8-magnitude is much more intense than a magnitude 8, and so this event would be even rarer, said J. Ramón Arrowsmith, a geologist at Arizona State University.

Is Earth shaking more?
The Ryukyu Islands of Japan were hit with a 7.0-magnitude quake on Friday night. News of that tremor, the Haiti quake and now Chile may make it seem as if Earth is becoming ever more active. But in the grand scheme of things, geologists say this is just Mother Nature as usual.

"From our human perspective with our relatively short and incomplete memories and better and better communications around the world, we hear about more earthquakes and it seems like they are more frequent," Arrowsmith said. "But this is probably not any indication of a global change in earthquake rate of significance."

Coupled with better communication, as the human population skyrockets and we move into more hazardous regions, we're going to hear more about the events that do occur, Arrowsmith added.

However, "relative to the 20-year period from the mid-1970s to the mid 1990s, the Earth has been more active over the past 15 or so years," said Stephen S. Gao, a geophysicist at Missouri University of Science and Technology. "We still do not know the reason for this yet. Could simply be the natural temporal variation of the stress field in the earth's lithosphere." (The lithosphere is the outer solid part of the Earth.)

While the Chilean earthquake wasn't directly related to Japan's 7.0-magnitude temblor, the two have some factors in common.

For one, any seismic waves that made their way from Japan to the Chilean coast could play a slight role in ground-shaking.

"It is too far away for any direct triggering, and those distances also make the seismic waves as they would pass by from the Haiti or Japan events pretty small because of attenuation," Arrowsmith told LiveScience. (Attenuation is the decrease in energy with distance.) "Nevertheless, if the Chilean fault surface were close to failure, those small waves could push it even closer."

In addition, both regions reside within the Ring of Fire, which is a zone surrounding the Pacific Ocean where the Pacific tectonic plate and other plates dive beneath other slabs of Earth. About 90 percent of the world's earthquakes occur along this arc. (The next most seismic region, where just 5 to 6 percent of temblors occur, is the Alpide belt, which extends from the Mediterranean region eastward.)

Colliding plates
The Chilean earthquake occurred at the boundary between the Nazca and South American tectonic plates. These rocky slabs are converging at a rate of 3 inches (80 mm) per year, according to the USGS. This huge jolt happened as the Nazca plate moved down and landward below the South American plate. This is called a subduction zone when one plate subducts beneath another.

(Over time, the overriding South American Plate gets lifted up, creating the towering Andes Mountains.)

The plate movement explains why coastal Chile has such a history of powerful earthquakes . Since 1973, 13 temblors of magnitude 7.0 or greater have occurred there, according to the USGS.

In fact, the Chile earthquake originated about 140 miles (230 kilometers) north of the source region of the magnitude 9.5 earthquake of May 1960, considered the largest instrumentally recorded earthquake in the world. The 1960 earthquake killed 1,655 people in southern Chile, unleashing a tsunami that crossed the Pacific and killed 61 people in Hawaii, Japan and the Philippines.

In November 1922, a magnitude-8.5 earthquake occurred about 540 miles (870 kilometers) to the north of Saturday's earthquake, triggering a local tsunami that inundated the Chile coast and crossed the Pacific to Hawaii.

Because Saturday's earthquake was so huge, the amount of shaking experienced in Chile would likely have caused just as much damage had a similar-sized event occurred elsewhere, said Baldwin, the USGS scientist.

"If [the quake] were in Los Angeles you'd probably have massive destruction too," Baldwin said in a telephone interview.

Located at one of the harbors. Haven't been able to glean which island yet.

Darn I cant see it.
