Michelle Bachelet, the Chilean President, said an evacuation of coastal areas on Easter Island, the Chilean territory famous for its monumental statues, was under way as the tsunami was expected to make landfall there imminently.
British experts said a tsunami was now radiating from the epicentre towards Hawaii and other settlements on the Pacific Ring of Fire.

The extent of the tsunami’s ferocity is not yet known, but it has already reached the southern Juan Fernandez Islands, about 400 miles off the coast of Chile, where it was reported to have caused “serious damage”.
The islands include one named after Robinson Crusoe, Daniel Defoe’s protagonist, and another named after Alexander Selkirk, the Scottish sailor whose real life experiences as a castaway are said to have inspired the 1719 novel.
An alert was issued by the US Pacific Tsunami Warning Centre which predicted damage to the Hawaiian coast from 9pm GMT today.
“Urgent action should be taken to protect lives and property,” the centre said in a bulletin. “All shores are at risk no matter which direction they face.”
The centre had earlier issued a tsunami warning for Chile and Peru, and a tsunami watch for Ecuador, Colombia, Antarctica, all of Central America and French Polynesia.
New Zealand also issued a tsunami alert, warning of a wall of water up to 10 feet high, with landfall due there at just after 6pm GMT.
The New Zealand National Crisis Management Centre warning said the greatest wave heights were expected between six and 12 hours after the initial arrivals.
Dr Brian Baptie, the British Geological Survey’s Head of Seismology, said: “This is largest earthquake to strike central Chile since a magnitude 6.7 earthquake in 2001.
“A 1.3 metre tsunami wave was observed at Valparaiso, 200 kilometres north of the epicentre about 20 minutes after the earthquake.
“Tsunami waves in the deep ocean travel about the same speed as a jet plane and would take about 15 hours to reach Hawaii and about 20 hours to reach the other side of the Pacific.”
Dr David Rothery, from the Open University’s Department of Earth and Environmental Sciences, said: “This morning’s magnitude 8.8 earthquake close to the Chilean coast has caused a tsunami that is now radiating away from the epicentre and travelling at several hundred kilometres per hour across the Pacific Ocean.
“The first waves are expected to Hawaii at 11:19 Hawaii Standard Time but are also travelling along the South America coast and will reach Colombia and Costa Rica after 1300 GMT.
He added: “A magnitude 8 quake is a rare event. On average there is only about one of these per year globally.”
Japan’s meteorological agency warned of a tsunami risk across large areas of the Pacific, as far away as the Antarctic, and in the Philippines officials warned low-lying coastal areas to prepare for a possible evacuation.

Hawaii blasts sirens, warns of possible tsunami

Hawaii blasts sirens, warns of possible tsunami
By JAYMES SONG, Associated Press Writer Jaymes Song, Associated Press Writer 54 mins ago

EWA BEACH, Hawaii – A tsunami triggered by the Chilean earthquake raced across the Pacific Ocean on Saturday, threatening Hawaii and the U.S. West Coast as well as hundreds of islands from the bottom of the planet to the top.

Sirens blared in Hawaii to alert residents to the impending waves, with authorities asking people living near the water to evacuate. On several South Pacific islands hit by a tsunami last fall, police evacuated tens of thousands of residents from the coast.

The first waves in Hawaii are expected to hit shortly after 11 a.m. Saturday (4 p.m. EST; 2100 GMT) and measure roughly 8 feet (2.5 meters) at Hilo. Most Pacific Rim nations however did not order evacuations, but advised people in low-lying areas to be on the lookout.

Unlike other tsunamis in recent years, emergency officials along the Pacific have hours to prepare and possibly evacuate residents.

“We’ve got a lot of things going for us,” said Charles McCreery, the director of the Pacific Tsunami Warning Center, which issues warnings to almost every country around the Pacific Rim and to most of the Pacific island states. “We have a reasonable lead time.

“We should be able to alert everyone in harm’s way to move out of the evacuation zones,” he said.

In Hawaii, boats and people near the coast were being evacuated. Hilo International Airport, located along the coast, was closed. In Honolulu, residents lined up at supermarkets to stock up on water, canned food and batteries. Cars lined up 15 long at several gas stations.

“These are dangerous, dangerous events,” said John Cummings, spokesman for the Honolulu Emergency Management Department.

In Tonga, where nine people died in a Sept. 29 tsunami, police and defense forces began evacuating people from low-lying coastal areas as they warned residents that tsunami waves about three feet (one meter) high could wash ashore within three hours.

“I can hear the church bells ringing to alert the people,” National Disaster Office deputy director Mali’u Takai said. “We will move up to 50,000 people to the interior and away from the coasts.”

Waves 6 feet (1.8 meter) above normal hit near Concepcion, Chile shortly after the quake.

On the island of Robinson Crusoe, a huge wave from the tsunami covered half the village of San Juan Batista and three people were missing, said Ivan de la Maza, the superintendent of Chile’s principal mainland port, Valparaiso.

A helicopter and a Navy frigate were enroute to the island to assist in the search, he said.

A tsunami warning — the highest alert level — was also in effect for Guam, American Samoa, Samoa and dozens of other Pacific islands. An advisory — the lowest level — has been extended to include Oregon, Washington state, parts of Alaska, and coastal British Colombia.

British Columbia is hosting the Winter Olympic Games, but provincial officials said the venues are not under threat.

The White House is keeping close watch on the Chilean quake, which has raised the possibility of a tsunami striking Hawaii. Presidential press secretary Robert Gibbs said the U.S. stands ready to help the Chilean people “in this hour of need.”

American Samoa Lt. Gov. Aitofele Sunia activated emergency services and called on residents of shoreline villages to move to higher ground. Police in Samoa issued a nationwide alert to begin coastal evacuations. The tsunami is expected to reach the islands Saturday morning.

In French Polynesia, tsunami waves up to 6 feet (2 meters) high swept ashore, but no damage was immediately reported.

Meanwhile, disaster management officials in Fiji said they have been warned to expect waves of as high as 7.5 feet (2.3 meters) to hit the northern and eastern islands of the archipelago and the nearby Tonga islands.

A lower-grade tsunami advisory was in effect for the coast of California and an Alaskan coastal area from Kodiak to Attu islands. Tsunami Center officials said they did not expect the advisory would be upgraded to a warning.

Waves were likely to hit Asian, Australian and New Zealand shores within 24 hours of Saturday’s quake. A tsunami wave can travel at up to 600 mph, said Jenifer Rhoades, tsunami program manager at the National Weather Service in Washington, DC.

The sirens in Hawaii will also be sounded again three hours prior to the estimated arrival time.

McCreery said he didn’t know how big the waves will be, but expected them to be the largest to hit Hawaii since 1964.

“If you’re in an evacuation zone, police or civil defense volunteers would instruct you to evacuate, or instructions will come out over the radio and TV,” said Shelly Ichishita, spokeswoman for the state’s civil defense.

If coastal areas are evacuated, visitors in Waikiki would be moved to higher floors in their hotels, rather than moved out of the tourist district, which could cause gridlock.

Some Pacific nations in the warning area were heavily damaged by a tsunami last year.

On Sept. 29, a tsunami spawned by a magnitude-8.3 earthquake killed 34 people in American Samoa, 183 in Samoa and nine in Tonga. Scientists later said that wave was 46 feet (14 meters) high.

Past South American earthquakes have had deadly effects across the Pacific.

A tsunami after a magnitude-9.5 quake that struck Chile in 1960, the largest earthquake ever recorded, killed about 140 people in Japan, 61 in Hawaii and 32 in the Philippines.

That tsunami was about 3.3 to 13 feet (one to four meters) in height, Japan’s Meteorological Agency said.

Japanese public broadcaster NHK quoted earthquake experts as saying the tsunami would likely be tens of centimeters (inches) high and reach Japan in about 22 hours.

A tsunami of 28 centimeters (11 inches) was recorded after a magnitude-8.4 earthquake near Chile in 2001.

The Meteorological Agency said it was still investigating the likelihood of a tsunami in Japan and did not issue a formal coastal warning.

Australia, meanwhile, was put on a tsunami watch.

The Joint Australian Tsunami Warning Center issued a tsunami warning Saturday night for a “potential tsunami threat” to New South Wales state, Queensland state, Lord Howe Island and Norfolk Island.

Any potential wave would not hit Australia until Sunday morning local time, it said.

New Zealand officials warned that “non-destructive” tsunami waves of less than three feet could hit the entire east coast of the country’s two main islands and its Chatham Islands territory, some 300 miles east of New Zealand.

The Philippine Institute of Vulcanology and Seismology issued a low-level alert saying people should await further notice of a possible tsunami. It did not recommend evacuations.

Seismologist Fumihiko Imamura, of Japan’s Tohoku University, told NHK that residents near ocean shores should not underestimate the power of a tsunami even though they may be generated by quakes on the other side of the ocean.

“There is the possibility that it could reach Japan without losing its strength,” he said.

Massive earthquake hits Chile, 122 dead

Massive earthquake hits Chile, 122 dead
By Alonso Soto Alonso Soto 28 mins ago

SANTIAGO (Reuters) – A huge magnitude-8.8 earthquake struck Chile early on Saturday, killing at least 122 people, knocking down homes and hospitals, and triggering a tsunami that rolled menacingly across the Pacific.

Buildings caught fire, major highway bridges collapsed and wide cracks opened up in streets. A 15-storey building collapsed in the city of Concepcion, near the epicenter, and overturned cars lay scattered below a fallen overpass in the capital.

Chilean President-elect Sebastian Pinera said at least 122 people had died in the quake, which struck at 3:34 a.m. (0634 GMT), sending many people rushing outside in their pajamas.

“Unfortunately, Chile is a country of catastrophes,” Pinera said, adding the quake dealt a heavy blow to the country’s roads, airports and ports.

He said the death toll could still rise, but an emergency official said it was unlikely to increase dramatically.

Tsunami warnings were posted around the Pacific, including the U.S. state of Hawaii, Japan and Russia.

Telephone and power lines were down across large swathes of central Chile, making it difficult to assess the full extent of the damage close to the epicenter.

The South American country is the world’s No. 1 copper producer, and the quake halted operations at two major mines.

The U.S. Geological Survey said the earthquake struck 70 miles northeast of Concepcion at a depth of 22 miles.

The capital Santiago, about 200 miles north of the epicenter, was also badly hit. The international airport was closed for at least 24 hours as the quake destroyed passenger walkways and shook glass out of doors and windows.

“I thought I’d blown a tire … but then I saw the highway moving like it was a piece of paper and I realized it was something much worse,” said one man who was forced to abandon his car on a wrecked highway overpass.

Chile’s Codelco, the world’s largest copper producer, suspended operations at its El Teniente and Andina mines, but reported no major damage and said it expected the mines to be up and running in the “coming hours.”

Production was halted at the Los Bronces and El Soldado copper mines, owned by Anglo American Plc, but Chile’s biggest copper mine, Escondida, was operating normally.

Chile produces about 34 percent of world supply of copper, which is used in electronics, cars and refrigerators.

TSUNAMI

Chilean President Michelle Bachelet said a huge wave hit the Juan Fernandez islands, and archipelago where Scottish sailor Alexander Selkirk was marooned in the 18th century inspiring the novel Robinson Crusoe.

“There was a series of waves that got bigger and bigger, which gave people time to save themselves,” pilot Fernando Avaria told TVN television by telephone from the main island. Three people were killed and four missing there, he said.

Bachelet said residents were evacuated from coastal areas of Chile’s remote Easter Island, a popular tourist destination in the Pacific famous for its towering Moai stone statues.

Unusually big waves battered Ecuador’s Galapagos Islands, where residents were moved to higher ground as a precaution.

The Pacific Tsunami Warning Center issued a Pacific-wide tsunami warning for the U.S. state of Hawaii and countries as far away as Japan, Russia, Philippines, Indonesia and the South Pacific. French Polynesia was also put on alert.

“Chile probably got the brunt force of the tsunami already. So probably the worst has already happened in Chile,” said Victor Sardina, geophysicist at the warning center.

“The tsunami was pretty big too. We reported some places around 8 feet. And it’s quite possible it would be higher in other areas,” he added.

An earthquake of magnitude 8 or over can cause “tremendous damage,” the USGS says. The January 12 quake that devastated Haiti’s capital Port-au-Prince was measured as magnitude 7.0.

In 1960, a massive earthquake in Chile generated waves that reached the Philippines in about 24 hours.

FLAMES, LOOTING

Local television showed a building in flames in Concepcion, one of Chile’s largest cities with around 670,000 inhabitants. Some residents looted pharmacies and a collapsed grains silo, hauling off bags of wheat, television images showed.

Broken glass and chunks of concrete and brick were strewn across roads and several strong aftershocks rattled jittery residents in the hours after the initial quake.

In the moments after the quake, people streamed onto the streets of the Chilean capital hugging each other and crying.

“My house is completely destroyed, everything fell over … it has been totally destroyed. Me and my wife huddled in a corner and after hours they rescued us,” said one elderly man in central Santiago.

There were blackouts in parts of Santiago. Emergency officials said buildings in the historic quarters of two southern cities, mainly made of adobe, had been badly damaged and local radio said three hospitals had partially collapsed.

In 1960, Chile was hit by the world’s biggest earthquake since records dating back to 1900. The 9.5 magnitude quake devastated the south-central city of Valdivia, killing 1,655 people and sending a tsunami that battered Easter Island 2,300 miles off Chile’s Pacific coast and continued as far as Hawaii, Japan and the Philippines.

Saturday’s quake shook buildings as far away as Argentina’s Andean provinces of Mendoza and San Juan. A series of strong aftershocks rocked Chile’s coastal region from Valdivia in the south to Valparaiso, about 500 miles to the north.

The United Nations and the White House said they were closely monitoring the situation in Chile and the potential threat of tsunamis in the Pacific.

“We stand ready to help (Chile) in this hour of need,” White House spokesman Robert Gibbs said.

A State Department official said Secretary of State Hillary Clinton was being kept apprised of the situation in Chile, which she is due to visit on Tuesday on a Latin American tour.

Hundreds of Quakes Are Rattling Yellowstone

By KIRK JOHNSON
Published: January 31, 2010

DENVER — In the last two weeks, more than 100 mostly tiny earthquakes a day, on average, have rattled a remote area of Yellowstone National Park in Wyoming, putting scientists who monitor the park’s strange and volatile geology on alert.

Researchers say that for now, the earthquake cluster, or swarm — the second-largest ever recorded in the park — is more a cause for curiosity than alarm. The quake zone, about 10 miles northwest of the Old Faithful geyser, has shown little indication, they said, of building toward a larger event, like a volcanic eruption of the type that last ravaged the Yellowstone region tens of thousands of years ago.

The area is far from any road or community, and the park is relatively empty in winter. Swarms of small quakes, including a significant swarm last year, are relatively common.

But at a time when the disastrous earthquake in Haiti on Jan. 12 has refocused global attention on the earth’s immense store of tectonic energy, scientists say that the Yellowstone swarm, if only because of its volume, bears close observation: as of Sunday, there had been 1,608 quakes since Jan. 17.

“We’re not seeing a pattern that is really discernible yet,” said Henry Heasler, a coordinating scientist for the Yellowstone Volcano Observatory, a joint venture of Yellowstone, the United States Geological Survey and the University of Utah. Dr. Heasler said plans were in place to intensify observations in case the swarm continued for a long time or got larger. “We’re ready to ramp up,” he said, including using flights to monitor the area.

Researchers at the University of Utah’s Seismograph Stations who have tracked Yellowstone swarms said they thought it was coincidental that another big swarm of more 1,000 quakes had struck the park just over a year ago. At the time, it was the second-biggest cluster recorded there. The largest swarm was in 1985, when 3,000 earthquakes struck over three months.

Last year’s swarm, beneath northern Yellowstone Lake, had a specific track of alignment, with the earthquakes moving north and growing shallower from the initial quake area, said Robert B. Smith, a professor of geophysics at the University of Utah and a science coordinator at the Yellowstone Volcano Observatory.

The mostly smaller quakes in the current swarm, he said, are more like a cloud, with no directional pattern, similar to what scientists saw in a big swarm at the park in 1999. “We think the crust beneath Yellowstone is highly fractured already, so we’re getting stress release in these earthquakes — a displacement of millimeters,” Dr. Smith said.

Dr. Heasler said researchers use the park’s geologic wonders, like Old Faithful — which spews steam and water on schedule, plus or minus 10 minutes — as indicators of the effects of quake activity. He and his team look for changes in water temperature, or mud plumes in hot pools that otherwise run clear. This swarm, he said, seems not to have affected any of those natural monitors, though he emphasized that analysis was continuing.

Attention to earthquakes in general has soared since the quake in Haiti. For instance, visits to the United States Geological Survey’s Earthquake Hazards Program Web site increased fivefold after the quake, to more than a million a day, compared with the numbers a month earlier, an agency spokeswoman said.

Dr. Heasler said park visitors had been encouraged to help with the research by telling park officials if they felt the ground shake.
