Sabe-se que atingiu 8.8 na escala de Richter, que morreram pessoas, há vários feridos e muita coisa destruída, incluindo na cidade de Santiago. Pelo que pude perceber, números e outros dados são ainda confusos e bastante contraditórios.

Tentarei ir actualizando este post, embora não prometa mais que 'copy+past', com as informações, links e sites que me parecerem mais úteis.







[ACTUALIZAÇÃO]

Coberturas de Media do Chile:
  • follow live-blog coverage of the earthquake aftermath on the Web sites of the Chilean newspapers La Tercera and El Mercurio.
  • La Tercera also has video, photos and reactions from world leaders on its home page, along with audio of Chile’s interior minister, Pérez Yoma, describing the country’s response to the earthquake.
  • Carmen Fernández, the director of Chile’s emergency response office, Onemi

As my colleagues Alexei Barrionuevo and Liz Robbins report, an 8.8 magnitude earthquake struck off the coast of Chile on Saturday morning, setting off a tsunami warning across much of the Pacific.

“TSUNAMI WARNING CANCELLATION.” It states:
BASED ON ALL AVAILABLE DATA THERE IS NO LONGER A DESTRUCTIVE TSUNAMI THREAT TO THE STATE OF HAWAII. THEREFORE THE TSUNAMI WARNING FOR HAWAII IS CANCELED.
HOWEVER SOME COASTAL AREAS IN HAWAII MAY CONTINUE TO EXPERIENCE SMALL SEA LEVEL CHANGES AND STRONG OR UNUSUAL CURRENTS LASTING FOR SEVERAL MORE HOURS.

Here is video of President Obama’s remarks earlier this afternoon at the White House:



Kristina Wong of ABC News reported that Mr. Obama had met earlier in the day with officials in the White House situation room as his home state of Hawaii prepared for potentially deadly tsunami waves triggered by the earthquake.

The Associated Press obtained video from surveillance cameras in Chile’s capital, showing the shaking caused by the earthquake early on Saturday, more than 200 miles from the epicenter:


1:32 p.m. |Estimated Arrival Times of Tsunami Waves

The Web site of the American West Coast and Alaska Tsunami Warning Center posted this map with estimated arrival times of tsunami waves generated by Saturday morning’s earthquake off the coast of Chile:

Unlike an earlier map from the same source that we posted, which was used for a drill in 2006, this is a forecast based on today’s earthquake.
The Tsunami Warning Center’s Web site also has data on tsunami waves that have already been observed along the coast of South America.

The Web site of the U.S. Geological Survey has a lot of information about the 1960 earthquake in a fascinating and useful report called “Surviving a Tsunami—Lessons from Chile, Hawaii, and Japan.”

The Tsunami Warning Center has a very detailed list of estimated arrival times for waves generated by Saturday’s 8.8 magnitude earthquake at many locations along the west coast of the United States.
The same Web site also has this map, which was produced for a Pacific-wide tsunami drill conducted in May, 2006 with estimated arrival times for waves produced by hypothetical magnitude 9.2 earthquake off the coast of central Chile:

Philippines orders limited evacuation | 8:48 p.m. ET
Reuters reports that the Philippines government has ordered a precautionary evacuation on Sunday along its eastern seaboard after raising the level of a tsunami alert.
 "At 7 a.m. today, we raised the tsunami alert to level 2 and People are advised to stay away from beaches and to report unusual big waves in their areas," Renato Solidum, director of the Philippine Institute of Volcanology and Seismology, told Reuters.
 "There's only limited evacuation in some areas where communities are near the water," he said, adding local officials have the authority to force residents to move to safer areas.
 And in Australia, the possibility of a tsunami apparently didn’t deter beach-goers, according to newspaper reports.
  
From the Web site of Britain’s Channel 4 News, here is video shot early this morning of a fire in Chile’s second-largest city, Concepcion, which is located just 70 miles from the epicenter of the earthquake:



Here is MSNBC’s live coverage, which, at the moment, appears to be devoted to a stream of coverage from Hawaii:



This footage, obtained by The Associated Press, was shot in Santiago this morning, more than 200 miles from the epicenter of the earthquake:


This video report from ITN News in Britain shows some earlier images from the pre-dawn hours in Chile:



About one hour ago, Reuters reported that a bulletin from the Pacific Tsunami Warning Center said: “Urgent action should be taken to protect lives and property.” The warning also noted: “All shores are at risk no matter which direction they face.”
The latest alert from the Pacific Tsunami Warning Center, issued on Saturday morning, says “a widespread tsunami warning is in effect.”

The bulletin says:
SEA LEVEL READINGS CONFIRM THAT A TSUNAMI HAS BEEN GENERATED WHICH COULD CAUSE WIDESPREAD DAMAGE. AUTHORITIES SHOULD TAKE APPROPRIATE ACTION IN RESPONSE TO THIS THREAT. THIS CENTER WILL CONTINUE TO MONITOR SEA LEVEL DATA TO DETERMINE THE EXTENT AND SEVERITY OF THE THREAT.
The bulletin makes clear that the warning is in effect across much of the Pacific:
A TSUNAMI WARNING IS IN EFFECT FOR:
CHILE / PERU / ECUADOR / COLOMBIA / ANTARCTICA / PANAMA / COSTA RICA / NICARAGUA / PITCAIRN / HONDURAS / EL SALVADOR / GUATEMALA / FR. POLYNESIA / MEXICO / COOK ISLANDS / KIRIBATI / KERMADEC IS / NIUE / NEW ZEALAND / TONGA / AMERICAN SAMOA / SAMOA / JARVIS IS. / WALLIS-FUTUNA / TOKELAU / FIJI / AUSTRALIA / HAWAII / PALMYRA IS. / TUVALU / VANUATU / HOWLAND-BAKER / NEW CALEDONIA / JOHNSTON IS. / SOLOMON IS. / NAURU / MARSHALL IS. / MIDWAY IS. / KOSRAE / PAPUA NEW GUINEA / POHNPEI / WAKE IS. / CHUUK / RUSSIA / MARCUS IS. / INDONESIA / N. MARIANAS / GUAM / YAP / BELAU / JAPAN / PHILIPPINES / CHINESE TAIPEI
A report on the 8.8 magnitude earthquake on the Web site of the U.S. Geological Survey says that it took place at 3:34:14 a.m. local time 21.7 miles beneath the earth’s surface, about 70 miles northeast of Concepcion, Chile’s second-largest city, home to more than 200,000 people, and about 200 miles southwest of the country’s capital, Santiago. The U.S.G.S. puts the earthquake, which was nearly 500 times as strong as the one that hit Haiti last month, in historical perspective:
Coastal Chile has a history of very large earthquakes. Since 1973, there have been 13 events of magnitude 7.0 or greater. The February 27 shock originated about 230 km north of the source region of the magnitude 9.5 earthquake of May, 1960 – the largest instrumentally recorded earthquake in the world. This magnitude 9.5 earthquake killed 1655 people in southern Chile and unleashed a tsunami that crossed the Pacific, killing 61 people in Hawaii, Japan, and the Philippines. Approximately 870 km to the north of the February 27 earthquake is the source region of the magnitude 8.5 earthquake of November, 1922. This great quake significantly impacted central Chile, killing several hundred people and causing severe property damage. The 1922 quake generated a 9-meter local tsunami that inundated the Chile coast near the town of Coquimbo; the tsunami also crossed the Pacific, washing away boats in Hilo harbor, Hawaii. The magnitude 8.8 earthquake of February 27, 2010 ruptured the portion of the South American subduction zone separating these two massive historical earthquakes.
A large vigorous aftershock sequence can be expected from this earthquake.
The Honolulu Advertiser has live video of Waikiki Beach and frequent updates on its Web site, as the islands brace for the impact of potentially dangerous tsunami waves.
This live video from Hawaii is being fed by a CBS affiliate there :


As we noted earlier, KHON, another local news station in Hawaii, is also streaming video of their coverage
