Tsunami alert as Chile hit by powerful earthquake 8.3-magnitude

A powerful earthquake has hit central Chile, causing buildings to sway in the capital Santiago, officials say.
The 8.3-magnitude tremor was centred off the coast, about 144 miles (232km) north-west of the capital.

The Pacific Tsunami Warning Center warned that "widespread hazardous tsunami waves are possible".
One person was killed by a falling wall, and evacuation was ordered in coastal areas. Tsunami sirens were heard in the port of Valparaiso.
Chilean officials say the earthquake has produced waves of up to 4.5 metres (15 feet) along the coast in the region of Coquimbo.

The earthquake struck just off the coast at 19:54 local times (22:54 GMT), about 55km west of the city of Illapel, the US Geological Survey said.

Officials said it was at the depth of about 10km.

The US Geological Survey initially reported the tremor as magnitude 7.9, but then quickly revised the reading to 8.3.
Several strong aftershocks were reported just minutes later.

Illapel Mayor Denis Cortes reported that one person was killed by a collapsing wall, and 15 other people were injured.

Some homes were reportedly damaged in the city.

"Tsunami waves reaching more than three metres above the tide level are possible along some coasts of Chile," the Pacific Tsunami Warning Center warned.

The earthquake struck as thousands of Chileans have been travelling to the coast ahead of a week of celebrations of the national holidays, or Fiestas Patrias.

Tsunami alerts were also issued for Peru, Hawaii, parts of California and as far away as New Zealand.

New Zealand authorities warned of unusually strong currents and unpredictable water flows, reported local media. At least one school has evacuated.

The quake was also strongly felt in some Argentine provinces like Mendoza and in the capital Buenos Aires several buildings were evacuated, the BBC's Ignacio de los Reyes reports.
Chile is one of the most seismically active locations on the globe.
It runs along the boundary between the Nazca and South American tectonic plates. These are vast slabs of the Earth's surface that grind past each other at a rate of up to 80mm per year.
In February 2010, a 8.8-magnitude struck off central Chile, killing more than 500 people.

  2. Powerful Chile quake kills two, sparks tsunami alert....

    A massive 8.3-magnitude earthquake struck the centre of Chile on Wednesday, triggering the evacuation of coastal areas and warnings that tsunami waves could reach as far as Japan.

    At least two people were killed and 10 hurt in Chile, where thousands of terrified residents rushed out onto the streets in the capital Santiago. The quake was felt as far away as Argentina, where buildings also swayed.

    The United States Geological Survey (USGS) put the shallow offshore quake at a magnitude of 8.3 and said it hit just 228 kilometres north of Santiago, a city of 6.6 million people.

    The quake, which struck at 7.54 pm, hit at a depth of eight kilometres, USGS said. Seismologists also reported two aftershocks, both above 6.0.

    The Chilean government put the main earthquake at 8.0 on the Richter scale..........AFP

    The Ministry of Civil Defence and Emergency Management (MCDEM) issued a tsunami warning for East Cape, Chatham Islands, Coromandel and Banks Peninsula.

  5. Séisme de magnitude 8,3 au Chili: 5 morts, un million de personnes évacuées ...

    Un million de personnes ont été évacuées en raison d'une alerte au tsunami déclenchée après un violent séisme mercredi soir dans le centre du Chili, séisme qui a fait au moins cinq morts et un disparu. Les personnes décédées sont deux femmes et trois hommes. Une grande partie des personnes évacuées ont été transférées vers les zones plus élevées des villes côtières.

    "Le plus fort tremblement de terre pour 2015 à l'échelle mondiale"

    "Nous déplorons le décès de cinq citoyens chiliens (...). Nous évaluons le nombre d'évacués à un million de personnes", a indiqué le sous-secrétaire du ministère de l'Intérieur, Mahmoud Aleuy.

    Mahmoud Aleuy a précisé que l'état de catastrophe avait été prononcé pour la province de Choapa, où se situe l'épicentre du séisme d'une magnitude de 8,3 selon l'Institut américain de géologie (USGS). "Il s'agit du sixième tremblement de terre le plus fort de l'histoire du Chili, et du plus fort pour 2015 à l'échelle mondiale", a souligné le responsable du ministère.

    L'île de Pâques évacuée

    La Marine chilienne a lancé une alerte au tsunami pour l'ensemble des 4000 km de côtes du pays, bordé par l'océan Pacifique. L'ordre d'évacuation des habitants des villes côtières était maintenu dans la nuit, à l'exception des régions de Los Lagos, Aysen et Magallanes, dans le sud.

    L'île de Pâques, à 3750 kilomètres au large, devait elle aussi être évacuée, tandis qu'une alerte au tsunami était émise dans le Pacifique, côté asiatique, concernant surtout la Polynésie française.

    Sur la côte du Chili, des grandes vagues ont atteint le centre de plusieurs villes, dans la région de Coquimbo où a eu lieu le séisme et dans celle de Valparaiso, à 120 kilomètres à l'ouest de la capitale, selon des images de la télévision.

    "Même s'il y a bien eu un tsunami, les dernières séries de vagues sont en diminution, mais nous savons qu'il peut y avoir des répliques et donc nous devons continuer à évaluer minute par minute la situation", a déclaré la présidente Michelle Bachelet.......http://www.rtbf.be/info/monde/amerique-du-sud/detail_alerte-au-tsunami-au-chili-apres-un-tres-fort-seisme?id=9082267
