M 8.3 deadly earthquake triggers Tsunami from Chile, Tahiti to Hawaii, California


Magnitude 8.3 massive earthquake rattled Chile at 19:54 local time (22:54 GMT), the U.S. Geological Survey reported.

According to the U.S. Geological Survey, the quake's epicenter was located 46 km W of Illapel, Chile. It was 15.5 miles deep.

Tsunami advisories are in effect for Hawaii and Southern California. The tsunami is fanning out across much of the Pacific Ocean, though the worst of its power is expected to be focused westward toward French Polynesia, including Tahiti, The Weather Channel reported. Tahiti is the largest island in French Polynesia and a popular vacation destination.

According to BBC, the recent Chile earthquake is five times more energetic than the one that devastated Nepal back in April. At least 10 people have died in the recent Chile earthquake.

The Pacific Typhoon Warning Center has issued a tsunami advisory for Hawaii predicting waves of 1 to 3 feet. Similarly, the U.S. government's National Tsunami Warning Center (NTWC) has issued a tsunami advisory for Southern California expecting tsunami waves of less than 1 foot above normal tide levels.

The French High Commission has warned the people on the Marquesas Islands to prepare for waves of up to 1.4 metres following today's Chilean tsunami. Early ground reports from Tahiti indicate there was a wave of around 30 centimetres height in Papeete, Radio New Zealand International said.

The quake was immediately followed by four aftershocks of 6.0 or greater magnitude within 30 minutes. The tremors measured 6.3, 6.1, 6.2 and 7.0, striking at 7:59, 8:03, 8:16 and 8:18 local time, respectively.

According to USGS, earthquake occurred as the result of thrust faulting on the interface between the Nazca and South America plates in Central Chile.
