The 2010 Chile earthquake occurred off the coast of central Chile on Saturday, 27 February 2010, at 03:34 local time (06:34 UTC), having a magnitude of 8.8 on the moment magnitude scale, with intense shaking lasting for about three minutes.[5][1][2][6] It ranks as the sixth largest earthquake ever to be recorded by a seismograph. It was felt strongly in six Chilean regions (from Valparaíso in the north to Araucanía in the south), that together make up about 80 percent of the country's population. According to the United States Geological Survey (USGS) the cities experiencing the strongest shaking—VIII (Destructive) on the Mercalli intensity scale (MM)—were Arauco and Coronel. According to Chile's Seismological Service Concepción experienced the strongest shaking at MM IX (Violent).[1] The earthquake was felt in the capital Santiago at MM VII (Very Strong)[3] or MM VIII.[1] Tremors were felt in many Argentine cities, including Buenos Aires, Córdoba, Mendoza and La Rioja.[7][8] Tremors were felt as far north as the city of Ica in southern Peru (approx. 2400 km).[9] The earthquake triggered a tsunami which devastated several coastal towns in south-central Chile and damaged the port at Talcahuano. Tsunami warnings were issued in 53 countries,[10] and the wave caused minor damage in the San Diego area of California[11] and in the Tōhoku region of Japan, where damage to the fisheries business was estimated at ¥6.26 billion (USD$66.7 million).[12] The earthquake also generated a blackout that affected 93 percent of the country's population and which went on for several days in some locations.[13] President Michelle Bachelet declared a "state of catastrophe" and sent military troops to take control of the most affected areas. According to official sources, 525 people lost their lives, 25 people went missing[4] and about 9% of the population in the affected regions lost their homes.[14] On 10 March, Swiss Reinsurance Co. estimated that the Chilean quake would cost the insurance industry between 4 and 7 billion dollars. The rival German-based Munich Re AG made the same estimate.[15] Earthquake’s losses to economy of Chile are estimated at US$15–30 billion.[16] Contents [hide]

According to the USGS the epicenter of the earthquake was about 3 km (1.9 miles) off the coast of Pelluhue commune in the Maule Region. This is about 6 km (3.7 miles) west of the village of Chovellén, 15 km (9.3 miles) southwest of the town of Pelluhue and at a point approximately 100 km (62 miles) away from the following four provincial capitals: Talca (to the north-east),...
