The 2010 Chile earthquake occurred off the coast of central Chile on Saturday, 27 February at 03:34:12 local time, having a magnitude of 8.8 on the moment magnitude scale, with intense shaking lasting for about three minutes. It was felt strongly in six Chilean regions 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 (Severe) on the Mercalli intensity scale (MM)—were Concepción, Arauco, and Coronel. According to Chile's Seismological Service, Concepción experienced the strongest shaking at MM IX (Violent). The earthquake was felt in the capital Santiago at MM VII or MM VIII. Tremors were felt in many Argentine cities, including Buenos Aires, Córdoba, Mendoza, and La Rioja. Tremors were felt as far north as the city of Ica in southern Peru. It is the largest earthquake to hit Chile since the 1960 Valdivia earthquake.

Events in the year 2013 in Costa Rica.

The 1822 Costa Rica earthquake had an estimated surface-wave magnitude of 7.5–7.6 and struck the nation's Caribbean coast. The earthquake largely affected the country's east coast and generated a tsunami. Thrust faulting was inferred as a plausible mechanism for the earthquake and its damage pattern was similar to a 1991 shock of similar magnitude. Damage was also recorded in neighbouring countries.
