A 6.9 magnitude earthquake occurred on March 11, 2010, 40 kilometers southwest from Pichilemu, O'Higgins Region, Chile.[2][3][4][5][6] A general tsunami warning was not issued by the Pacific Tsunami Warning Center Pacific-wide, although they warned about the possibility of local tsunamis within 100 kilometers of the epicenter (between San Antonio and Concepción).[7]

Although news media reported the earthquake as an aftershock of the February earthquake in Chile,[8][9] a preliminary geological summary given by the United States Geological Survey [10] considers it an independent earthquake. Though caused by by the regional stress caused by the February 27 earthquake, the March event was not an immediate adjustment to February's thrust fault rupture between the Nazca and South American plates, but was caused by normal faulting inside one of those plates. However, it has yet not been reliably determined in which plate the earthquake occurred.
Damage reported by the Chilean news media includes a collapsed pedestrian crossing over Chile Highway 5, north of Rancagua.[11] The place most affected by the earthquake was Pichilemu, the epicentre of the earthquake. It destroyed Ross Park, most of the Ross Casino and many houses in Espinillo and Rodeillo.[12] No casualties were reported.
The earthquake took place shortly before the new president, Sebastián Piñera, was sworn in, at about 12:15 PM local time (15:15 UTC), at the Chilean congress in Valparaíso, where the shaking was clearly felt. The presidents of Bolivia, Paraguay, and Ecuador were present when the earthquake occurred, however, the television footage showed that the inauguration was not interrupted.[13]
Within the following six hours there were ten aftershocks, two of magnitude 6 or greater, and seven between 5 and 6. There were many aftershocks of lesser magnitude (up to 5) in the next four days.[14]

Although news media first reported the earthquake as an aftershock of the February earthquake[8][9], the initial geological summary given by the United States Geological Survey [10] said it was an independent earthquake. Though unchained by the regional stress caused by the February 27 earthquake, the March event was not an immediate adjustment to February's thrust fault rupture between the Nazca and South American plates, but it was caused by normal faulting inside one of those plates. However, it has not been confidently decided in which plate the earthquake occurred.
Within 6 hours, 10 aftershocks took place, of these 2 were of magnitude 6 or greater and 7 between magnitude 5 and 6.[11]

The May, 2 2010 Pichilemu earthquake was a magnitude 6.0 MW earthquake that struck off Pichilemu, Chile, at 10:52 AM on May 2, 2010 at the epicenter, at a depth of 31 kilometres (19 mi). USGS described that the epicenter was 70 kilometres (43 mi) south-southwest of San Antonio, 105 kilometres (65 mi) west Regional capital of Rancagua, 105 kilometres (65 mi) northwest of Curicó and 140 kilometres (87 mi) southwest of the Chilean capital of Santiago.[16]
After almost exactly three hours later a second quake occurs in the same area with an intensity of 4.8 MW[17]
More than 10 aftershocks were produced in May 2 and 3.
