The shock was centered southwest of Santiago, Chile, with a focal depth of . ==Earthquake== The 9 April 1985 Pichilemu earthquake occurred in the same fault area as the 2010 Pichilemu earthquake, and is considered by University of Chile Seismological Service a thrust fault-type interplate earthquake. The earthquake, measured in the Modified Mercalli intensity, reached magnitude VI in Curacaví, La Calera, Los Andes, Peñaflor, San Antonio, Valparaíso, and Viña del Mar; and magnitude V–VI in Concón, Constitución, Curicó, La Ligua, Melipilla, Papudo, Pichilemu, Puchuncaví, Quilpué, and Villa Alemana.〔 The earthquake was felt throughout much of central Chile from La Serena to Osorno. It was also felt in Mendoza, San Juan, San Luis, Córdoba, Tucumán, and Santa Fe provinces in Argentina.〔 According to national radio networks, the tremors "were felt along a 1,000-mile stretch of Chile from Copiapó in the north to Valdivia in the south and across the Andes mountains in Argentina".〔 Although it has been considered by the news media as an aftershock of the main Santiago earthquake,〔 according to Rosa Urrutia de Hazbún and Carlos Lanza Lazcano's book ''Catástrofes en Chile 1541–1992'', the Pichilemu earthquake was a different and separate event. Mario Pardo, the director of the Chilean Seismological Service, told international press in April 1985 that it was "apparently an aftershock from the March 3 earthquake that killed 177 in central Chile" and that "the quake was centered in the ocean off the coast near Pichilemu, a city 100 miles southwest of Santiago". According to national radio networks, the tremors "were felt along a 1,000-mile stretch of Chile from Copiapó in the north to Valdivia in the south and across the Andes Mountaines in Argentina".〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「1985 Pichilemu earthquake」の詳細全文を読む スポンサード リンク
