LOS ANGELES (LALATE) – A strong Chile earthquake today 2014 has struck San Antonio. The terremoto en Chile hoy, a strong 5.2 magnitude temblor, started in the morning. Damage assessment is pending.
USGS indicates to news that a 5.2 magnitude Chile earthquake today began just after 4:16 am local time. The quake was shallow. Reps tell news that the quake started only nine miles below ground level. As a result the quake could be felt across the area. Officials tell news that the quake was twenty-eight miles west of San Antonio. It was thirty miles west of Cartagena and roughly fifty miles west of Melpilla. The quake was also fifty-three miles southwest of Valparaiso.
Some Chile residents still remember the 1965 quake which at a 7.4 magnitude took the lives of four hundred residents. It came only five years after the horrific 9.5 magnitude quake which killed 1,655 residents. Listed as the largest earthquake ever, the 1960 Chile quake resulted in “1,655 killed, 3,000 injured, 2,000,000 homeless, and $550 million damage in southern Chile” reports USGS. A “tsunami caused 61 deaths, $75 million damage in Hawaii; 138 deaths and $50 million damage in Japan; 32 dead and missing in the Philippines; and $500,000 damage to the west coast of the United States.”
USGS tells news that “three segments are characterized by steeply dipping subduction; the other two by near-horizontal subduction. The Nazca plate beneath northern Ecuador, southern Peru to northern Chile, and southern Chile descend into the mantle at angles of 25° to 30°.” They add that “In contrast, the slab beneath southern Ecuador to central Peru, and under central Chile, is subducting at a shallow angle of approximately 10° or less. In these regions of flat-slab subduction, the Nazca plate moves horizontally for several hundred kilometers before continuing its descent into the mantle, and is shadowed by an extended zone of crustal seismicity in the overlying South America plate.”
