The 2016 Chiloé earthquake with a magnitude of Mww 7.6 struck that 225 kilometres (140 mi) south-west of Puerto Montt in southern Chile at 11:22 local time, 25 December.[1][2] The earthquake triggered a tsunami warning on coasts located up to 1,000 kilometres (620 mi) from the quake's epicentre, generating massive evacuation across the Greater Chiloé Island, after advice from the Chilean government.[2] Although there was damage in some parts of the island, the government reported no casualties.
Earthquake[]
The earthquake occurred as a result of shallow thrust faulting in southern Chile. At the location of the earthquake, the oceanic Nazca plate converges with and subducts beneath the South America plate in an east-northeast direction, at a rate of approximately 73 mm/yr. The location, depth and shallow thrusting focal mechanism solution[3] all indicate this earthquake likely occurred on the subduction zone interface.[1]
