The 2016 Chiloé earthquake with a magnitude of Mww 7.6 struck 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.

The earthquake occurred as a result of shallow thrust faulting in southern Chile.

The location, depth and shallow thrusting focal mechanism solution[3] all indicate this earthquake likely occurred on the subduction zone interface.

[1] A tsunami with a maximum height of 0.44 m (1.4 ft) was observed on Chiloé Island.
