5.7-magnitude quake strikes off Indonesia: USGS
JAKARTA - A 5.7-magnitude earthquake struck off Indonesia's Sulawesi island on Tuesday morning, the United States Geological Survey said.
The quake hit at 5:41 am local time (2141 GMT Monday) 135 kilometres (83 miles) north-west of Gorontalo city at a depth of 46 kilometres.
The USGS' Prompt Assessment of Global Earthquakes for Response (PAGER) system estimated the risk of fatalities and economic damage as very low.
Indonesia sits on the Pacific "Ring of Fire" where tectonic plates collide, causing frequent seismic and volcanic activity.
A 6.1-magnitude quake that struck Aceh province in July killed at least 35 people and left thousands homeless.
