SUMATERA, Indonesia (Reuters): An earthquake measuring 5.7 magnitude struck Halmahera Sea in Indonesia on Monday, the German Research Centre for Geosciences (GFZ) said.
The quake was at a depth of 10 kilometers (6.21 miles) GFZ said. It was also reported no immediate tsunami but warned of possible aftershocks.
Indonesia, a vast archipelago nation, experiences frequent earthquakes due to its position on the Pacific "Ring of Fire", an arc of intense seismic activity where tectonic plates collide that stretches from Japan through Southeast Asia and across the Pacific basin.
A 6.2-magnitude quake that shook Sulawesi island in January 2021 killed more than 100 people and left thousands homeless.
In 2018, a 7.5-magnitude quake and subsequent tsunami in Palu on Sulawesi killed more than 2,200 people.
And in 2004, a 9.1-magnitude quake struck Aceh province, causing a tsunami and killing more than 170,000 people in Indonesia.
In November last year, a 5.6-magnitude quake hit the South-East Asian nation's Java island, killing 602 people.
Most of the victims of that earthquake were killed when buildings collapsed or in landslides triggered by the tremor.
A 6.1-magnitude earthquake struck off the country's Sumatra island in April, shaking homes of panicked residents but causing no casualties or damage.
