A  6.9-magnitude earthquake struck eastern Indonesia on Friday at 4:09 am (UTC), the US Geological Survey reported. The undersea tremor struck at a depth of more than 600 kilometres (375 miles), about 220 kilometres south of Katabu on the island of Sulawesi.

Tremors were felt hundreds of kilometres away from the epicentre in the Banda Sea, AFP reported. No casualties or damage has been reported and no tsunami warning has been issued.

“We have not received any reports of damage so far”, Indonesia’s Meteorology, Climatology, and Geophysical Agency said, AFP reported.

Deep quakes tend to cause less damage than shallow ones.

Indonesia lies on the seismically active Pacific ‘Ring of Fire’ and thus experiences frequent seismic and volcanic activities.

A 7.5-magnitude quake followed by a tsunami, struck Sulawesi island in 2018 that left over 4,300 people dead or missing.

In 2004, a 9.1-magnitude quake struck off the coast of Sumatra that triggered a tsunami. It killed 220,000 people throughout the region, including around 170,000 in Indonesia.
