JAKARTA: A 6.1-magnitude earthquake struck off the coast of Indonesia's remote Maluku islands Thursday, the United States Geological Survey said, but no tsunami warning was issued. The strong quake hit at a relatively shallow depth of 31 kilometres (20 miles), about 127 kilometres southwest of the city of Ternate. Shallower quakes tend to cause more damage, but there were no immediate reports of casualties.

"It was a decent shake, but people weren't panicking," said Ternate resident Nasarudin Amin.

"There are warnings about potential aftershocks."
