A strong earthquake with a magnitude of 6.1 on the Richter scale has jolted islands in north-eastern Indonesia on Saturday but no immediate damage or casualty has been reported and no tsunami alert has been issued.
The quake was centered 155 km (95 miles) southeast of Labuha in the North Moluccas at a depth of about 30 km (20 miles) and occured at 4:41 p.m. local time,according to the local Meteorological and Geophysics (BMG) agency.
The BMG said the quake did not trigger a tsunami. It was the latest of a series of earthquakes to jolt Indonesia in recent months.
Indonesia is located on a series of geological fault lines, making it vulnerable to frequent earthquakes and volcanic eruptions.
