JAKARTA - A moderate 5.6-magnitude earthquake struck off Indonesia's West Java province Wednesday but there were no immediate reports of damage and no tsunami warning was issued, officials said.

The quake struck at 10:17 am local time, 214 kilometres southwest of Tasikmalaya at a depth of 66 kilometres, the meteorology and geophysics agency said.

Indonesia sits on the Pacific "Ring of Fire," where the meeting of continental plates causes high volcanic and seismic activity.

A 7.6-magnitude quake that struck Sumatra island on September 30 killed more than 1,000 people.
