A magnitude 5.3 earthquake rocked North Maluku province on Monday but there was no immediate report of casualties or material damage. The quake which struck at 04.07 p.m. was centered 253 km northeast of the North Maluku provincial capital of Ternate at a depth of 10 km, ANTARA quoted the Meteorology, Climatology and Geophysics Service in Jayapura as saying. Indonesia sits on the Pacific "Ring of Fire" where the meeting of continental plates causes high volcanic and seismic activity. North Maluku lies at the meeting point of the country's two main chains of volcanoes.
