A 6.3-magnitude quake hit Indonesia's eastern North Maluku province today. The local Meteorological and Geophysics agency said, the quake struck underwater at a depth of 105 kilometres and 254 kilometres north-east of Ternate island at 4:16 pm (local time). However, there was no immediate reports of damage or tsunami alert. Indonesia sits on the Pacific Ring of Fire, where the meeting of continental plates causes high volcanic and seismic activity.
