JAKARTA, Aug. 6 (Xinhua) -- A shallow undersea quake measuring 6.2 on the Richter scale rocked Maluku province in eastern parts of Indonesia on Wednesday, and a tsunami warning seemed unlikely, the Meteorology and Geophysics Agency official said.
Meanwhile, the USGS put the magnitude of the quake at 6.1.
The quake struck at 18:45 p.m. Jakarta time (1145 GMT) with its epicenter at 200 km northeast Maluku Barat Daya and a depth at 10 km under sea bed, the official said.
"The quake shakes were not felt and we did not issue a tsunami warning," she told Xinhua over phone.
Indonesia is prone to quake as it sits on a zone vulnerable to quake, known as "the Pacific Ring of Fire."
