JAKARTA - An earthquake measuring 6.6 Richter scale jolted eastern parts of Indonesia on Sunday, but there was no potential for tsunami or no report of damages and casualty, the Meteorology and Geophysics Agency said here.

The quake jolted at 18:52 p.m. local time (1152 GMT) with epicenter at 222 km northeast Maluku Baratdaya of Maluku province and with the depth at 131 km under sea bed, an official of the agency told Xinhua by phone.

"The center of the quake was too deep that the shakes could not be felt," the official said.

Indonesia sits on a vulnerable quake-hit zone so called "the Pacific Ring of Fire".
