Indonesia: Magnitude 6.7 earthquake strikes Indonesia's North Sulawesi

An earthquake measuring 6.7 on the Richter scale struck Indonesia`s North Sulawesi province, but did not trigger a tsunami, the country`s meteorology and geophysics agency said.

The agency initially said the quake`s magnitude was originally measured at 6.9 magnitude, Said Kristyawan, an official in charge at the agency, told Xinhua on Monday morning.

There were no preliminary reports of damages or casualties resulted from the earthquake, he said.

The quake struck at 10.23 p.m. on Sunday with the epicenter at the depth of 117 km under the sea bed, 280 km north Melonguane sub-district of Talaud islands district, the official said.

"The epicenter is located in the deep sea, hence it did not trigger a tsunami. So far, there were no reports of the impact of the quake," he said.

The intensity of the quake was felt in Tahuna district and Siau island.

Indonesia is frequently hit by earthquakes as it lies on a vulnerable quake-hit zone of "the Pacific Ring of Fire".
