The country's meteorology, climatology and geophysics agency said the tremor of the quake did not trigger a tsunami.

In the hardest-hit Talaud Island, the tremor was felt strongly, but did not trigger panic among local residents, said Jabes Linda, head of the operational unit of the disaster management and mitigation agency in the district.

"We have checked the risks in each sub-district, and so far there were no reports of damage or casualties from the quake," he told Xinhua.

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