An earthquake with magnitude of 6.4 on the Richter scale rocked East Timor and eastern parts of Indonesia on Saturday, no immediate reports of damages or casualty, Indonesian meteorology agency and health ministry said here. The quake struck at 18:21 time (10:21 GMT) with epicenter at 81 km northeast Dili the capital of the country and at 10 km under sea bed, an official of the agency Diana Rahayu told.

The center of the quake was closer to Wetar Island of Maluku province in eastern parts of Indonesia, the official said. Head of Crisis Center of Indonesian Health Ministry Rustam Pakaya said there were no report of damage or casualties in Dili and eastern parts of Indonesia bordering with East Timor. Both Indonesia and East Timor are located in a vulnerable zone called “the Pacific Ring of Fire” where two continental plates, stretching from the Western Hemisphere through Japan and Southeast Asia, meet that cause frequent tectonic movements.

Hundreds of people have fled their homes after the Mount Egon volcano erupted on the island of Flores on Tuesday evening. There are no reports of damages or casualties according to Indonesia’s volcanology and disaster management agencies on Wednesday. Head of the volcanology agency Surono said that Mount Egon in the Sikka regency of East Nusa Tenggara province spewed lava at 22:15 p.m. local time on Tuesday and resulted smoke up to 4,000 meters high.

Surono predicted that more explosions would follow as the Tuesday evening’s explosion was not categorized as the major explosion. “I think there will be more bigger explosions. Our team has already been in the scene to closely monitor the volcano activities,” he said. Indonesian Disaster Management Agency official Mounique said that over 600 people living on the slope of the mountain had been evacuated.

Mount. Egon is part of the country’s 129 active volcanoes, which 66 of them are located in high-density population areas, Java and Sumatra islands, according to the volcanology agency.
