A 6.2 magnitude tectonic quake which jolted Indonesia's Aceh province Sunday morning had no potential to trigger tsunami, an official said.
"The quake was not followed by tsunami," Amran, an official of the Meteorological and Geophysic Station in Jakarta, said Sunday.
The quake occurred at 00:30 Jakarta time (1730 GMT Saturday) with epicenter at 113 km northwest Sinabang town of Aceh province and at 30 km under sea bed. But there was no report of damage or casualties.
In 2004, over 170,000 people were dead in Aceh province in northern tip of Sumatra Island after a tsunami triggered by a powerful quake devastated coastal areas of the province and others countries in southeast Asia.
Indonesia is laid at a vulnerable zone so called "the Pacific Ring of Fire" where two continental plates, stretching from the Western Hemisphere through Japan and Southeast Asia, meet that cause frequent volcanic movements.
