"There is no potential for triggering tsunami. So that, no tsunami warning was issued," he told Xinhua by phone.
The jolts of the quake was felt strongly in nearby Lombok island, the official said.
The intensity of the quake was felt at IV MMI (Modified Mercalli Intensity) in southern Lombok, eastern Lombok and Mataram city of Lombok Island, and III to IV MMI in Denpasar city of Bali island, and III MMI in Sumbawa district, Bima, Dompu and North Lombok of Lombok Island, he said.
