An earthquake of magnitude 6.2 struck off the Indonesian island of Lombok today, the United States Geological Survey said, but there were no immediate reports of casualties or damage.
The earthquake, which hit 234 km (145 miles) south of Lombok, at a depth of 29 km (18 miles), also briefly startled tourists on the Indonesian resort island of Bali.
The quake was strong, with tremors lasting for three to four seconds, but did not trigger a tsunami alert, said Sutopo Purwo Nugroho, a spokesman of Indonesia's Disaster Mitigation Agency (BNPB).
"The quake went on for quite a while," said a witness in Lombok. "People ran out from houses in panic."
In December 2004, a strong earthquake off the Indonesian Island Sumatra had triggered a tsunami that killed 230,000 people in 14 countries.Indonesia was the worst hit, followed by Sri Lanka, Thailand and India.
