Jakarta, Aug 19: A strong earthquake of magnitude 6.5 hit Sumbawa Region in Indonesia at 9:40 am IST, the US Geological Survey said. There are no immediate reports of damage or injuries.
Witnesses said the earthquake was felt strongly in east Lombok.
This comes just weeks after a quake which killed more than 460 people.
The tremor was centered west-southwest of Belanting town in East Lombok, the USGS said, at a relatively shallow depth of seven kilometres (four miles). Residents said the quake was felt strongly in East Lombok.
The tremor was also felt in the island's capital Mataram and on the neighbouring resort island of Bali.
Indonesia sits on the so-called Pacific "Ring of Fire" where tectonic plates collide and many of the world's volcanic eruptions and earthquakes occur.
