A strong 6.7-magnitude earthquake has shaken Indonesia, the U.S. Geological Survey reported early on Monday morning, but there were no reports of damage or casualties initially, Reuters reported.
The USGS said the quake occurred 10 miles (8 km) north-northwest of Raba, Sumbawa, Indonesia, at a depth of 11.4 miles (18 km) at 3:41 a.m. local time (1941 GMT Sunday).
There was no reported tsunami warning.
An official from Indonesia's meteorology agency told Reuters there had been reports of panic in Mataram, the capital of Lombok, where a strong tremor was felt.
"We haven't got any reports of damage or injuries. Communications are not cut," said Hardiatno from Indonesia's meteorology agency.
Indonesia is situated in an area of intense seismic activity known as the "Pacific Ring of Fire".
