A magnitude 6.2 earthquake struck the island of Sumbawa in the Indonesian archipelago on Friday, the United States Geological Survey (USGS) said.
The tremor hit about 33 kilometers south of Tolotangga, about 1,350 kilometers from capital Jakarta. There was no tsunami warning after the earthquake, which was deep at 72 km.
There were no reports of death or injury though people evacuated from their houses. The earthquake hit about 6:30 in the morning.
The earthquake was felt in the tourist island of Bali as well, the National Disaster Mitigation Agency said. "The earthquake was quite long. Most people had just woken up and they started running out from their homes. My family and I also ran away because we were afraid," a resident of the island of Sumba told AFP.
This is the second major earthquake to hit the archipelago after the December 7 tremor of magnitude 6.5 in Aceh province that killed more than 100 people.
Indonesia sits on the seismically active Pacific "Ring of Fire", where tectonic plates collide, and the region experiences frequent earthquakes. The 2004 earthquake and tsunami had killed more than 170,000 people in Indonesia.
