Five people died and several were injured after a powerful undersea quake rocked Indonesia's heavily populated Java island, triggering a brief tsunami warning, the national disaster agency said Saturday.
Indonesia issued a tsunami warning within minutes of the 6.8-magnitude quake on Friday night. The warning last two hours and sent people living along the coastline fleeing to higher ground.
The shaking was felt in Indonesia's capital city of Jakarta, 240 miles from the epicenter, prompting people to run out of their homes.
Thousands residents of Pasaran Island, Bandar Lampung fled to the Lampung Governor's office area, following the natural disaster.
On Saturday, authorities said a panicked 48-year-old woman had died of a heart attack as the strong quake rocked the region.
The USGS said the 6.9-magnitude quake struck just after 8 a.m. ET.
The agency says at least 113 houses and buildings were damaged and about 1,050 people fled to temporary shelters.
This lies along the Sunda fault, where researchers have long found a potential for a megathrust quake, Wibowo said, referring to a very large natural disaster that occurs in a region where one of the earth's tectonic plates is thrust under another.
Indonesia's 17,000 islands are prone to earthquakes because the country straddles the Pacific Ring of Fire, an arc of fault lines and volcanoes that causes frequent seismic upheavals.
Last year, thousands of people were killed when a tsunami hit Sulawesi Island.
On December 26, 2004, a devastating 9.1-magnitude natural disaster struck off the coast of Sumatra and triggered a tsunami that killed 220,000 across the Indian Ocean region, including around 170,000 in Indonesia.
