PanARMENIAN.Net - A 6.4-magnitude earthquake struck off the west coast of Indonesia's Sumatra island on Wednesday, sending terrified residents fleeing from homes and buildings, according to Reuters.
One man collapsed and died of shock while rushing out of his home, authorities said.
The quake, at a depth of 22 kilometers (14 miles), struck around 07:30 am (0030 GMT), some 34 kilometers northwest of Sinabang, capital of Simeulue - a small, remote island off Sumatra's west coast, the US Geological Survey (USGS) said.
Residents of Sinabang said violent shaking was felt for about a minute and had caused an electricity blackout.
National Disaster Agency spokesman Sutopo Purwo Nugroho said one man died while fleeing from his home on the island, which has a population of about 80,000. "A man on Simeulue died of shock. He had a history of high blood pressure and was rushing out of his home when he collapsed and died," Nugroho said.
Local media and Indonesia's meteorology agency said there were no immediate reports of significant damage or other casualties directly related to the quake.
The agency said the quake occurred in the sea off Simeulue, but did not issue a tsunami warning. It said slight shaking was felt in the city of Banda Aceh, about 360 kilometres from Simeulue.
The Australian Bureau of Meteorology said the Indonesian quake posed no tsunami threat to Australia.
The USGS initially reported a 6.6-magnitude quake, but downgraded the intensity to 6.4 - the same strength as Indonesia's meteorology agency reported.
Indonesia sits on the Pacific "Ring of Fire" where continental plates collide, causing frequent seismic and volcanic activity.
