导读:印尼最西端的亚齐省附近海域11日发生里氏8.6级地震后,当地居民纷纷冲出房屋,急寻避难场所。据报道,印尼邻国新加坡、泰国和印度均有震感。位于夏威夷的太平洋海啸预警中心以及印尼当局均已发布海啸预警。美国地质调查局最初公布震级为里氏8.9级,后修订为里氏8.6级。

A tsunami watch declared after two major earthquakes off the coast of Indonesia's Aceh province has now been cancelled, the Pacific Tsunami Warning Center (PWTC) says.

Two hours after the quakes - one with a magnitude of 8.6, the other measuring 8.3 - the centre says "the threat has diminished or is over for most areas".

The alerts caused panic as people fled buildings and made for high ground.

There have been no immediate reports of damage or casualties.

India, Thailand and Sri Lanka have also lifted their own tsunami warnings.

The region is regularly hit by earthquakes. The Indian Ocean tsunami of 2004 killed 170,000 people in Aceh alone and some 250,000 around the region.
 
'Vigilant'

The US Geological Survey (USGS), which documents quakes worldwide, said the first Aceh quake was centred at a depth of 33km (20 miles), about 495km from Banda Aceh, the provincial capital.

It was initially reported as 8.9 magnitude but was later revised down to 8.6 by the USGS. Quake officials said a tsunami had been generated and was heading for the coast of Aceh.

The BBC's Karishma Vaswani in Jakarta says there were reports of the ground shaking for up to five minutes.

A PTWC alert said that sea level readings indicated a tsunami was generated and that it "may already have been destructive along some coasts," without specifying where.

A Thai disaster official said a 10cm wave had been recorded on Koh Miang island, off Phang Nga.

Earlier, Indonesian President Susilo Bambang Yudhoyono said the authorities were remaining "vigilant", despite the lack of tsunami reports.

"Our warning system is working well, and I have ordered the national relief team to fly immediately to Aceh to ensure the situation is under control and to take any necessary action," he said.

A few hours later, the PTWC renewed its warning after a major aftershock measuring 8.2 struck 16km (10 miles) beneath the ocean floor and 615km from Banda Aceh.

An AFP correspondent in Banda Aceh said the second aftershock lasted four minutes.

The PTWC issues advisory alerts across the region, which state authorities can use to issue their own emergency procedures. Indonesia straddles the Pacific Ring of Fire, a zone of major seismic activity.
