UPDATE: Australia cancels tsunami warning Tsunami warning lifted for Indonesia's Sumatra island
Authorities lifted a tsunami warning for Indonesia's Sumatra island that was issued following a major earthquake off the western part of the island, TVRI said on Wednesday quoting an official with the meterological agency.
An earthquake of magnitude 7.9 that struck off Indonesia's island of Sumatra on Wednesday killed some people, but it was not yet clear how many, an official of the country's search and rescue agency told Reuters.
"There are some who have died," said Heronimus Guru, the agency's deputy head of operations.
Indonesia issued a tsunami warning on Wednesday after a massive and shallow earthquake struck off the west coast of its island of Sumatra, a region devastated by the 2004 Indian Ocean quake and tsunami.
The warning was issued for West Sumatra, North Sumatra and Aceh after the quake of magnitude 7.9, the National Meteorolgical Agency said, but rescue efforts will be hampered by the darkness that falls early in the tropical archipelago.
The epicentre was 808km southwest of Padang, the U.S. Geological Survey said. It was 10km deep.
There were no immediate reports of damage or casualties, but the shallower a quake, the more likely it is to cause damage. USGS originally put the magnitude at 8.2, and then 8.1, before lowering it to 7.9.
"So far there have been no reports (of damage) yet," Andi Eka Sakya, an official of the National Meteorological Agency, told TVOne. "In Bengkulu (on southwest coast of Sumatra) they didn't feel it at all."
President Joko Widodo was staying overnight at a hotel in Medan in North Sumatra and was safe, palace officials said. A Medan resident said he didn't feel the quake.
Neighbouring Australia issued a tsunami watch for parts of its western coast.
Indonesia, especially Aceh, was badly hit by the Indian Ocean tsunami in 2004.
A 9.15-magnitude quake opened a fault line deep beneath the ocean on December 26, 2004, triggering a wave as high as 17.4 metres (57 feet) that crashed ashore in more than a dozen countries to wipe some communities off the map in seconds.
The disaster killed 126,741 people in Aceh alone.
Indonesia straddles the so-called ‘Pacific Ring of Fire,’ a highly seismically active zone, where different plates on the earth's crust meet and create a large number of earthquakes and volcanoes.
