Major earthquake in Indonesia triggers tsunami warning
Indonesia issues tsunami alert after powerful 7.9 magnitude earthquake struck off the coast of Sumatra island.
Indonesia
has issued a tsunami warning after a powerful and shallow 7.9
magnitude earthquake struck off the west coast of the island of
Sumatra.
The quake struck at a depth of 10 kilometres on Wednesday, triggering a tsunami alert for parts of Sumatra, including West Sumatra, North Sumatra and Aceh, the local BMKG quake monitoring agency said.
There were no immediate reports of damage or casualties but the shallower a quake, the more likely it is to cause damage.
The US Geological Survey originally put the magnitude at 8.2, and then 8.1, before lowering it to 7.9.
"Earthquakes happen very regularly in these areas," said Al Jazeera's Step Vaessen, reporting from Jakarta. "People run to higher ground when this happens.
"So far, there are no reports of deaths. We're waiting for the authorities to lift the warning, which we expect to happen within the next hour," our correspondent said.
Indonesia, badly hit by the Indian Ocean tsunami in 2004, 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.
The 2004 tsunami killed 230,000 people in a dozen countries. Most of the deaths were in Aceh province.
