The Indonesian government has issued a tsunami warning after an earthquake with a magnitude of 7.3 struck the island of Sumatra at 12:37 AM Indonesian time. The U.S. Geological Survey says the epicenter was off the island's west coast. There are no reports of injuries.
Despite the quake's strength, the Pacific Tsunami Warning Center quickly issued a statement saying "a destructive widespread tsunami threat does not exist". The center based its projection on historical quake and tsunami data.
But it warned local agencies within 100 kilometers of the epicenter to watch for a local tsunami that could strike the Sumatran coast.
On December 26, 2004, an earthquake with a magnitude of 9.1 rocked Sumatra's west coast, as CNN reminds us. It triggered a powerful tsunami which killed people as far away as Africa. About a quarter of a million people died in 14 countries, with the most devastating death toll in Indonesia's Banda Aceh province.
