BANGKOK, April 7 (Xinhua) -- Thailand issued tsunami alert Wednesday following a 7.2-magnitude earthquake in Indonesia's northern Sumatra.
The National Disaster Warning Center warned people in coastal areas to evacuate to a safe place, saying there was a high risk of a tsunami on the Andaman Coast.
A major 7.8-magnitude earthquake hit Indonesia's northern Sumatra early Wednesday, the U.S. Geological Survey reported, triggering a local tsunami watch.
Indonesia's Meteorology and Geophysics Agency reported the earthquake at a magnitude of 7.2.
Since the Indian Ocean tsunami in 2004, Thailand has installed a high-tech warning system.
