A powerful underwater earthquake struck western Indonesia on Sunday, injuring four people as they tried to flee, officials said. Indonesia's meteorological and geophysics agency said no tsunami warning was issued. The U.S. Geological Survey said the quake registered magnitude 6.7, after initially measuring it at 7.0. It struck at 2:38 p.m. (0738 GMT) and was centered at a depth of 28 miles (45 kilometers) under the Indian Ocean seabed, about 70 miles (110 kilometers) west-southwest of the city of Padang on Sumatra island, it said. Four people were injured as they fled in Padang and a house was damaged, said Ade Edward, a local government official was quoted as saying by The Associated Press.
