The 8.2-magnitude quake off Sumatra badly damaged buildings along the coast and could be felt in at least four countries, with tall buildings swaying as far as 1,200 miles away.
It was followed by a series of powerful aftershocks, the strongest of which registered at a magnitude of 6.6 and triggered a second tsunami alert for Indonesia, the meteorological agency reported.
At least seven people were killed in three Sumatran towns, Social Affairs Department official Felix Valentino told the news portal detik.com.
A wave of up to 9 feet was reported to have struck the city of Padang about 20 minutes after the initial quake, said Suhardjono, an official with Indonesia's meteorological agency, who goes by only one name.
