Hundreds of buildings were damaged by the tremors
Another powerful earthquake has hit the Indonesian island of Sumatra, a day after the world's strongest tremor so far this year caused extensive damage.

At least nine people were killed and many buildings damaged. But the full scale of the impact has yet to emerge.

Tsunami warnings were repeatedly issued and lifted, as many people ran inland fearing a repeat of the 2004 tsunami.

Thursday's magnitude-7.8 quake hit the same area in southern Sumatra as the tremor of 8.4 on Wednesday.

"Many buildings collapsed after this morning's [Thursday's] quake. We're still trying to find out about victims," Padang Mayor Fauzi Bahar told a local radio station.

Casualties appear to be lower than first feared, but officials warn that bad communications may be hiding the scale of the impact.
