In pictures: Sumatra quake

The search continues for survivors on the Indonesian island of Sumatra where Sunday's massive earthquake left many dead and caused widespread destruction. The south-west of the island was hardest hit - with many buildings totally destroyed, and those still standing left dangerously unstable.

Improvised hospitals have been set up to treat the injured

Continuing aftershocks forced people to flee their homes

Roads and other links have been cut, hampering rescue efforts

Many houses collapsed entirely, reduced to piles of rubble

Rescuers expect their search to unearth further victims
