A powerful, 7.5-magnitude earthquake hit the Indonesian island of Sulawesi on Friday, September 28, triggering a tsunami and leaving more than 1,400 dead. Tens of thousands have been displaced, and the death toll is expected to rise.

Conditions in the devastated area are grim, with food and water supplies running low and few buildings sturdy enough to offer safety from aftershocks. Disaster officials say the inability to access the worst-affected areas has hampered recovery efforts.
