The tsunami arrived without warning, caused by a landslide when the Anak Krakatau volcano erupted.
Rescuers are trawling through towns and beaches, searching for survivors, while the death toll is expected to keep rising.
More than 1,000 people are injured, and many are waiting in temporary shelters and hospitals.
The Medecins Sans Frontiers is assisting on the ground.
