64 hectares of Krakatau volcano collapsed

The Indonesian meteorological service has confirmed that Saturday's tsunami was caused by the collapse of part of the Anak Krakatau volcano in the Sunda Strait.

Anak Krakatau, meaning child of Krakatau, spits ash and lava for months. About 64 hectares of the southwestern side of the volcano have collapsed. 'This caused a landslide under water and eventually the tsunami,' said Dwikorita Karnawati, head of the meteorological department, and several scientists had said before that the most likely cause of the tsunami was the collapse of part of the volcano.
