Much of the wave energy took a path away from the volcano in the same direction of the collapse - to the southwest. This resulted

fortunate that the collapse was in the southwest direction, in the direction where few people were living - towards the national park," said Prof Fritz.
"Had the collapse direction

Lessons learned from Anak Krakatau are being
