Volcano three-quarters blown away by Indonesia tsunami eruption

Scientists say Indonesia’s Anak Krakatau volcano island, which erupted and collapsed a week ago triggering a deadly tsunami, is now only about a quarter of its pre-eruption size.

Anak Krakatau now has a volume of 40-70m cubic meters having lost up to 180m cubic meters since the 22 December disaster, according to Indonesia’s volcanology agency. The crater peak was brought down from 338 metres to 110 metres.

The explosion caused a tsunami that hit Sumatra and Java where more than 420 people died and 40,000 were displaced.

Experts have largely relied on satellite radar images to work out what happened to the volcano because cloud cover, continuing eruptions and high seas have hampered inspections. The centre said it would get more precise results from more visual inspections.

1. I saw this program on the Discovery channel year ago

In Alaska a wall of ice dropped into a narrow bay or fiord. The displacement of so much water so quickly by the ice caused a tsunami that lifted this boat and brought it back down again...
Very similar mechanism of the Indonesian tsunami.
