AKIPRESS.COM - The scale of the dramatic collapse of the Indonesian volcano that led to last Saturday's devastating tsunami in the Sunda Strait is becoming clear, BBC reports.
Researchers have examined satellite images of Anak Krakatau to calculate the amount of rock and ash that sheared off into the sea.
They say the volcano has lost more than two-thirds of its height and volume during the past week.
Much of this missing mass could have slid into the sea in one movement.
It would certainly explain the displacement of water and the generation of waves up to 5m high that then inundated the nearby coastlines of Java and Sumatra.
Indonesia's disaster agency says more than 400 people are confirmed dead with 20 or so still missing. In excess of 40,000 have been displaced.
