Krakatau Vulkan: News & Updates

Krakatoa volcano update: What caused the tsunami?

Monday Dec 24, 2018 14:58 PM | VON: T

The triggering cause of Saturday's tsunami is still being discussed. A common and likely interpretation is a landslide, which could have been caused by either, or a combination of:
- a slide simply caused by the weight of rapidly accumulated new lava material on the flanks, both above and below water
- a sudden lateral blast caused by an explosion as magma rising could not be released quickly enough from the established summit vent.
It is also unclear how much of the island disappeared by the initial event and how much crumbled away during the following erosion by eruption and adjustments by gravity.
A sketch published on twitter illustrated the version implying a larger lateral blast:
This picture explains how the Indonesia volcanic tsunami was generated. Many volcanic eruptions cannot generate tsunami. The Krakatoa volcanic mass should have been very large; probably a volume of a few kilometers cubed #IndonesiaTsunami #Krakatoa #Tsunami #Indonesia pic.twitter.com/lQCx3yrAgg— Dr Mohammad Heidarzadeh (@Mo_Heidarzadeh) December 23, 2018


A smaller version - without flank collapse, fortunately (or the video and people involved would not exist any more) - was filmed in Oct by Ronny, one of our participants on the Krakatau Volcano Special tour: (you have to watch carefully where the eruption starts):
