Krakatau volcano (Sunda Strait, Indonesia): high seismic activity, new eruption in progress?Tuesday Oct 11, 2011 10:11 AM |
Øystein Lund Andersen sent a report about his recent visit to the Krakatau obsvervation post on West-Java last weekend: "As you may know Krakatau have seen a huge increase of Volcanic quakes, shallow earthquakes. Before the earthquake swarm started (before Sep 30) the rate was around 80-200 per day. When I visited the observatory the rate was around 5000, even 6000 this sunday. The people at the observatory claim they have never seen a rate like this from Krakatau, and question themselves what will come? On sunday they went to Krakatau to position two more seismograph to get more clearer data to work on. Im really intrested in the subject, and I have posted a video of of the seismograph taken on saturday 8th october. See it here. How would you interpret this, is it reasonable to think that something bigger than the usual strombolian eruptions to occur?"
