Over the past few days scientists from Icelandic Meteorological Office and University of Iceland, geology department have been studying the massive landslide in Askja volcano. The area is considered unstable as is and might remain unstable for the next year and even longer. Risk of new landslide in Askja is not higher now than normal, but even so the walking paths around Askja lake are going to remain closed due to changes that took place when the flood wave hit the volcanic crater coastline following the landslide.
It remains unclear why this landslide took place. It does not seem that wet soil is the reason for this, as was originally thought. Some speculation have been that this might be due to increased hydrothermal (hot springs) activity in Askja volcano. Nothing has yet been proven on what did cause this large landslide. There have also been news items that a earlier landslide around the same size might have taken place in Askja volcano in the years 1902 to 1960 (exact date is not known). Current size estimates are that the landslide is around 50 million cubic meters in size and around 700 meters wide at the top. More research is going to give more details on this landslide in the future. The seismic signal and following harmonic tremor that was detected following this landslide has a detailed analyse here on Icelandic Meteorological Office website.
If more landslides do happen in Askja volcano I am going to publish that information soon as possible. If more information is going to be published I am going to post them soon as possible.
Donations: Please remember to donate to support my work. Due to my move to Iceland in December I have updated the information here. Please take a note of the changes that are going to take place in January 2015. Thanks for the support.
