An unusual event occurred at Askja volcano at 23:24 on the 21st July 2014, comprising a major rockslide on the southeastern part of the caldera wall, which triggered a tsunami in Lake Öskjuvatn. A white cloud was also observed over the Dyngjufjöll mountains. Initial observations suggest wave heights from the tsunami reached in the order of 40-50 m and spilled over the northeast wall into the adjacent Viti Lake. This area is currently closed for safety reasons.
