All traffic to Askja volcano forbidden due to a large landside yesterday (22-July-2014)

According to Icelandic Meteorological Office, a large landslide fell yesterday (22-July-2014) around midnight in Askja volcano, the landslide did go into Askja lake creating a flood wave that was 100 to 200 meters high. It did reach the other end of the crater lake and did flow over its edge, some water did go into Víti crater. This landslide took place in south part of the Askja lake crater (best information I have at the moment). Harmonic tremor was detected following this events, it was recorded for 20 minutes according to news reports (no image since Askja harmonic tremor plot image is missing in IMO website).

A cloud was seen following this landslide, it is not clear if it was steam or just loose dirt material moving up into the air. Early estimates into this landslide are that around 24 million cubic meters of material did come down with this landslide, part of it ending in Askja lake and raising the water levels in Askja lake some two meters (early estimates). Until this matter has been checked by scientist and Almannavarnir in Iceland, all traffic to Askja volcano is forbidden. There is also a risk of more landslides taking place in Askja volcano, since the soil where the landslide took place might not have settled yet. It is highly dangerous to go there under the current conditions and I urge anyone not to go there due to how dangerous this area now is.

Update 1: Image of the landslide can be found here.

I am going to post more information about this once I have more details on this event.
