Earthquakes in Askja volcano. Askja is located to the north of Vatnajökull glacier and the lake is round in shape on this map. Marked by the orange dots on it. Copyright of this image belongs to Icelandic Meteorological Office.

This activity is part of an progress that started in Askja volcano back in the year 2010. So far this has not lead to any eruption. But it has created some odd changes. Along one was that Askja lake was ice free last year (winter 2012). The reasons for that are still not known to me.

Uncertainty level declared on Hekla volcano

Uncertainty level has been declared on Hekla volcano due to strange earthquake activity in it for the past week or so. But in total of seven earthquakes where recorded in Hekla volcano at the depth of 11 to 12 km. This is highly unusual for Hekla volcano. People are advised against going up to Hekla volcano while uncertainty level is in force. It is also dangerous to be too close to Hekla volcano. Since if an eruption starts, it is going to start without any warning at all.

I am going to post updates on Hekla volcano as needed if anything happens. It is possible to watch activity live from Hekla volcano on my geophone page here. But I have a geophone located about 16 km away from Hekla volcano. List of web cameras that I know of are online and focused on Hekla volcano can be found here. Update 1: Web camera that is showing Hekla volcano (pictures) can also be found here.
