It is impossible to know if this is going to result in any eruption. This inflation however seems to have resulted in earthquake activity in Askja volcano. Most of the earthquakes so far have been minor in magnitude.

  1. Very interesting. If this one becomes active during the colder months (which is quickly approaching), it would be hard viewing, if anything were to be setup for that. But these volcanoes like to take their time, so many months probably if this type activity continues. Is this the explosive type, or more effusive?
