This earthquake activity suggests that magma is on the move in Askja volcano. Nothing however suggests that Askja volcano is close to an eruption of any type. Current situation seems to have been created by the fact Bárðarbunga volcano 2014 eruption almost started an eruption in Askja volcano by injecting magma into it. That didn’t happen because the magma stopped before reaching Askja volcano magma chambers. That interaction might have changed the situation inside Askja volcano magma chambers resulting in the earthquake activity that is now appearing in Askja volcano.
