Yesterday (19-June-2019) an earthquake swarm took place south-east of Bárðarbunga volcano. This area of Bárðarbunga volcano has been active since end of the eruption in February 2015 and possibly earlier than that. Last eruption in this area took place in with a start in February 1726 (+- 30 days) and ended in May 1726 (+- 30 days). More eruptions might have taken place at this location without being known or detected by people in the past.

The depth of this earthquake swarm is considerable. Deepest earthquake recorded had a depth of 30,4 km and it is a possible that might be an error or poor location, other earthquakes recorded had a shallower depth. The crust in this location is up to 45 km thick according to measurements. It is not possible to know if this earthquake activity is going to result in a eruption. If an eruption happens it might happen without any warning and not of lot of earthquake activity before it happens.
