Today (24-June-2019) at 13:09 UTC, 13:18 UTC and 13:55 UTC three strong earthquakes took place in Bárðarbunga volcano. The earthquake at 13:09 UTC has registered magnitude of mb4,5 at EMSC (information here). The earthquake at 13:55 UTC also has the magnitude of mb4,5 at EMSC (information here). Icelandic Met Office has the earthquake at 13:09 UTC at magnitude Mw3,3 and the earthquake at 13:55 UTC at magnitude Mw4,1. The earthquake at 13:18 UTC has a magnitude of Mw3,4. Smaller earthquakes have followed the largest earthquakes.
This earthquake activity is because of inflation in Bárðarbunga volcano. Since Bárðarbunga volcano continues to be in a inflation stage this earthquake activity did not result in a movement of magma or an eruption. Two of the earthquakes were in the regular location (central caldera and north-east part of the caldera) and the earthquake at 13:09 UTC took place outside the caldera and in north-west part of the volcano. This is slightly unusual based on earlier earthquake activity in Bárðarbunga volcano. Last strong earthquake in Bárðarbunga volcano was on 19-June-2019 and this a short time between strong earthquakes in Bárðarbunga volcano. This doesn’t seems to be unusual activity.
