Earthquake activity in new location in Reykjanes volcano

Today (10-May-2022) during the night an earthquake swarm started in a new location in the volcano Reykjanes. This location is about 11 km south of Keflavík International Airport, it is also close to a village named Hafnir. Largest earthquakes in this swarm had a magnitude of Mw3,0 and Mw3,2. The second earthquake was felt in the area. A lot of smaller earthquakes also took place at this location.

This earthquake activity suggests that a new magma injection is taking place in this location. The chance of an eruption is in my view high for this location, when it might happen is impossible to know. There is a old lava field in this area and some say it might be from last ice age. I am not sure on the exact age of this lava field, the crater that created this old lava field has eroded away by the ocean centuries ago.

Earthquake activity in Tjörnes Fracture Zone

This earthquake activity is normal for this part of Tjörnes Fracture Zone. It is not possible to know what is going to happen next in this activity if anything and it might just stop.
