Today (9-August-2018) an earthquake activity increased in south part of Katla volcano caldera. It doesn’t appear that any earthquake in this swarm reached magnitude 2,0.

It is unclear why this earthquake activity is happening at the moment. There isn’t anything unusual on harmonic tremor plots at the moment and nothing suggesting that an eruption is going to happen any time soon.

Please remember to support my work with donations. The situation is that I am getting broke this month because I’ve been paying down several things in Denmark (after I moved from Denmark to Iceland). Thanks for the support. 🙂
