On 18-November-2016 a minor earthquake swarm took place in Katla volcano. This was a minor earthquake swarm with largest magnitude around 2,5. At the moment the earthquake activity appears to have ended, it might resume at later time.
The earthquake activity is in a area that had a minor eruption in the year 1999. There has not been a major eruption in this part of the caldera for a long time according to historical data. It is possible that last major eruption in this area took place in the year 1245, but that eruption is not properly documented due to old age of the historical documents.
Please remember to support my work. It helps me to do my work and write about earthquakes and volcanoes when something is going on in Iceland. Thanks for the support. 🙂
