Slight increase in earthquake activity in Öræfajökull volcano

Today (1-August-2018) there seems to be a minor increase in earthquake activity in Öræfajökull volcano. What has also happened is that magnitude of earthquakes today has been slightly larger then in a normal week. Few magnitude 1,0 and larger and at least one magnitude 1,5 earthquake have happened so far.

Current rate of earthquakes have dropped down to 50 earthquakes a week from earlier 100 earthquakes a week. This change might be normal for Öræfajökull volcano since this magma intrusion seems to be moving slowly inside the volcano. Regular earthquake activity continues to happen and there is no sign that is changing at the moment.

    I found this online about the 1362 eruption. It is 100 pages long and I have not managed to get through it all as yet but it may be of interest to some. Somewhere in the article it says that there were six volcanic eruptions in Iceland at this time.

    Looks like a bit of a swarm occurred at Katla this morning
