Ongoing earthquake swarm in Öræfajökull volcano (update 29-June-2018)

There is currently ongoing earthquake swarm in Öræfajökull volcano. This earthquake swarm started on 26-June-2018 with the magnitude 3,1 and it has been mostly ongoing since then. All earthquakes are minor in the volcano at the moment. A magnitude 2,1 earthquake happened outside the volcano (but those earthquakes appears to be connected to it) and suggest crustal stresses are changing at the moment at expectational speed (my view).

What also appeared today is a earthquake swarm in the side of Öræfajökull volcano. If this earthquake activity continues it is worrying as it suggests that an eruption might happen in Öræfajökull volcano side and that might be a major issue if a eruption vents opens up in such area. Since this is close to Road 1 and warning time might be limited or close to none in worse case. This type of activity warrants more monitoring in my view.

  1. Mighty intriguing!
    She’s the one that erupts suddenly and with a lot of force..
    Also potential VEI 5 right?

    1. The eruption in 1362 was VEI=5. The eruption in 1727 was VEI=4. Both lasted several months (more than 3 months). More information is on Global Volcanism Program website (link in the article).

  2. Looks like small EQ’s picking up again at the side of Öræfajökull, would you say it won’t be long till another yellow warning gets put out?
