Earthquake activity in Grímsfjall volcano

Early this morning at 06:53 UTC an earthquake with magnitude of Mw4,3 took place in Grímsfjall volcano. This is the largest recorded earthquake in Grímsfjall volcano since recording started in 1991. This happened soon after a glacier flood started from Grímsfjall volcano lake. This is a minor glacier flood.

Experts are expecting an eruption from Grímsfjall volcano. However, it is my personal view that no eruption is going to happen during this flood like last time. The reason being that Grímsfjall volcano has entered different type of eruption cycle. Start of that eruption cycle was in the May eruption in 2011. Why that is I don’t know.

  1. Thanks for the update on Grímsfjall.

    What do you think is happening on Reykanes peninsula? Will there be an eruption in the coming days?

    1. There’s going to be an eruption from Svartsengi volcano soon. Last time it took eight days from maximum inflation until an eruption started. That might not apply now, but seems to be a good basic rule to go by.
