This is a short update on activity in Reykjanes and Krýsuvík volcanoes. This update is written at 19:28 UTC.
The activity today (25-February-2021) has been mostly just minor earthquakes. Largest earthquakes today had a magnitude of Mw3,5 but this number can still change. In the last 24 hours over 2500 earthquakes have been recorded by Icelandic Met Office according to the news.
Steam has been confirmed close the parking lot close to Keilir mountain on Reykjanes peninsula. This area did not have steam before the Mw5,7 earthquake yesterday (24-February). It is unclear that is going on in that location. There continues to be high risk for a earthquake with magnitude Mw6,0 to Mw6,8 on Reykjanes peninsula because of this earthquake activity.
I’ll post update soon as possible if anything happens.
The ongoing swarm is impressive. Can this be felt in Reykjavik?
The larger quakes (at least 3.0 but certainly 4.0 or above) can usually be felt in Reykjavík
Just the largest earthquakes. If a magnitude Mw2,0 earthquake happens close to Reykjavík it can be felt but normally that doesn’t happen.
Jón, do you have any ideas on the high hydrogen sulphide emissions, or the swarm that has got going in the last hour?
I just have the information I’ve seen in the news.
