This is a short update on the activity on Reykjanes and Krýsuvík volcanoes.

Largest earthquake in the last 24 hour had a magnitude of Mw5,2 at 08:17 UTC and this earthquake was felt over a wide area in west Iceland. Over the last 48 hours there have been 95 earthquakes with magnitude above Mw3,0. GPS is showing a lot of displacement and those information can be found here. Largest displacement has been in and around Krýsuvík and other GPS stations on Reykjanes peninsula.

Cracks have also formed in one road and other surface damage and other small damages have started to appear in buildings and roads on Reykjanes peninsula. There is going to be a storm in Iceland until early 2-March-2021. This storm is going to reduce the detection of smaller earthquakes in this earthquake swarm while it goes over Iceland.

All this information can change without warning.

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.

This is a short update at 21:19 UTC about the earthquake activity in volcanoes Reykjanes and Krýsuvík.

Earthquake activity slowed little since last update at 14:41 UTC. There are now fewer larger earthquakes taking place at the writing of this article. That has the chance of changing without warning. There seems to be new areas of activity appearing on the automatic Icelandic Met Office map. It is unclear if this is a artifact of the heavy earthquake activity in the area or a real thing is difficult to know for sure at the writing of this article.

Currently there are no signs of magma moving in both volcano systems. That might change without warning if there is a sudden change in activity. Because of how long it has been since last eruption took place in both volcanoes what happens before an eruption is unclear. What is only known from around 681 year old historical records that did survive to this day is that earthquake activity increases sharply before an eruption and does so a good while before the first eruption happens. Last eruption in Krýsuvík volcano was in the year 1340.

I am going to post next update tomorrow (25-February-2021) unless something major happens and then I’ll post a new article soon as possible.

This is about volcanoes Reykjanes and Krýsuvík.

According to new pictures from Icelandic Coast Guard. Steam has been seen from the area that had the strongest earthquakes this morning. This seems to be in a area that did not have an earlier any steam activity, this however depends a confirmation.
