Strong earthquake swarm in Reykjanes volcano

Yesterday (12-April-2022) at 21:21 UTC an earthquake swarm started with a magnitude Mw3,9 earthquake. There is a chance there have been a swarm of smaller earthquakes in last few weeks in this area. Since there has been almost always on earthquake swarm activity on this part of Reykjanes peninsula in recent months. The largest earthquake was felt over a wide area in south and west Iceland. Over seven earthquakes with magnitude Mw3,0 have taken place, accurate number is difficult to know for sure at the moment.

The activity now is happening in a volcano named Reykjanes. Last eruption might have happened last time in the year 1831 but that is difficult to know for sure. At the writing of this article around 264 to 280 earthquakes have been recorded by Icelandic Met Office. This number changes every few minutes because the earthquake swarm is strong and ongoing currently. Earthquake activity seems to be increasing at the writing of this article. This situation can change quickly. I am seeing clues that this earthquake swarm is because of magma movement. I think it might result in a eruption, but that is impossible to know for sure now.
