Daily update for 28-February-2021 at 21:18 UTC for earthquake swarm activity in Reykjanes and Krýsuvík volcanoes

I have now switched to daily update for the earthquake swarm in Reykjanes and Krýsuvík volcanoes.

The situation in the earthquake swarm on Reykjanes peninsula in the volcanoes Reykjanes and Krýsuvík remains the same. During the last 24 hours the largest earthquakes have had magnitude of Mw4,7 and a lot of earthquakes with magnitudes above M3,0. No magma movement has been detected so far but University of Iceland – Earth science department warned that detection of magma is only limited to the first 5 km of Earth crust and any magma movement below 5 km might not be detected by seismometer. It also issued that signs of magma might be getting lost in all this earthquake activity that is currently taking place and no clear sign of magma have been detected. The whole thing can be read on Facebook here. Text in English is provided by Eldfjallafræði og náttúruvárhópur Háskóla Íslands about this.

A lot of earthquakes close to south-west end of Reykjanes peninsula also a lot of red dots on the map showing fresh earthquake activity that has been taking place in the last hour.

Some of the earthquake activity has migrated closer to the mountain Keilir. Other earthquake activity appears to be located at the same place as before. That location is close to Fagradalsfjall mountain and Krýsuvík volcano. If that changes anything when it comes to this earthquake activity I don’t know but the risk is there. Icelandic Met Office is now hoping that the earthquake swarm ends next week.

If anything major happens I’ll post new article soon as possible.

  1. I have added PayPal button again because that is what some people prefer to use instead of bank transfers. It is now possible to support my work again by using PayPal button.

  2. Has there ever been recorded such prolonged activity in this area before, either in documentation, records, or lore?

  3. There where strong earthquake swarm in this area in 1932 and in 1968. But according to experts in earthquake history the earthquake swarm now is a lot larger then past earthquake swarms in this area.
