Icelandic Met Office confirms magma is rising to the surface

Icelandic Met Office has confirmed that magma is now rising to the surface in the area of Sundahnjúkar crater row. This does not seems to be connected to Svartsengi magma (Reykjanes volcano) dyke intrusion. How much magma and what volcano it is connected is unclear at the writing of this article. This might not be connected to Fagradalsfjall volcano also. If that is the case, it means this either a new unknown volcano at this location or rift eruption not connected to any volcano. It is going to take a while to get an answer to that question once the eruption has started.

There is a change in the earthquake activity as the magma goes up the surface. This happens because the layer of crust that the magma goes through does not all have the same density up the surface level. Softer rocks result in fewer earthquakes and harder rock results in higher earthquake activity. It is mostly not possible to know what type of rock the magma is going through. But this shows in the earthquake activity.

I’ll post more updates once I have any new information.

Danger level declared for Reykjanes volcano and Grindavík town

This is a super short update. Since there’s too much happening at the writing of this article for me to write anything useful about current situation.

  • There’s a super dense earthquake swarm happening north-west of Grindavík town. There’s also an earthquake swarm north-east of Grindavík town.
  • Almannavarnir have declared danger level for Reykjanes volcano and Grindavík town.
  • There’s a lot of earthquakes with strong magnitudes. Useful list is not possible at the writing of this article.
Dense earthquake swarm on WinSDR plot. Earthquakes happening every 10 second.
Dense earthquake activity at distance of 187 km.

This is what I am recording at the distance of 187 km from the source at Reykjanes peninsula. This is the most dense earthquake activity I’ve ever seen.

I’ll post update when I know anything useful.
