Update on 5-August-2022 on the eruption in Meradalir valley

This is a short update because not much has changed in the last 24 hours in the eruption in Meradalir valley in Fagradalsfjall mountain.

  • The eruption is now in 120 meter long eruption fissure. Currently the output of the eruption is around 18 m3/sec according to yesterday’s measurements.
  • The new lava has now flowed over the lava from last year (2021) and into eastern Meradalir. This is about 1 km distance that river of lava has flowed.  Image of that can be found here on Facebook.
  • According to chemical analyse of the magma. This is the same magma that was erupting when the eruption in the older crater stopped erupting in September. This shows that this magma is older and the new magma has not yet reached the surface.
  • Fissures on the ground north-east of the eruption site have started to move and getting wider according to experts that are in the area. This strongly suggests that an eruption is about to happen soon in that location. When it starts is impossible to know. But this is going to close one way to the eruption and if eruption starts in new location south of the crater, seeing and viewing this eruption might start to get difficult or impossible, at least the part in Meradalir were the current eruption is happening now.

I think that is all for this Friday. Next update is going to be on Friday 12-August unless something major happens in this eruption and that might just happen.
