This is a short update. Since there is not a lot of information about this.
- The crater might collapse at any time without warning. Geologists that monitor the eruption have noticed that the crater has started to get larger and is now full of lava. This means it is going to collapse. What direction is not known. It is my view that it is going to collapse to the east because of least resistance in that direction.
- When the crater collapses the lava is going to flow more than 100m/s in whatever direction it flows.
- Tourists are in high danger close the crater because of this collapse risk.
- Dyke intrusion has been detected east of Keilir mountain. Along with increased ground temperature, that means the magma is at shallow depth in the crust. This area might erupt soon in similar way as is now happening close to Litli-Hrútur.
This is all the information I have now and only thing that has changed in the eruption in the last 13 days.
