Increasing hydrothermal activity and ground heat in Bárðarbunga volcano

It was reported in the news in Iceland few days ago that ground heat and hydrothermal activity in Bárðarbunga volcano is increasing and has been doing so for at least few months. Steam has been observed according to the news coming from one of the cauldron that is now in the rim of Bárðarbunga volcano caldera rim. It has also been observed that few areas that have been active for a long time are now expanding in size.

Current risk is large glacier floods from Bárðarbunga volcano as the heat is melting large amounts of glacier in this area and possible damage and danger from those glacier floods. This increase in ground heat suggests that magma is slowly pushing its way up in the caldera rim of Bárðarbunga volcano. It is not possible to know if this is the case in the caldera since that is full of glacier that is ~600 meters thick at the most deepest end. If it wasn’t for Vatnajökull glacier and the pressure it puts in Bárðarbunga volcano there would already be an eruption going on there today. It is only when the magma gets above the pressure of the glacier an eruption can happen and in the eruption of 2014 and 2015 that didn’t happen as the magma found a easier way out by forming a dyke that travelled ~46 km away from the main volcano before an eruption started. This option for the magma might be closed now since dyke like the that formed in 2014 and 2015 eruption normally only erupt once after the magma flow stops.

Hard drive problems

I am currently dealing with failing hard drives in my main computer and that makes it really slow. This might slow down my response until Friday when I finally get replacement hard drives. I also had hard drive problems with my main earthquake computer but that issue has been resolved with new hard drives.
