It has been few days since the eruption in Holuhraun has ended and everything is quiet for the moment in Bárðarbunga volcano. What is going to happen next is a big question and nobody has the exact answer. Here are few options.
- Nothing is going to happen. The rift is going to continue without more eruptions.
- New magma intrusion is going to start soon in Bárðarbunga volcano. New eruption is going to start days to weeks later.
There is also high risk in my view of eruptions in Hamarinn volcano (also called Loki-Fögrufjöll). That volcano system is inside Bárðarbunga volcano and dyke intrusion from Bárðarbunga to the south might start a volcano eruption in it. I don’t know how big such eruption would be, it is my estimate. Dyke to Torfajökull volcano is unlikely to happen. I however cannot rule it out at this point.
What is going happen in Bárðarbunga volcano depends on many factors and not all of them are known. What is known is that heat has been increasing in shallower parts of the crust and caldera for the past six months and those signs are not good. What is not known is the time in question. Next eruption could happen tomorrow or nothing can happen for years. There is no way to know when next eruption is going to happen.
Currently I am just monitoring Bárðarbunga volcano and waiting to see what happens next. The text above is just speculation, not fact. It is not clear what is going to happen next. The only way to know that for sure is to wait until next eruption starts and that might be a long wait.
