Update two on the Askja volcano earthquake swarm

The earthquake activity in Askja volcano continues with no clear signs that it is about to stop. Since midnight around 200 earthquakes have happened at the writing of this article. Icelandic Met Office is currently holding a meeting about this earthquake swarm in Askja volcano.

There seems to be a pulse activity in this earthquake swarm. Activity drops for several hours before increasing again and then slows down again. That is possible clue that this earthquake swarm has its origins in magma activity that has not yet reached shallow levels of the crust. There is no deep earthquake activity in this swarm and that might not happen. What exactly is going on in Askja volcano remains unclear at the writing for this article.

There are now two possibles of what might happen next

  1. Earthquake activity continues until an eruption happens. This would be a lava eruption with no or limited amount of volcano ash happening in the process.
  2. This earthquake swarm continues until it just stops and no eruption happens.

What happens is impossible to know for sure since this earthquake activity is a mystery as of the writing of this article.
