Then a earthquake swarm started like this, slowed down for few days before it increased again and the eruption happened. It is unclear what direction the dyke might move to, but most likely is south-west in the direction of Torfaj\u00f6kull volcano and Katla volcano. If that happens, such dyke activity might get those volcanoes upset or start and eruption in them.<\/p>\n<p>I am going to post update as needed for B\u00e1r\u00f0arbunga volcano as this activity continues.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Today (14-January 2025) at 06:08 UTC an dyke intrusion started in B\u00e1r\u00f0arbunga volcano.
