Early this morning (27-July-2019) a new earthquake swarm started north of Siglufjörður village. This earthquake swarm is in a different location than the magnitude Mw4,3 earthquake took place on 24-July-2019. This earthquake swarm is slightly more north of that location. That means this is a different fault that is creating this earthquake swarm. It is unclear if this is connected to the magnitude Mw4,3 earthquake that happened on 24-July-2019.

The largest earthquakes at the writing of this article have the magnitude of Mw3,2. There is a lot suggesting that this earthquake swarm is ongoing as of writing of this article. Last earthquake to happen was at 20:07 UTC and had a magnitude of Mw2,7 (automatic). The risk of new earthquake swarms happening without warning and being bigger than what has happened so far remains high. The location of those earthquake swarm is going to be random and might be on land or out in the ocean. There is not any way to know were the next earthquake swarm is going to happen next.
