At current time there are two main earthquake swarms taking place in Iceland. The first one is at Kr\u00edsuv\u00edk volcano and has been going on since early this week. Currently there is nothing to suggest that it going to end any time soon. This earthquake swarm however sometimes stops for several hours and up to one to two days at the longest. Most of the earthquakes taking place are less then mag 2.5 in size. It is not clear why this earthquakes are taking place. This might be tectonic process or something to do with the magma intrusion that is taking place in Kr\u00edsuv\u00edk volcano.<\/p>\n
The second earthquake swarm is taking place at Her\u00f0ubrei\u00f0art\u00f6gl with earthquake taking place at Her\u00f0ubrei\u00f0 at it’s north limits. Several mag 3.0+ earthquakes have taken place. This earthquakes appears to be due to tectonic process in the area. But I have heard theories that this process might have started due to influx of magma into the Askja volcano that is close to earthquake swarms in Her\u00f0ubrei\u00f0art\u00f6gl. At current time I cannot confirm that this ideas are correct or not. This earthquake swarm is ongoing and does not appear to be ending. But there are breaks in it that last from few hours and up to one day at the longest. Please note that Her\u00f0ubrei\u00f0arfj\u00f6ll is a central volcano that is active. It is not on the GVP volcano list<\/a> for the area. This volcano is located inside Askja fissure swarm and has many active fault lines that cross it from north-south. <\/p>\n The newest earthquake swarm that appears to be at slow start is taking place in Esjufj\u00f6ll volcano. But since activity started there in early October 2010 earthquakes appears to be on the rise in Esjufj\u00f6ll volcano. It is worth noticing that earthquake swarms in Esjufj\u00f6ll appear to start slowly but they due appear to peak after 20 to 180 hours after they starts. This earthquake activity is due to new flow of magma into Esjufj\u00f6ll volcano. <\/p>\n","protected":false},"excerpt":{"rendered":" At current time there are two main earthquake swarms taking place in Iceland.
