Two swarms in the past nine days near Hellisheiði. Todays activity is definitely shallower overall than nine days ago (See red underlined tremors in upper graphic.) First reported in this post.
Not sure what this means, but as there are webcams close by, if any activity does make it to the surface, we're in a very good position to see it happen on the Eastward facing camera of Highway 1 (See previous post on Hellisheiði.) As it is close to Icelands biggest geothermal power generating facility, I'm assuming that the guys at Hengill will be keeping a close eye on their seismographs too. Will check again first thing in the morning before I go to work.
Update: Tremor activity has slid back a little and the swarm seems at the time of writing to have diminished with most activity back down at the 2-5km level.
