Yesterday there was an interesting swarm of small earthquakes in Hekla volcano system, or to be accurate. The earthquake swarm took place on the edge of Hekla volcano system. How far into the SISZ it was I do not know. For some unknown reasons, the earthquakes have not yet been reviewed. So errors are in there location and depth.

I have no idea what this means in terms of possible eruption in Hekla volcano. But this activity is interesting. But this is however not something that is new to this area. But it is uncommon anyway.
Activity in Hekla volcano system can be monitored on my web page with webicorders. Some of them have high human and wind noise however. As this is not expert setup that I am using.
Thanks, Jon.
@Jon: On your Katla Helicorder there appears to be an EQ at arround 11:55 but nothing on the IMO maps. What is this?
This is just a noise. It happens that they make red spots in the webicorders. You can tell by the wave form. Noise is normally just a single wave. But earthquakes are many waves.

Thats quite a swarm at Hengil, even if they are pumping more water down. the area seems quite a bit larger than usual.
I hope to write a new blog post tomorrow. 🙂
