Short earthquake swarm in Katla volcano

On 17-December-2016 a small earthquake swarm took place in Katla volcano. Only few earthquakes took place and the largest had the magnitude of 3,3 and the second largest earthquake had the magnitude of 2,1. Other earthquakes where smaller in magnitude.

This earthquake swarm only lasted for ~30 minutes. It was also slightly south-west of 15-December earthquake swarm, this is the most activity I have seen in Katla volcano in December since I started watching the volcano in 2001 (around that year). All that can be done for the moment is to continue to watch the activity in Katla volcano. Since it’s not possible to know when a eruption is going to take place.


Please remember to support my work with donations. As I explained in the article on the 16-December I bought a new laptop so that I can work while I’m travelling. I was unable to get a loan for it in Iceland (and Denmark) so I bought it outright without having a good plan on how to pay it fully (working on that problem with a help from my bank). Thanks for the support. 🙂

    1. I had to remove the program since it was wasting too much of my battery, but if you have a extra phone that is no longer in use it would be good for that.

  1. There has been a little spike in conductivity at Múlakvísl which rose to 309.5 in the middle of the night. Could this indicate that another geothermal vent(s) has become active?(I realise this is nowhere the level which causes great concern of around 600.)

    1. A small collection of water might also have melted trough its barrier and flooded out. There is also a risk of an old volcano ash getting into the river and make the conductivity higher that way, since the weather has been different this year than last year (for example). Lack of snow and warm weather continues to melt the glacier.
