The man made earthquake swarm in Hengill volcano that happened today seems to have subsided, as it is most likely that Orkuveita Reykjavíkur has stopped pumping down water into the new drill hole that they where using today.
Over 400 earthquakes have been recorded in this man made swarm. I am not sure on the depth on most of the earthquakes. But it is in the range of 1 to 10 km from what I can tell. The largest earthquake in this earthquake swarm was ML3.4 in size, it had the depth of 3.9 km.

I am going to post earthquake traces on Sunday or Monday. I am currently not at “home” (where my main computers are located), as I am taking this weekend off (if nothing large happens this weekend).

It is hard to know what happens as Orkuveita Reykjavíkur continues to pump down water into Hengill volcano. All that can be done is too wait and see what happens.

Off-topic. Northern light could be very good tonight. But the weather is not very favorable in Iceland or Scandinavia.
Aurora could be visible right now in north Denmark, south Norway and north Scotland, according to spaceweather.com
Ahh, well you got there before me Irpsit but this site: http://www.gi.alaska.edu/AuroraForecast/3
has the whole of the British Isles under the green banner for the next hour. Nothing where i live in the south west UK, just looked!
I also got an alert from Lancaster University but so far nothing here in Lancashire. I am watching here in Iceland also.

Great northern light this last hour. Lots of strong green and purples. Now it has fainted again but the whole southern half of the sky is still full of a greenish glow.
You will not see anything is the Peace Tower webcam because the aurora is moving southwards, and that camera points north.
Jon, I’d like to donate some for your new geophones as I am happily using them and I think it’s a privilege to have this data online. The only thing is that I’ve had some bad experience with PayPal, is an international bank transfer also possible?
Yes, that can be done. Just send me a email and I will forward you my Danish bank account information too you. 🙂
No Aurora here in the Midlands, UK… there never is. *sulks*
Great news on the Geophones, Jon! I’ll do what I can! 🙂
Oh, if you were in Scotland and watching it 30min ago, you would for sure see it over the northern horizon. But don’t expect it to see it from south of Edinburgh. And it is best to see it with a dark sky.
The aurora is visible now hanging over the southern horizon here in south Iceland but it is now much less bright. Yet the aurora has moved really south!
I’m a bit jealous, but one day I shall pluck up the courage to cope with a plane or boat to travel north to see it! 🙂
Its hardly to see in Reykjavik – I guess we are actually at the northern edge of the aurora oval.
Now it’s calm, but 1 hour ago the aurora was pretty strong and beautiful, and it lasted about an hour, between 9 and 10pm. I am waiting to see it again before the clouds come. The sky has a faint green color over the southern part.
Eh?
You are far down south of me… And I see it pretty well.
Doesn’t matter. Will not be the last show this winter.
New blog post is up! 🙂
