Today (20.03.2013) at 10:51 UTC an earthquake swarm started on the Reykjanes ridge. This earthquake swarm was about 850 km away from Reykjavík so it was not felt. This also gives little information on what is happening in this location. Since the depth of the ocean at this location is around 2 to 3 km. The largest earthquake in this swarm had the magnitude of 4.8 according to automatic EMSC results. The range of magnitude that was detected is from 4.6 to 4.8. The estimated depth is around 10 km. But that might not be correct.

More information on the strongest earthquake in this swarm can be found here, on the EMSC web site. I do not know if activity is going to continue in this place. This location is just too remote to know that for sure.
This is a sticky blog post. Please look at the newest one below this one.
I have put up rather heavy spam protection when users are registering. The reason is simple. This blog is getting flooded by spam registration and I cannot have that. Just in the past 24 hours that spam system has stopped 678 spam bots from registering (multiple tries). I am not saying this is going to stop all of the spam bots (I delete spam bots when I see comments from them). But it is going to stop many of them.
If you are going to register please follow the on screen guide. Do not register multiple times if your first attempt fails. Contact me or just wait 10 days and then try again. It might take some time for the email to arrive in some cases. This is not always the case and you should get your registration email right away.
If you are having problems with this new system please let me know so I can attempt to solve it for you.
During the night there was an earthquake deep on the Reykjanes ridge. This earthquake had the magnitude of 4.8 according to automatic result from EMSC.

Due to earthquakes location there is not a lot of details on it. But this location on the Reykjanes ridge has been seeing some activity in the past few months. This might well just be normal tectonic activity for this area. More information on this earthquake can be found here.
