During the past several hours the amount of water in the glacier flood from Grímsfjall volcano has not dropped a lot, but this glacier flood started two days ago (27.01.2012 around 12:00 UTC). But that might be down to heavy rain in the area. Normally a glacier flood from Grímsvatn lake (inside the Grímsfjall volcano caldera) last for about one to two days during a normal glacier flood. It is believed that this glacier flood is from Grímsfjall volcano glacier lake. But it might be hard to confirm this during this time of the year.
Possible noise from the glacier flood on this SIL station. This might however be increased noise due to heavy rain on it. Copyright of this picture belongs to IMO.
I have known for some time now that Grímsfjall volcano is preparing for a new eruption. This I know because of the increase in earthquake activity and increased hydro thermal activity in Grímsfjall volcano. So far there is nothing that suggest that Grímsfjall volcano is going to erupt this time around, at least for the moment. I am expecting this glacier flood to be over in the next several hours. No earthquakes have happened in Grímsfjall volcano during this glacier flood. I do not expect them to take place unless magma starts moving inside Grímsfjall volcano. Be that dike intrusion or start of an eruption.

Hi Jon, I thunk there may hav been a mag 5.2 quake on the mid Atlantic ridge about an hour ago, sorry I don’t know more.
– Regards.
Close to the Equator, no effect on Iceland.
There’s a nice swarm going on at Aegean Sea, some 40-50 km SW from Santorini. The depths are relatively shallow, so no I suspect no direct connection to Thera volcano. However, the strongest quake so far has been M4+ which could have been felt at Santorini, too.
New EQ svarm starting in Katla?
I think so…
Looks pretty much like it.
The earthquakes can be seen here, on Heklubyggð geophone.

Skeiðflöt geophone goes up this week. So more earthquakes should be seen once it is up and running.
New blog post is up about the earthquake swarm in Katla volcano.

There has been a significant up-tick in activity at Santorini in the last few days
Well, the most recent swarm is located some 40-50 km SW of Santorini, and thus it is not directly related to Thera. Check the facts first, so you’ll be able to rule out the most obvious misinterpretations.
Big quakes happening in Katla now.
