Is something happening at Katla Volcano?

There was a 3+ quake a couple of days ago at Katla and we are regulary seeing "small swarms" there too for some time now. But I can't realy detect any big change on the tremor graphs. I think we would immediately see if magma was on the move on the red "line" on those graphs around Myrdalsjokull.

One other I still keep an eye on is Torfa. Quakes here and there and sometimes non-usual readings on the Vatnsfell (vat) graph.

Good work again Puterman with keeping us all informed.

Thanks. Torfajokull is said to be active before aseismic Hekla goes so any major activity there may mean it is time to duck!!

I think also that many do not realise this is all tied in with the Eldgja Fissure, Laki and Grimsvotn/Bardabunga.



All one big jolly complex sat on top of a massive plume possibly?

we have a bit of activity going on here

Morning BG. Ouch, not liking the look of that too much.

Looks as if there may an uptick in the tremors there as well.



Well all I can say is if it blows it will soon stop if Iceland is getting the rain we have had the past 24 hours! I think this is the tail end of Irene - enough water to flood Texas.

Mm, just been to look at the map. Looking possibly worse than the one you put up. Activity towards Hekla as well.

Yep,
not getting better and wondering if the solar flare is realy the cause now.

This has nothing to do with Katla BUT

Look at this, Grimsfjall
hraun.vedur.is...

is that a lot of harmonics? cause I have been watching the stations near Katla and they have a lot of spikes too

Well, looks like something really IS happening at Katla.

Continued and increased activity this past week.

Lets hope she only has a minor eruption when she blows. Historically we're about due and the consequences could be far worse than Eyjafjallajokull's 2010 eruption.

blog.chron.com...

Historically Katla’s eruptions have been perhaps 10 times as strong as Eyjafjallajökull, sending much larger ash plumes much higher into the atmosphere. A Katla eruption would have more serious consequences for Europe and transatlantic air travel, and probably would measurably cool the planet for a short period of time.

Think i might take up skiing!

I really enjoy watching and reading the 'fragile earth' posts, especially volcano/quake threads - I think that you do a fantastic job at getting the information out there and calming people when needed

I've been watching this thread for updates and wondered what your thoughts are now that a few days have passed?

Watching the helicorders it looks like something changed although I have no real idea what I'm looking at - perhaps it's wind?

That one has moved on, but yes the helicorder was showing wind in great abundance. Katia passed bweteen us and Iceland on Monday.

Whilst right now on the 14th she looks quiet enough, there were a couple that popped up by Hekla last night - since off the map.

Time will tell. Maybe it was just a dyke intrusion and it has settled down. I don't think I would write her off just yet however.

Some more information has come to light that Katla may have erupted this summer.

Source: Ice News

Einar Kjartansson, a geophysicist with the Icelandic Met Office, believes that a small volcanic eruption at Katla was the reason for this summer’s glacial flood in the Mulakvisl river.

But......

If a small Katla eruption did take place this summer, it does not necessarily mean that the pressure inside the volcano dropped significantly, or that another eruption is less likely than it otherwise would have been, the scientist warns.

Major increase in activity at Katla in the last few hours. I have to say I have never seen the map like this before.

This was just before 1 am last night UTC



And this is about 1 hour ago. 0735 UTC

Looks like we may have tremor at SNB, GOD and HVO
