Two things have happened. 1) new sensors have been installed, which are more sensitive. 2) frost earthquakes have been happening i.e. frost cracks the rocks which is picked up by the sensors. However having said this there is magma moving

Well we wait for the big one, however there is loads of activity around Krýsuvík volcano in Iceland

Bearing in mind the moon's very close approach [it is just rising in the East at the moment], this does seem to be coinciding with a bit more activity at Katla. At closest approach, the moon is about 12% nearer than the furthest position. As a square law relationship, this does seem to imply a bit more gravitational tension. I assume that only a long term statistical analysis would actually suggest whether there is a correlation between lunar position and earthquakes, eruptions etc. en.vedur.is/earthquakes-and-volcanism/earthquakes/myrdalsjokull/

Firstly a good Blog site about Icelandic volcanoes www.jonfr.com/volcano/Next the Icelandic METO site en.vedur.is/earthquakes-and-volcanism/earthquakes/You'll notice that there has been a sudden uptick in activity (more than I've seen before NOW THE IMPORTANT BIT !!! This is a quote from a post to the first website (this was posted before the recent uptick) "There is a rumor floating around in scientific circles, that a BGS insider at a private party in Peterborough last weekend had one to many drinks and let a cat out of the bag. Apparently, there is a hot debate ensuing over whether-or-not to publicly sound the Katla Alarm. At issue, newly installed sensors recorded massive week over week expansion rates of buldge accelleration on the northeast rim during all of February. Evidence is mounting that Katla is filling her cauldron and the charts are eerily similar to Mt. Saint Hellen’s in the months before her 1980 errupted. At the core of the rumor, resides the allegation that top BGS officials believe Katla has a better than 80% chance of a catastrophic eruption during 2011 that may shutdown large sections of eastern Europe for months." We have not had a large eruption of any Icelandic volcano since international flights started, if this one goes of there is a large glacier sitting on it so there is likely to be very nasty volcanic ash that will damage plains that fly through the cloud (as water will come into contact with the eruption). This will make the 2010 eruption of Eyjafjallajökull look like a burp! Also i just went to the Icelandic Meto site page "tremors measurements near Eyjafjallajökull" hraun.vedur.is/ja/Katla2009/gosplott.htmlNormally it has graphs of tremors and says at the top "Katla is not erupting !!!" Now it says "Page not found" "It is possible that you haven't got access rights to the page or that you made a typing error." This page is accessed from a link on the main website so I didn't type it in wrong, so maybe the link is broken or maybe it's not Anyway time will tell ;D

byz, thanks for the info! It will be interesting to see what Katla does over the ensuing months.
I see no reason why they should wonder whether or not to publish data regarding the volcano's activity and movement. That is the easy call. The difficult call is on the politicians and civil officials to decide what to do based on the data.
Data is just data. It should be released simply for what it is.

Indeed data is just data, however it has become fashion in the last few years to hide data. The weird thing is that that page has been there for ages and suddenly it doesn't work anymore just as Katla starts stirring. When it finally does go off I'm going out to buy lost of canned foods

From the Eruptions blog... bigthink.com/blogs/eruptions/"Well, it looks like Iceland is going to be in the news again this summer. Jon Frimann and others noted a sharp increase in seismicity under the Vatnajökull icecap at Grímsvötn today and MBL.is has confirmed that if an eruption hasn't already begun under the icecap, then one is likely to be starting soon according to geologist Louw Sveinbjörnsson. There appears to be confirmation of an ash or steam plume possibly reaching 1.8 km / ~6,000 feet above the volcano, but again, the details are scant. The plume from Grímsvötn seen on May 21, 2011 (middle of image, on horizon): Grímsvötn last erupted in 2004 with some impressive plumes produced by the eruption melting through the Vatnajökull icecap under which the volcano sits."

news.yahoo.com/s/nm/20110604/wl_nm/us_chile_volcanoChile volcano erupts, spits towering ash column Reuters Email Print – Sat Jun 4, 6:18 pm ET SANTIAGO (Reuters) – A volcano dormant for decades erupted in south-central Chile Saturday, belching ash over 6 miles into the sky and prompting the government to evacuate several thousand residents, authorities said. Winds fanned the ash toward neighboring Argentina, darkening the sky in the ski resort city of San Carlos de Bariloche, a government official there said, adding the city's airport had been closed. The eruption in the Puyehue-Cordon Caulle volcanic chain, about 575 miles south of the capital, Santiago, also prompted Chilean authorities to shut a heavily traveled border crossing into Argentina. It was not immediately clear which of the chain's four volcanoes had erupted because of ash cover and weather conditions. The chain last saw a major eruption in 1960. Local media said the smell of sulfur hung in the air and there was constant seismic activity. "The Cordon Caulle (volcanic range) has entered an eruptive process, with an explosion resulting in a 10-kilometre-high gas column," state emergency office ONEMI said. The government said it was evacuating 3,500 people from the surrounding area as a precaution. It was the latest in a series of volcanic eruptions in Chile in recent years. Chile's Chaiten volcano erupted spectacularly in 2008 for the first time in thousands of years, spewing molten rock and a vast cloud of ash that reached the stratosphere. The ash also swelled a nearby river and ravaged a nearby town of the same name. The ash cloud from Chaiten coated towns in Argentina and was visible from space. Chile's Llaima volcano, one of South America's most active, erupted in 2008 and 2009. Chile's chain of about 2,000 volcanoes is the world's second largest after Indonesia. Some 50 to 60 are on record as having erupted, and 500 are potentially active. (Reporting by Felipe Iturrieta and Antonio de la Jara; Writing by Simon Gardner; Editing by Peter Cooney)
