UK government failed preparing for a volcano ash threat from Iceland

According to a news article in The Independent today. It appears that UK government was unprepared for a volcano eruption in Iceland that could send ash cloud in the direction of UK. Like that did happen in Eyjafjallajökull volcano eruption in the year 2010. But according to the same news the UK government dedicated to drop such plans from there risk assessments and planning in the year 2009. A whole year before the eruption in Eyjafjallajökull volcano took place.

This was most likely also the case in other countries in Europe where the ash cloud did come as a surprise to governments across Europe and they did appear to be unprepared for it when it halted all flights in Europe for almost a week.

Geologist worry about earthquake activity in Kistufell field (Bárðarbunga volcano)

In my last blog post I did tell the news about the possibility about a eruption in the Kistufell volcano field. But that field is a part of Bárðarbunga volcano system and has a lot of earthquake activity since the beginning of earthquake recording in Iceland.

In the tonight news on Rúv about this area, Páll Einarsson geologist at University of Iceland says in the news on Rúv that there is a good reason to worry about this area. As it is one of the most active one in Iceland, but it is directly above the mantle plume under Iceland. Páll Einarsson also says in the news on Rúv that before the eruption in the year 1996, that took place in a volcanic ridge now named Gjálp there was a increase in earthquake activity in Kistufell field.

But due to continues earthquake activity there is it hard to know what is exactly going on there. Páll Einarsson also says in the news on Rúv that it is a problem that this area of Iceland lacks the proper coverage with seismometers. But they are few in this area and that makes it harder to detect the depth and the location of the earthquake that take place in this area of Iceland.

After the Eyjafjallajökull volcano eruption in the year 2010. It seems that geologist in Iceland take earthquake swarms more seriusly then they did before. As they did learn from Eyjafjallajökull volcano eruption that not all volcano start with few earthquakes just before they erupt, as is common with few volcanoes in Iceland.

Fake Hekla eruption, earthquake swarm in Krísuvík volcano

I did miss this yesterday. But apparently there where false rumours on Facebook yesterday that Hekla volcano had start erupting. While the facts where those that no eruption was taking place in Hekla people did believe this anyway and didn’t check for the facts. The reason why this did happen was that somebody did use a old news about last Hekla eruption that took place in the year 2000. But news of that eruption can still be found on the internet today.

The most serious aspect of this false rumours about Hekla volcano is that this got into the news rooms at few media station, where people asked the news reporters on why they where not covering the eruption (that didn’t exist) in the news and with breaking news on the tv. But this also got into Icelandic Met Office, but people where calling them also. According to news on this false rumours this annoyed the geologist on duty. But this takes valuable time from them for no reason.

About six thousand people fell for this prank or false rumour on Facebook.

A small earthquake swarm is taking place in Krísuvík volcano. This earthquake swarm is not big so far. The largest earthquakes have gone up to ML2.2 in size. The depth in this earthquake swarm is about 7 to 11 km. So far something less then 30 earthquakes have happened. Other then this small earthquake swarm in Krísuvík volcano, and few other small earthquake swarms taking place in Iceland or around it there isn’t a lot happening in earthquakes and volcano activity at the moment.

British Geological Survey costs the set-up of six seismometers around Eyjafjallajökull and Katla

According to Rúv it appears that British Geological Survey did pay for the set-up of six seismometers around Eyjafjallajökull and Katla volcanoes. This seismometers are able to detect lower frequencies better then current seismometers around Eyjafjallajökull and Katla. This type of sensors are normally called broadband seismometers and have frequency range down to 0.001Hz and up to 60Hz. I do not know how far the sensors that BSG did cost. But I am going to assume that they go down a bit farther then IMO sensors in the area. According to Rúv the sensors are already up and where on-line earlier this year.

They are located at following location.
Mælifellssandi not far from Slysaöldu, Rjúpnafell east of Mýrdalsjökul, two are located both sides of Eyjafjallajökull on Ásólfsskálaheiði at south and Smjörgili at north not far from Gígjökli glacier. Fifth sensor is going to be set-up in Pétursey in Mýrdal. The location of the six sensors has not been decided yet.

The cost of this project is about 100.000 pound according to Rúv.

The reason for this is that authorities in UK (and Europe) want to get more warning if there is a big eruption in Katla volcano. Mostly to prevent the air chaos that took place when Eyjafjallajökull erupted earlier this year.

Five sensors where in the area before. The sensor net is going to be really sensitive when the new sensors go on-line at IMO headquarters in Reykjavík. But more sensors give more accurate location of earthquakes, both in depth and location.
