Earthquake swarm at Katla volcano under Mýrdalsjökull glacier

The icecap of the Mýrdalsjökull glacier covers an active volcano called Katla. The caldera of the volcano has a diameter of 10 km (6.2 mi) and the volcano erupts usually every 40–80 years. As the last eruption took place in 1918, scientists are monitoring the volcano very carefully as they believe an eruption of Katla is on the cards, particularly after the eruption of Eyjafjallajökull began in April 2010. Since 930, 16 eruptions have been documented.Wikipedia
Update: July 9, 2011- According to the Icelandic news, a glacier flood started around midnight in Múlakvísl Glacier River that runs from Mýrdalsjökull glacier. Last time this type of event did happen was in the year 1955, when a minor eruption is believed to have taken place under the Mýrdalsjökull glacier. I do not know if that is the case now; as this might just be hydrothermal water being released due to increased activity in hydrothermal areas that are in Mýrdalsjökull glacier. Following the flood, there is a strong smell of sulphur and there might be dangerous gases in it. At current time, the flood appears to be growing and according to the news (written at 01:54 UTC) the bridge was still safe. But there was just 1 meter from the river and up to the floor of the bridge.Jonfr.

    We would have to see alot more signs to say with any confidence that it is erupting. Signs such as a very large # of quakes (dozens and dozens) with some large quakes well over 3.0, consistent harmonic tremors, then some flooding starting to appear on the sides of the glacier. Then kafloooey. A small swarm like this does indicate an eruption is starting.

    Well, it does NOT yet state that… After we see daily swarms with tens of quakes we can start talking about an eruption coming in the near (days to weeks) future.

    Yeah that is quite the rumble. In regards to Hekla I find it quite interesting that the strain at Hella and Burfell has started to go continually in complete opposite directions:

    Didn’t somebody on this blog have the notion that this would happen if something was pushing its way up between the two measuring stations.

    This is a strange story, Series of pyrotechnical explosions rocks Turkmenistan
    ­There are reports of massive explosions in the city of Abadan in Turkmenistan, which according to a Turkmen government statement were caused by fireworks set off by unusually hot weather. The government statement said there were no victims, but despite a media and internet blackout, unconfirmed reports say there have been casualties. Military and emergency vehicles have reportedly left the capital Ashgabat, 20 kilometers away, in large numbers. Abadan, a city of 50,000, is said to be in panic. The Cabinet and Security Council met in an emergency session chaired by the president to coordinate the response. A large scale evacuation is underway as explosions were reportedly still taking place 12 hours after the initial incident, with rounds of unexploded material scattered widely. There are reports – again unconfirmed – that an armory depot caught fire, triggering major explosions. The authorities have set up an emergency center providing water and medical assistance
