Nächster Vulkan Ausbruch auf Island
31.10.2010 um 19:07@sepp0309
also auf jeden fall waren die vulkanologen auf island sehr gespannt:
es gab gleich mehrere meldungen für heute mit updates:
Wenige Stunden vor einem Gletscher Flut begann aus Grímsvötnum. Aber es war nur vor wenigen Augenblicken bestätigt. Die Flut Lärm kann auf folgende SIL-Stationen rund um Vatnajökull sehen.
Grímsfjall (erhöhte Lärm)
Kalafell (erhöhte Lärm)
Dieser Gletscher Hochwasser wird erwartet, dass es in Spitzenzeiten etwa 4 bis 5 Tagen zu erreichen. Ist dies eine Wiederholung des Jahres 2004 Veranstaltungen ein Ausbruch in Grímsfjalli in etwa 1 bis 4 Tagen beginnen ab jetzt sollte. Aber wenn das spielt sich Leuchtmittels darf nicht überschritten wie das Jahr 2004 Eruption, bleibt abzuwarten. GVP hat die Eruption Geschichte Grímsfjall hier.

Expecting a glacier flood and possibly of a eruption from Grímsfjall at any time
Posted on October 31, 2010 by Jón Frímann
According to the Icelandic news today geological scientists in Iceland are expecting a eruption and a glacier flood from Grímsvötnum at any time and without a any warning. But last week they did detect harmonic tremors on the SIL station that is on Grímsfjall volcano. It is not known if the harmonic tremors where created by water or by magma.
Currently the Grímsvötn lake is full and is ready to burst at any time without warning. Because of that scientists and Iceland Met Office have increased the monitoring of Grímsvötn and Grímsfjall volcano. It has been six years since the last eruption at Grímsfjall (2004) and it only where six years before that eruption (1998).

A ML3.4 earthquake at Grímsfjall volcano
Posted on October 31, 2010 by Jón Frímann
At 03:19 UTC there was a ML3.4 earthquake at 2,5km depth at Grímsfjall volcano according to the automatic SIL system that Icelandic Met Office has. This earthquake does not appear to be a after effect of the ML4.0 earthquake at Blöndulón few moments before that. Currently there have not been any other earthquake in Grímsfjall volcano. But that might change soon if this is a start of a eruption in Grímsfjall volcano. But it is going to take few moments to be clear on what is happening.
Currently there are no indicators that a eruption is starting in Grímsfjall volcano.
Update!
This earthquake was when reviewed size ML2.3 at the depth of 2.8 km.

Magnitude ML4.0 earthquake hits Blöndulón
Posted on October 31, 2010 by Jón Frímann
Over the past few days (since 26th of October 2010) there have been earthquakes happening at Blöndulón. This earthquakes are intraplate earthquakes and it unclear why these earthquakes are happening.
At 02:35 UTC a earthquake with the size of ML4.0 did hit Blöndulón according to automatic SIL system that Icelandic Met Office has. So far this is the strongest earthquake to hit this area since the earthquake swarm did start. This earthquake appears to be a start of new earthquake sequence in this area. But several smaller earthquakes have happened as a result of the ML4.0 earthquake. The depth of the main earthquake was 1km. I do expect that it was felt in nearby farms that are closest to Blöndulón.
I am expecting more earthquakes in this area over the next few days. It remains to be seen if they grow in size or not.
Update!
When reviewed the size of this earthquake was ML3.8 at the depth of 21.1 km.
