9 Jul 11 - Last night there was a glacial flood in the southern part of the
Myrdalsjokull glacier, although reports now say that the flood has subsided.
There have been 30+ earthquakes in the area and two large cracks were discovered
over the caldera by a scientist team flying over the volcano yesterday. There
has also been strong harmonic tremors recorded. The Icelandic Met Office haven't
yet confirmed an eruption has started, but this is certainly the strongest sign
the volcano has given us that she's ready to blow.
I can't imagine the effects this will have on Europe's winter if she blows
within the next few weeks, as it will be the third Icelandic eruption (Grimsvotn,
Eyjafjallajokull, and now Katla!) in just over 12 months.
The flood is thought be the result of a small eruption underneath the icecap of
Mýrdalsjökull, probably in the Katla crater, says the Icelandic National
Broadcasting Service (RUV) website.
