No aftershocks where recorded after this earthquake and nothing suggests that a Hekla volcano is about to erupt at present time. But that can change without warning at any time.
Katla volcano: I think that something might be about to start in Katla volcano. But that is just a speculation that I am doing now. I am far from sure about it. But it should be clear in few hours if something is happening in Katla volcano or not. I base my assessment on rather odd changes in the tremor plot. They are hard to spot, but still there and appears to be growing it seems. But I am going to check and see what happens in few hours time. This might be nothing. But only time is going to tell us that for sure.
The interferogram was created from two pre-eruption TerraSAR-X scenes: the first one recorded almost 10 months prior to the eruption and the second one just three days before the eruption.
No explanations were found in the turmoil that was the Mýrdalsjökull yesterday.
Magnus Tumi says that it is necessary to keep up with boilers.
such activity dies out before the eruption occurs, but we can never know beforehand, what óróahryna ends with Jack and which die out.
Everything indicates that the magma is gathering under Katla. It does not necessarily mean that she will erupt says geoligist . No explanations were found what coused the turmoil that was the Mýrdalsjökull yesterday.
Magnus Tumi Gudmundsson, geoligist considers unlikely that water has caused the unease. it is more likely that geothermal energy has caused it. The activity in katla is still high and a decent amount of quakes have measured there lately and will be.
"There is increased activity in Myrdalsjokull's and has been the last few weeks ," said Magnus Tumi. "There is increased geothermal activity and increased smaller tremors. This appears on our meters, and it also showed with the glasier run this summer and the growing caldera´s in Mýrdalsjökull."
Magnus Tumi says that there is a reason to watch Katla. "This is an activity that occurs in some volcanoes before they prepare for an eruption, but it is naturally unsertain that this scenario end in an eruption," said Magnus Tumi. "But it certainly looks like she is preparing for it. These signs usually indicate that magma is coming into the volcano in relatively shallow and the increased likelihood of eruption. But if we look at the examples we have it is more common for such activity to die out before the eruption occurs, but we can never know beforehand, what turmoil ends with a eruption and which die out. we just have to watch. "
Scientists of Almannavarnir (our disaster center) are meeting this afternoon to compare notes and assess the situation "There is no emergency in progress or any such thing," said Magnus Tumi. "But the increased activity that's been lately and that unrest which came yesterday promoting that they should look into this and compare notes." email@example.com
and in another post he says that there are clear signs that the heat is increasing in the southern part of the glacier.
However, visible signs of geothermal heat is increasing and that he has done in recent weeks. Magnus Tumi says this is a sign that Katla is more active than it has in recent years. So there is every reason to have a watchful eye on Katla as they always do so but be very vigilant with her these next days and months.
They mention in the report that the caldera has been growing in Katla, did you see this anywhere else then in that report, because that is the first i have heard of it and is that not a huge indicator that the volcano is preparing for a eruption.
The pathway to the main caldera of Katla is blocked and seing as the volcano is long overdue the pressure built up elsewhere causing the Eyjafjallajökull eruption to be as large as it was. And with all the quakes that followed with that eruption new pathways were formed in Katla which are only starting to be visible now as the pressure built up again under the volcano and now we might see a new caldera form in Katla which might violently burst out from another area of the glacier.
the Katla caldera could be much bigger than we actually think it is.
