Minor magma dike intrusion into Upptyppingar tuff mountain

Yesterday (12.01.2012) there was an minor earthquake swarm in Upptyppingar tuff mountain. But they are inside Kverkfjöll volcano fissure swarm that extends several km away from the main volcano. The largest earthquake in this earthquake swarm was around ML2.0 in size, with the depth of 14.4 km. But this was also the deepest earthquake in this earthquake swarm. But most of the earthquakes had the depth of 14.4 km and up to 7.8 km. So I am sure that this was magma, rather then tectonic movements that did create this small earthquake swarm.

This might mean that there is more activity on the way in Upptyppingar tuff mountain. As this suggests that new magma has started to flow into the magma sill that has formed under the Upptyppingar tuff mountains. It is hard to know or if there is going to be an eruption there. But I find it most likely going to be the case. But it might well be good 10 to 20 years into the future until an eruption happens in that spot. But activity started in this area in the year 2007, so there already have been good 5 years since activity started in Upptyppingar tuff mountain. For the moment however, it is all wait and see and earthquakes.

Special donation help wanted!

I want to do something for my mom and dad. How are not the most technical people in the world. The fact is that where they live there is no mobile signal inside the house, but it is good out side the house. This can be fixed with an GSM repeater. But that costs money. Around 47.000 ISK, 2.189 DKK, 244 GBP, 294€, $372. I am going to get permission from the mobile companies and the authorities in Iceland to setup this minor repeater in the licensed spectrum (900Mhz). I want to do this. But I currently do not have the money to do this at present time. That is why I am asking for donation so I can do this. But I want to buy them the smallest GSM repeater that is possible to buy in Iceland, just so that they can get GSM signal inside the house.

Thanks for the support. 🙂

Minor earthquakes in Hekla volcano system

During the past 24 to 48 hours there has been some unusual and interesting earthquake activity in south part of Hekla volcano system. I am unsure on what this means, as normally Hekla volcano does not have any earthquakes before an eruption. However, that is not the only type Hekla volcano can and has erupted over the centuries. One of the aspect of Hekla volcano eruptions is that it can and has erupted in fissure eruptions outside the main mountain. This type of eruptions can last from few week and up to almost a year. Based on the limited historical records of such events. This type of events are always basaltic lava events that do not make a lot of volcano ash when they start.

There are clues that Hekla volcano might be about to have an fissure eruption some time in the future. But when and where is impossible to know for sure at current time. How that is going to manifest it self when the time comes is also impossible to know for sure. At current time there is however no eruption starting in Hekla volcano. When it might start is an good guess, with no answer to it.
