Bárðarbunga volcano daily update for 21-October-2014

This is the daily update for Bárðarbunga volcano.

Largest earthquake today had the magnitude of 5,3. Second largest earthquake had the magnitude of 4,7. The magnitude 5,3 earthquake had the depth of 15,6 km. This suggest that something is happening at depth inside the volcano. What that exactly is bit unclear that the moment. Other earthquakes today have been smaller, but there have been good amount of magnitude 3,0 and 4,0 earthquakes taking place today.

Earthquake activity has been increasing along the dyke today. This suggest that pressure is increasing along the dyke, this might mean that more magma is flowing into it at the moment. After what appears to have been some type of pressure drop earlier today. What this means is unclear, but an eruption under the glacier continues to a be a big risk in Bárðarbunga volcano. The Holuhraun lava is now around 60,4 square kilometres in size. This is according to latest measurements that have been taken. The volume of lava is considerable more, since the lava is up to 10 – 30 meters thick at locations and might be getting thicker as the time passes. I don’t think there is anything more to report currently.

Bárðarbunga volcano Monday update on 20-October-2014

I am sorry for this late update. I was working on my server computer. More details at the end of this article.

Overview of weekend (18 – 19-October-2014) activity in Bárðarbunga volcano

Strongest earthquake in Bárðarbunga volcano during the weekend had the magnitude of 5,4, second largest earthquake that took place during the weekend had the magnitude of 5,2. Other earthquakes have been smaller. Eruption in Holuhraun continued as it has been doing so for the past 1,9 month. During the weekend the new lava field in Holuhraun became the biggest in Iceland for the past 200 years. Other then this, nothing major did happen far as I know.

Monday 20-October-2014 activity update

Earthquake activity has been in high today, compared to yesterday (19-October-2014). Strongest earthquake had the magnitude of 5,0 and the second largest earthquake had the magnitude of 4,8. Other earthquakes where smaller, but a lot of magnitude 3,0 and 4,0 have happened today. Earthquake activity along the dyke has been increasing again after few quiet days.

The lava field in Holuhraun continues to grow and is now around 61 square kilometres in size. That is an (my own estimate) around 0,9 km² of lava in the Holuhraun area. Making this the largest eruption in Iceland for the past 200 years and it just keeps going on. The 16-October-2014 marked two month anniversary of start of the activity in Bárðarbunga volcano, it is going to be two months since the eruption started on 29-August-2014. The first eruption in Bárðarbunga volcano happened on 23-August-2014 and happened under the glacier, that eruption ended the same day. Other then what I report here, I don’t think there is nothing else to report about the eruption in Bárðarbunga volcano.

Notes about Bárðarbunga volcano

Please note that there is no evidence of felsic or intermediate magma in Bárðarbunga volcano. It is all just Ultramafic magma that is now erupting. For more details on magma please click here (Wikipedia). The glacier inside the caldera is moving down with the caldera. There is no evidence of any eruption taking place inside the caldera so far. It might happen in the future (and the wait might not be long), so far it just has not happened yet. There is a chance of hydrothermal activity taking place in Bárðarbunga volcano due the magma warning up the crust, that is however only of the magma is shallow as 1 – 2 km deep in the crust.

FreeBSD server

The reason why I didn’t update last weekend and late today is that I was trying to move my server from FreeBSD to Gentoo Linux. That did not work. What my server does is few things. Among the thing that my server does is to count earthquakes in Iceland like this image shows.

It also runs my Minecraft server. I Play that game since I don’t play many games now. Both due to lack of time and interest. I play the game with my friends at times, when we have time to do so.

Lava in Minecraft. It doesn’t create lava fields. I guess that would be bad if it did that. Copyright of artwork belongs to Mojang and / or Microsoft. I took the image from the game using it screenshot function.

It is important for me to keep the earthquake counter running when I can do so. I also have to have my Minecraft server up and running so I can play when I have time to do so.
