Large landslide in east Iceland (Ímatindi, Vaðlavík)

According to Rúv News an landslide fell in East Iceland last week (best guess). This appears to be an large landslide. It did closed down an road close to two abandoned farms in the nearby area. This landslide appears to have taken place due to heavy snow and spring melt in this area. I don’t know if there is any risk of more such landslides going to take place at this area, there is an risk of new landslides in this same area for now, at least that is my best educated guess.

Pictures of this landslide can be found here on Rúv News. All the text in that news is in Icelandic.

Steam explosion in Kverkfjöll volcano on 16-August-2013

During the night of 16-August-2013 several steam explosions took place in Kverkfjöll volcano. This steam explosions were a result of glacier flood that took place few hours earlier, since under the glacier lake in question are hydrothermal areas (hot spring). This hot springs are so hot they do not emit hot water, they emit steam and that means they are warmer than 150 Centigrade. When under pressure this water has higher boiling point. When a glacier flood happens there is a change in pressure, the boiling point of the hot water moves down, this super heats the water and a pressure explosion takes place.

I do not know if there has been any change in hydrothermal activity in Kverkfjöll volcano over the past few years. This volcano is remote and it is not easy to go there, even during the summer time. It has been advised for tourist to be careful around Kverkfjöll volcano due to this changes that are taking place there now. Hot springs and other hydrothermal features are always dangerous to get close to.

New mountain found deep west of coast of Iceland

Marine Research Institute (of Iceland) has found new mountain off the coast of Iceland. The mountain is in a plateau in the same area. But it rises up from the ocean floor about 450 meters. The area that was mapped had the size of 300 square kilometer. Depth of the ocean at this location is around 1400 meters. This mountain is possibly an old tuff mountain (volcano). But that is not confirmed. According the news, this mountain has youthful look to it and around three craters where spotted on it. The age in this area is around 20 million years. So this might be a extinct volcano from the time period when volcano activity was ongoing in this area. But it most likely has never been above the coast line.

They found more then just this mountain in this survey. They also found more mud volcanoes off the coast of Iceland. Some of them are reaching 350 meters off the ocean floor.

Mud volcanoes appears as spikes in this image. This image has has things four times larger then they actually are. Copyright of this image belongs to Marine Research Institute.

There are many more unknowns off the coast of Iceland. As the ocean floor is largely unexplored today. As are many other parts of the ocean floor around the world.
