Increased ground heat measured in Surtsey island

It was in the news yesterday (21-July-2015) that scientists have measured higher ground heat in Surtsey Island. The change is 10 degrees (Celsius) from measurements taken some two to three years ago. The theory is that the ground in Surtsey island started to warm up after an earthquake that happened last spring (2015). There have been few earthquakes in Vestmanneyjar volcano system during the past few years, no major swarms have taken place so far.

It is clear by the increased ground heat that magma is on the move in Vestmanneyjar volcano system. It’s too early to know if an eruption is going to take place in next few years. At the moment there is nothing imminent suggesting that is the case, volcanoes often warm up at the surface just too cool down. The largest risk now in Surtsey island are possible steam explosions. They are only risk to local bird and plant life in the summer time.

Donations: Please remember to donate to support my work. I do have a summer job at the moment, yet I continue to broke (#$%&%$#) and having problems (#$$%&). Thanks for the support. 🙂

Long term plan: I’m currently building a new long term plan. I am going to write about it on a new site that I am going to set-up once I stop working. That is going to be by the start of November (I hope).
