Hydrothermal activity creates dangerous ice cave in Hofsjökull volcano

Hydrothermal activity has formed a ice cave in Hofsjökull glacier (volcano details here). According to an announcement by Icelandic Met Office this ice cave is dangerous due to sulphur (SO2) pollution and that it goes above 60ppm. That can result in loss of breathing, loss of vision and damage to eyes and lungs. People should only enter this ice cave with gas monitoring hardware on them. One seven year old girl passed out due to sulphur poising some weeks ago in a trip to this newly formed ice cave. There is also a high risk of collapse from the roof of the ice cave as ice appears to be loose above it and can collapse down without warning at any time.

There is also a risk of hydrothermal activity increasing and that is going to result in more sulphur (SO2) gas in the cave and other dangerous gases coming up. This appears to the same location that had increased activity 15 years ago that also formed an ice cave. The reason for this increase in hydrothermal activity is unclear since no earthquake activity has been recorded in Hofsjökull volcano for the past 10 years. This means earthquake activity above background levels, one or three earthquakes are recorded each year in random part of the caldera or parts of Hofsjökull volcano outside of the caldera area. Höfsjökull volcano is on its own rifting zone (information here, related paper here) (marked as SRZ on some documents) along with Kerlingarfjöll volcano (it is now under GVP as Hreppar. I don’t know why that is).

  1. I am soon going to be moving PayPal to my Icelandic PayPal. I won’t close down my Danish PayPal just yet but I am going to move everything away from it by next week.

    Since I am moving to the Icelandic PayPal I am also going to be updating the currencies that people can donate it. It is not just going to be in Euro any more.

    Currencies that I going to support are this.

    Other currencies are not supported (but donations are possible in other currencies even if I don’t support them). This is the list as it is currently. It might change in the future and I’ll post the details on the donation website soon as I update the details.

    Bank information won’t be changed until start of June. If you donate with PayPal directly (not using the PayPal button). Please update your email address, the new email address is already in the information on the donation website.

    Thanks for understanding. This change has to happen because I am permanently moving back to Iceland by the end of June-2018.
