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.<\/p>\n<p>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 Hofsj\u00f6kull 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 Hofsj\u00f6kull volcano outside of the caldera area.
