The first one is water that has been superheated in the crust. The second option is that magma is now moving in Torfaj\u00f6kull volcano. This type of activity has happened before without any eruption happening. I think that is going to be the same now at the writing of this article. Since this is an active volcano the situation can change quickly and without warning.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">There are no web cameras in the area that I know of.
