Isn’t interesting that the various depth ranges given in various reports differ as they do.
There is somewhere between a 100 meters and a half mile of ice -—dah, its a glacier, I would tell them.
What we want to know is the ice thickness above the eruption now underway and the ice melt potential down below that as the above area superheats and causes melt off of the perimeter. Will small coastal villages be swept away — information distribution is not done too well anymore.
This is more than about flooding.
A volcano under ice is putting out heat as well as hydrogen sulfide which turns into sulfuric acid that breaks down the rock underneath. The combination of the degraded rock and water “greases the skids” and when the heat finally melts the glacier to where it breaks off, you can get a lahar (a massive landslide, mud/debris flow) that can travel 100 miles per hour down a mountainside and literally fill the valley below in less than an hour.
That can happen even if there is no eruption of the volcano.
How much could ocean levels rise from the amount of ice it could melt?
