judging from the above image , the ice is kept from sliding into the ocean because part of it is in a depression.
this should prevent a massive tidal wave that would be the result of the ice sliding into the ocean.
what worries me is that as the ice melts and the depression rebounds , the ground underneath will heat up due to depressurization.
this massive ice will then have the tendancy to crack and explode terribly with a force that we have never experienced here on earth.
that will make the St Hellens erruption look like a firecracker.
if you have ever used a big bowl to freeze water in for ice , I
use a stainless steel bowl that holds apx 1 quart of water , and when I run warm water over it to release it from the bowl so I can use the ice , it cracks in hundreds of pieces all of a sudden.
sometimes large chunks of ice fly out of the bowl.
and every time it reminds me of just how violent a glacier can be , and it makes me think of what would happen in antartica.
and this is only 1 quart of ice.
