Argentina's Seismic Administration reported a 7.3 earthquake near one of their Antarctic bases.
There were no injuries or damage, but this made me realize, I had never thought about earthquakes in Antarctica, but they obviously happen, since there are volcanoes there too.
What would happen if a very powerful earthquake, say magnitude 9, occurred underneath one of the very deep ice shelves? Would they be broken apart into pieces? Would it be thick enough to not break up, in which case, would then entire ice pack "rise" and come ashore?
Has such an event ever been documented, or even studied in computer simulations? I find it intriguing and a bit scary!
