Ahah!
So a mountain (where most glaciers are, last tiem I looked) composed of several millions of tons of rock, is going to "move" seismically when a few tons of water/ics are removed from the mountian.....
But the moutain is moving more than every day by the moon's tides........ Yes, land moves also, we just see water more.
Something doesn't add up here.
and the ocean is lifted/dropped, causing immense change in pressure on the sea floor. All of these deltas are dependant on the precise distance from the moon, the sun, and other planetary bodies.
Add in the variables of the density and structure of the materials in the earth's surface, and the pressures they are being subjected to, and .... prediction is mostly a joke.
