Aye but PACE is also correct that in geology terms they will happen in the next micro bit of time.
But to humans that can be a couple of life times.
I suspect though in this case something is going to happen sooner rather than later with this bad boy. That isn't a scientific observation just a gut feel.
I was trying to estimate the energy involved with the opposing forces ie weight of rock weight of ice etc. It just mind boggling how much there is sitting balanced at the moment. if it all goes at once its going to be one huge bang. Slowly through some sort of throttle maybe not to bad. But its got to go somewhere.
