More Fatal Earthquakes to Come, Warn Climate Change Scientists
Theres a volcano in Alaska, Pavlov, that only erupts during the autumn and winter. The 10cm or 15cm rise in sea level during the winter months, when low pressure comes over, is enough to bend the crust and squeeze magma out. Thats an example of how tiny a change you need, he said.
Meanwhile, geologists modelling the effect of retreating ice sheets in the northern hemisphere predict more volcanic activity as pressure is released on fault lines. McGuire points to three eruptions in five years in Iceland You cant say thats statistical proof but it makes you think. ..Some of McGuires colleagues believe he overstates the earthquake risk of sea-level rise and changing rainfall. There is just not enough data yet to prove the hypothesis, says Professor Burgmann. But he is convinced Maguire is right when he talks about volcanic eruptions.
Ice unloading at the end of the ice ages produced a flurry of volcanic eruptions. That makes sense to me its very true that if you take pressure off a magmatic system that can activate eruptions. Theres solid evidence of that in Iceland.

Nepal is so far from the nearest sea that sea level rise contributed ZERO

I spent six years studying subduction zone magma production and mantle melting processes.

I would think that the melting of all of that heavy ice MAY have an impact..
