Sit back, a 4th eruption maybe about to happen.

The solar/cosmic ray hypotheses are fascinating,and I'll continue to explore those as time permits.Thanks!
Something which did pass by had to do with water.
*There are hydrated serpentine antigorite rock,which in subduction zones,disintegrate into forsterite and enstatite under terrific friction-pressure-induced heating,at depths up to 200-kilometers,which liberate 13% H2O by weight,which in turn,ascends into the hotter,overlying mantle where it can cause partial melting in source regions of calc-alkaline magma.
*The calc-alkaline magma gives rise to subduction-related volcanism.
