Question

What type of volcanic eruptions seem to occur most often "where plates are crunching together"?

Answer 1

Seismic Eruption, an earthquake in a volcanic area.

Answer 2

Actually, the most frequent are where plates are diverging or moving apart.  The mid-ocean ridge or rifts are good examples.  As the plates separate, mantle material moves upward as magma and fills in the void.

Answer 3

um I can't remember!!

Answer 4

If you are asking what type of volcanism is related to subduction (Plates crunching together) then the answer is strato volcanoes, that is explosive volcanism that is the result of the high vapour content and high viscosity of the magmas generated above subducting plates, as distinct from the quieter, effusive volcanism that occurs on spreading ridges and above oceanic mantle hot spots where the magmas are less viscous and hotter, so flow more easily.
