Does the frequency / strength of earthquakes leading up to an eruption have any bearing on the explosiveness of the ensuing eruption?

- colechristensen 3y agoThe explosiveness has more to do with the composition of the magma. Magma high in silica is thicker and doesn’t offgas as readily which leads to more gas explosions with pent up pressure. Magma lower in silica explodes much less because the gas bubbles out instead of building up.
