Explosiveness
The explosiveness of an observed volcanic
eruption is estimated by the calculated force of
the eruption. Experiments have shown that water
comes in contact with hot magma, the eruption is
much stronger- this is knowm as hydro-volcanism.
dor pre-historic eruptions, the explosiveness is estimated
by the degree of fragmentation of small volcanic particles.
Amore explosive eruption will "shatter" volcanic tephra
much more than a less explosive eruption.
