The short term effects of a volcano blast
include the hazard of the magma itself. Whether
lava flows, or air fall, or ash flows, the toxic
gasses emitted also are hazardous. Then, in the
longer term, there are some nutrients that go into
soil such as P (Phosphorus), Na (Sodium), K
(Potassium) that help the soil in the long.
Another effect is COOLING, which comes when big
eruptions put ash and gasses in the stratosphere.
This cooling happens because the S (Sulfur) gases
hydrolyze to form sulphuric acid aerosols, and
these tiny droplets reflect incoming solar
radiation. Is this reflection what keeps the earth
cooler by increasing its overall reflectivity
(less sunlight gets stored in atmosphere/oceans).
So, volcanic eruptions are good and bad!
On the other hand, natural ash in the
atmosphere makes for very dangerous conditions for
jet engines. A jet engine sucks in air, but if
that air has tiny particles (ash), these particles
can quickly FOUL the engine, which causes the loss
of thrust, and hence the plane crashes.
