The majority of volcanoes exist throughout the Pacific ‘ring of fire’ although volcanoes do occur at any location where tectonic plates are either converging or diverging. The volcano is essentially a break in the earth’s crust at these points.
The effects of a volcanic eruption can differ. They can be simple eruptions of steam outflow and minor gas discharge, or they can be massive explosions which release tremendous amounts of gases, lava, rocks, and volcanic ash. Such large eruptions can cause considerable amounts of damage, affect the health of people and lead to them being evacuated if an eruption is deemed to be imminent.

Both conventional weapons and nuclear weapons rely on a blast or shock wave as their destructive force. The difference of course is that due to the massive release of energy associated with a nuclear weapon, the explosion can be millions of times more powerful than that of a conventional weapon.
Due to the large amount of energy released by a nuclear weapon, heat and light energy are emitted in the form of thermal energy, and the temperatures reached are much higher than with conventional weapons.
