Volcanoes are openings in the Earth’s crust, caused by the pressure of magma underneath the surface, usually from the collisions of tectonic plates in Earth’s crust.
Volcanoes are very powerful, with two types, those causing red eruptions, with liquid magma (lava) oozing from the volcanic opening, or those causing gray eruptions, which are powerful explosions of ash and pumice into the atmosphere.
Photographing active volcanoes can be quite dangerous, with hot lava, noxious gases, and sudden eruptions that can kill almost instantly. However, the results are beautiful when they are photographed:
