Volcanoes are named from the Roman god Vulcan who is said to wield power over the fires of volcanoes. Volcanoes are pressure valves that release energy from deep inside the Earth, beautiful, shocking, but deadly. Volcanoes are an example of viscous powers that continuously shape our planet.
The stratovolcanos are built from layer upon layer of mostly viscous magma, have relatively steep side, and can grow to great heights. They have the potential for violent eruptions.
-Mt Fuji and Mt Pinatubo, two volcanoes that you will see on this tour, are both stratovolcanoes.

Cinder Cone volcanoes are relatively small, usually less than 1,000 feet high, with very steep sides and a cylindrical shape. They are built from piles of ejected rock fragments. When they erupt, the lava flows not from the summit, but from a breach in the side or at the base of the volcano.
-Mt. Krakatoa, a volcano you will visit, is a cinder cone volcano.

Shield volcanoes, are massive structures with broad, gently slopping sides that usually build up from the sea floor. They are the largest volcanoes on Earth, built upon layer and layer of fluid, runny lava that can flow long distances before cooling. Shield volcanoes are island builders.
-You will not see any shield volcanoes on this tour, but an example of one would be, Mauna Loa in Hawaii, which is this here example image. |
