volcanoes that have large amounts of silica
The most explosive volcanoes are stratovolcanoes with felsic magama that has a high gas content.
A. Shield Volcano- these usually form at hot spots and are like the ones in Hawaii. THey are nonexplosive because the lava is very runny. This would not be the most explosive. B. Cindercone-this would probably be your best bet although they erupt only once during their liftime. They are the smallest type of volcano and have steep sides. When it explodes, it shoots out pyroclastic material. C. Composite Volcano-this is also called a stratovolcano. It has both nonexplosive and explosive eruptions. THey can have many eruptions. IF the cinder cone was not what you were looking for, then this would be your second choice.

Parasitic cone volcanos and cinder cone volcanos are not the same when classifying. Cinder cone volcanos are the most popular type of volcano, named for its cone shaped formation. Cinder cone volcano are also considered the smallest type of volcanos and can stand alone or grow on the flanks of other volcanos. The parasitic cone volcanos are similar to the cinder cones, however, the volcano is found on the flanks of other volcanos, hence, the name. It is created by flank eruptions of larger volcanos.
A subduction zone is the area where an oceanic plate is being pushed downward in a collision with a continental plate. There is usually an offshore trench and several inland volcanos whose eruptions are of the explosive type (due to trapped water in the lava). Another form of subduction zone produces island arcs containing volcanos instead of producing inland volcanos.
Large explosive eruptions are generally characteristic of stratovolcanoes.
Many have rhyolitic magma, which is high in silica. Magma with higher viscosity and higher gas content is the most explosive when released.
Volcanoes come in many types, such as scoria volcanoes (mafic, small, not very explosive),shield volcanoes (large, mafic, mild eruptions of large volumes of lava), composite volcanoes (large, traditional cone shape, most deadly), lava domes (felsic, explosive, usually found with other volcanoes), fissures ( lava erups through fractures, mafic), and canderas (steep-walled depression, very large).
The most common type of volcano is the cinder cone volcano. I did a report on it. . . i should know.
Cinder cone volcanos have steep sides and broadd bases.They are formed by explosive eruptions that are followed by lava outpourings.

Non-explosive and Explosive
The most explosive and violent fires are wind driven fires. This usually occurs when there are sun downer winds that are driving the fire violently out of control.
