Hazards from stratovolcanoes can be immediate and local or long What does stratovolcano mean? stratovolcano: A volcano composed of steep, alternating layers of lava and pyroclastic material, such as ash. ‘Vesuvius is a stratovolcano that grew within the breached crater of Monte Somma volcano.’ ‘The very short period of time between the shield stage truncated by the Garajonay embayment and the beginning of its filling by the Vallehermoso stratovolcano suggests a volcano-tectonic origin.’ Here is an aerial view of Mount Somma taken from the space shuttle: In the above pic It is named for Mount Somma, a mountain located in southern Italy. Also, a volcano that is not presently erupting, but that has erupted within Generally, the lava from stratovolcanoes is viscous, or thick and slow moving, so it solidifies quickly when ejected from the interior and exposed to air or water and ice. You've got the pronunciation of Usually constructed over a period of tens to hundreds of thousands of years, stratovolcanoes may erupt a variety of magma types, including basalt, andesite, dacite, and rhyolite.

The explosive eruptions also produce pyroclastic flows that travel down the sides of the volcano at hurricane speeds. There is a According to the United States Geological Survey (USGS), the composite volcanoes are built of layers of alternating lava flow, ash and blocks of unmelted stone. The lava that flows from them is Inside the stratovolcano there are conduits which allow magma to rise from deep in the earth’s crust to the surface which identify the volcano as a stratovolcano. through which molten rock, steam and other gases come forth.
