Why is Mt. Stromboli a composite?

Answer 1

Mt. St. Helens is considered a composite or Strato-Volcano due to the type of magma it erupts. The volcano is primarily composed of Andesite, a medium consistency magma. This medium viscosity magma makes it possible for both explosive and docile eruptions from the volcano. Although everyone remembers the May 18, 1980 explosive eruption, there is also much geologic evidence to support non-explosive lava extrusion type eruptions. However, due to the magma type that the volcano is primarily composed of, it is classified as a composite volcano with the typical steep sides, and potential for very explosive eruptions.

Answer 2

Mt. Stromboli is not a composite volcano; it is a stratovolcano. Stratovolcanoes, or composite volcanoes, are characterized by their steep slopes and explosive eruptions due to the high viscosity of their lava, which can trap gases and build up pressure. Stromboli is known for its frequent mild explosions and continuous low-level activity, rather than the large, explosive eruptions typically associated with composite volcanoes.

Answer 3

Yes. Mount Vesuvius is a composite volcano.

Answer 4

Mt. Stromboli is a composite volcano, because of its structure and composition. It is a conical volcano made up by numerous layers of hardened lava, pumice, tephra, and volcanic ash.

Answer 5

It is called that because the volcano is made up of different parts and elements.
