Like most stratovolcanoes, Mount St Helens alternates between explosive and effusive eruptions.
In its most recent activity Mount Etna has erupted basaltic lava. These eruptions have been mildly explosive and produced glowing red lava flows due to the lava's relatively low viscosity.
Vesuvius has had two main types of eruptions throughout its history: explosive and effusive. Explosive eruptions are characterized by the violent release of gases, magma, and volcanic ash, resulting in significant destruction and potential pyroclastic flows. Effusive eruptions, on the other hand, involve the relatively gentle outpouring of lava onto the surface, which can create lava flows and slowly build up the volcano over time.
the magma in vesuvius is felsic. this means that it is rich in silica and metals.
Mount Etna is a stratovolcano that sits on a tectonic fault line. The fault line runs from the Lipari Isles over the east coast of Sicily to the Hyblean Mountains.

it has pyroclastic flow and has small eruptions of ash.

It is not a composite volcano or a cinder cone volcano... it's not even a shield volcano so it is NOT one of the three main volcanoes
Magma is a hot fluid from deep within the Earth's crust. The set of magma conditions that produce the most explosive eruptions are high viscosity and the presence of dissolved gases.
