Pelean Type Volcano:

Features:
- The Pelean type volcano, also known as a dome volcano, is characterized by its steep-sided cone shape and the presence of a lava dome at its summit.
- These volcanoes are typically found in areas where the magma is highly viscous and contains a high concentration of gas, which causes explosive eruptions.
- The lava dome, which is composed of thick, sticky lava, grows slowly over time as the magma pushes its way to the surface. This creates a steep-sided cone shape.
- Pelean type volcanoes often have a small summit crater that may be filled with a volcanic lake or a vent through which gases and ash are released during eruptions.
- They are usually surrounded by deposits of pyroclastic material, such as ash, pumice, and volcanic bombs, which are ejected during explosive eruptions.
- These volcanoes can have a variety of eruption styles, including explosive eruptions, lava dome collapses, and pyroclastic flows.
- Pyroclastic flows, which are fast-moving clouds of hot gas, ash, and rock fragments, are a particularly dangerous feature of Pelean type volcanoes. They can travel at high speeds and destroy everything in their path.
- The eruptions of Pelean type volcanoes are often highly explosive and can produce ash clouds that reach high altitudes. These ash clouds can pose a threat to aviation and cause respiratory problems for people living in nearby communities.

Visuvious Type Volcano:

Features:
- The Vesuvius type volcano, also known as a stratovolcano or composite volcano, is characterized by its symmetrical cone shape and alternating layers of lava, ash, and rock fragments.
- These volcanoes are typically found in subduction zones, where one tectonic plate is forced beneath another, causing the melting of rock and the formation of magma.
- Vesuvius type volcanoes are known for their explosive eruptions, which are caused by the high viscosity and gas content of the magma. These eruptions can produce pyroclastic flows, ash clouds, and lahars.
- The cone shape of Vesuvius type volcanoes is formed by the alternating layers of lava, ash, and rock fragments that are ejected during eruptions. The lava flows from these volcanoes are usually thick and slow-moving.
- These volcanoes often have a central vent or summit crater, which is the main outlet for the eruption of magma and gases. They may also have secondary vents or fissures through which magma can escape.
- The eruptions of Vesuvius type volcanoes can be highly explosive and produce large ash clouds that can travel long distances. These ash clouds can pose a threat to aviation and cause respiratory problems for people living in nearby areas.
- Vesuvius type volcanoes are often associated with volcanic hazards, such as pyroclastic flows, lahars, and landslides. These hazards can cause significant damage to both human settlements and the surrounding environment.
- Some well-known examples of Vesuvius type volcanoes include Mount Vesuvius in Italy, Mount St. Helens in the United States, and Mount Fuji in Japan. These volcanoes are closely monitored due to their potential for destructive eruptions.
