Answer: Based on the description provided, it sounds like the volcano in question is a stratovolcano, also known as a composite volcano.
Step-by-step explanation:
Stratovolcanoes are characterized by having viscous magma that can produce pyroclastic flows (flows of hot ash, gas, and rock) and are made up of layers of ash, lava, and rock. Stratovolcanoes are often cone-shaped and can be quite tall. They are formed through the accumulation of material ejected during eruptions, and they are typically found along plate boundaries where tectonic plates are converging. Some well-known examples of stratovolcanoes include Mount St. Helens, Mount Fuji, and Mount Vesuvius.
