stratovolcano: a steep-sloped, conical structure composed of alternating layers of hardened lava, solidified ash, and rocks thrown out by earlier eruptions.
The current stratovolcano-a cone-shaped volcano built from successive layers of thick lava flows and eruption products like ash and rock fragments-is built on top of an older stratovolcano.
