A Volcano that spawns a new cone, partially filling its caldera, is called, a somma volcano. When the new cone outgrows the original caldera, it is given a name of its own. It is the original volcano, the underlying structure, that is known as the somma volcano. These can be, and often are, stratovolcanoes themselves.
Mt. Vesuvius is a stratovolcano (periodic, explosive eruptions and a steep profile) It is a steep conical volcano. Its structure has been built up of solidified lava, pumice, and ash, one layer at a time: a legacy of all the eruptions of the volcano over time. Because of its layered structure, it is also known as a composite volcano, a subtype. Lastly, because it began as a new cone that partially filled, then filled and overflowed an existing caldera), in this particular case, that of Mt. Somma,* it is commonly, though erroneously called, a somma volcano, but the somma volcano is really the structure that underlies the new structure, a sub-subtype.*This is the namesake of all such volcanoes. Now all volcanoes that spawn new cones, partially filling their calderas, are called, somma volcanoes. When the new cones outgrow the old calderas they are given names of their own. Then, the underlying structure remains the somma volcano.
Tyatya is one of the finest examples anywhere in the world of a somma volcano, a stratovolcano whose summit has collapsed to form a caldera which has then been mostly refilled by a new, younger volcanic cone which rises above the caldera rim.
The arenal volcano is a cindercone volcano not a composite.
