It is commonly called a hierarchy.

In the UK the sidewalk is commonly referred to as the pavement.
It is called an arrowhead or, less commonly, a delta.
It can but that's not necessary. If it has, then that rhombus is commonly called a "square".
The circular bowl at the top of a volcano is called a "crater." It is formed as a result of volcanic activity, such as eruptions or collapse of the volcano's summit. Craters can vary in size and shape depending on the type of volcano.
A bomb that does not explode is called a dud. Sometimes it is called a fizzle. If it was a test shot it is commonly called a misfire.
These are called composhit volcanoes or stratovolcanoes.
The hole that is formed by the eruption or collapse of the central vent of a volcano is called a caldera. A caldera is typically much larger in size compared to the original volcanic crater and can be several kilometers in diameter.
Volcano bombs are lumps of half-melted, half-cooled balls of lava that is hurled out of a volcano. They are called volcano "bombs" as since they explode into flames on impact.
Pelean eruptions are most commonly seen at stratovolcanoes, which can also be called composite volcanoes.
The rare phenomenon you're talking about is called a calderas.Caldera is the term given to large depressions associated with volcanoes that form when volcanoes explode or collapse into the earth.
A caldera volcano is formed through the collapse of the summit of a volcano after a large eruption empties the magma chamber beneath it. This collapse creates a large crater-like depression called a caldera.
Magma that has reached the surface is called lava. It can flow or explode out of a volcano during an eruption.
When a volcano collapses into itself at its top, it forms a large crater called a caldera. Calderas are formed when the magma chamber of a volcano empties during an eruption, causing the summit to collapse inward.
Caldera.
The basin-shaped crater at the top of a volcano is called a caldera. It is typically formed after a volcanic eruption causes the volcano to collapse inward, creating a large depression. Calderas can range in size from a few kilometers to tens of kilometers in diameter.
