When the side of a volcano collapses, it is referred to as a volcanic landslide or a volcanic collapse. This can occur due to various factors, such as the eruption of magma, the weight of accumulated volcanic materials, or the destabilization of the volcano's structure. Such collapses can lead to pyroclastic flows, ash clouds, and significant hazards to nearby areas. The most notable example of this phenomenon is the 1980 eruption of Mount St. Helens in the United States, which involved a massive landslide.

When a volcano collapses, it can form a crater or caldera. A crater is a bowl-shaped depression at the top of the volcano, while a caldera is a much larger depression that can form when the center of the volcano collapses. Both features can result in a large, empty space left behind by the volcanic activity.
When a volcanic cone collapses it forms a caldera.
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.
A form of volcano that collapses in on itself is called a caldera. This occurs when a volcano erupts and empties its magma chamber, leading to a significant loss of structural support. As a result, the ground above the emptied chamber collapses, creating a large depression. Calderas can be quite vast and may eventually fill with water, forming lakes.
The large hole at the top of a volcano is called a "crater." It is formed when explosions or collapses create a depression at the summit of the volcano.
yes it is true
When the roof of a volcano collapses, it can form a large crater known as a caldera. Calderas are circular depressions usually larger than the original volcanic vent and are often filled with water or subsequent eruptions.
