Mount St. Helens features a caldera, which was formed during the catastrophic eruption in 1980. The caldera is a large depression resulting from the collapse of the volcano after the explosive eruption, and it is distinct from craters, which are typically smaller openings formed by volcanic activity. Within the caldera, there are also smaller craters and vents that have formed due to subsequent volcanic activity.
What else can I help you with?
How many vent does Pinatubo have?
Mount Pinatubo in the Philippines has a vent known as a caldera, which is a large volcanic crater formed by the collapse of land following a volcanic eruption. So technically, it has one main vent - the caldera formed after the 1991 eruption.
Does mt Vesuvius have calderas?
Yes, Mount Vesuvius does have a caldera. The current cone of Vesuvius sits within the caldera of a much larger ancient volcano called Mount Somma. The collapse of Mount Somma's original structure formed the caldera in which the current Vesuvius cone grew.
What is the cuplike hollow around the vent of a volcano?
The central depression is called a crater, or more technically a "caldera."
Is mount St Helens a cinder cone?
No, Mount St. Helens is not a cinder cone but a stratovolcano. Stratovolcanoes have a steep profile and are built up by layers of lava, ash, and other volcanic materials. Cinder cones are smaller, simpler volcanoes formed by the accumulation of ejected cinders and volcanic ash around a single vent.
What mountain with a crater or a vent?
A mountain with a crater or a vent is typically a volcano. These geological formations are created by the accumulation of lava, ash, and other volcanic materials, often resulting in a circular depression at the summit known as a crater. The vent is the opening through which volcanic materials are expelled during an eruption. Examples of such mountains include Mount St. Helens in the United States and Mount Fuji in Japan.

What is the hollow area at the top of a volcano?
The hollow area at the top of a volcano is known as the crater. It is a bowl-shaped depression where volcanic activity occurs, such as eruptions, gas emissions, and lava flows. Craters can vary in size and depth depending on the type of volcano.
What is the slope of the mount st helens?
When first erupted from a volcanic vent, lava is a liquid at temperatures from 700 to 1,200 °C (1,292 to 2,192 °F). Over time the temperate will decrease as it moves away from the source.
What is a big crater where a volcano caved in called?
A big crater formed when a volcano collapses is called a caldera. It is typically much larger and deeper than the original volcanic vent.
What is the hole called that is caused by the explosion or collapse of the centre of a volcano?
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.
What is a circular depression formed by an explosion or a collapse at a volcanic vent?
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.
What steep sided usually circular depression formed by either explosion or collapse at a volcanic vent?
This is known as a caldera or a crater.
