it is called a crater
Caldera.
the bowl shaped opening of a volcanoe is a crater
The opening of the volcano is called crater. A crater may be large in dimension or deep. This is where the magma erupts.
The opening at the top of a volcano is called the "vent." This is where magma, gases, and ash escape from the volcano during an eruption. The vent may lead to a larger crater, which is the bowl-shaped depression that forms around the vent after eruptions.
Any place the volcano opens up is called a vent since it allows for the release of built up heat and gas. The main summit of the volcano is usually called the crater but I'm guessing there is probably something more technical that a geologist would call it. Hopefully this helps.

composite volcano
The opening of the volcano is called crater. A crater may be large in dimension or deep. This is where the magma erupts.
The basin shaped crater at the top of a mountain is called a caldera. It forms when a volcano collapses into itself after an eruption, creating a large, circular depression.

Vent .
The term for the circular depression at the summit of a volcano is called a "caldera." It is formed by the collapse of the central part of the volcano after a massive eruption has emptied the magma chamber beneath it. Calderas can vary in size and shape depending on the volcano.
The large circular depression at the top of a volcano that forms when the roof of the magma chamber collapses is called a caldera. Calderas can be huge in size and are formed during explosive volcanic eruptions or when the magma chamber empties and the summit collapses into the void left behind.
If you look at the volcano side ways that little curve on top is called a cradle i think
The name of the hollow landform, found at the top of the volcano is called crater.
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.
