A volcanic vent.
A bowl-shaped area that forms around a volcano's central vent is called a crater.
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.
