What is a volcanic crater feature?

A volcanic crater is a large, basin-like depression at the summit of a volcano. It forms when the magma chamber beneath a volcano is emptied during an eruption, causing the overlying rock to collapse into the chamber. Craters can also be formed by explosive eruptions that blow out the summit of a volcano.

What is the crater of a volcano?

yes, I think so. because, very large volume of magma is ejected and then magma chamber can't support the volcano above it. then the volcano begins to sink into the earth.magma chamber empties and a new collapsed depression occurs.


What is the crater in a volcano?
