A volcanic crater is a bowl-shaped depression in the ground caused by volcanic activity, usually located above the volcano's vent. [11] During volcanic eruptions, molten magma and volcanic gases rise from an underground magma chamber, through a conduit, until they reach the crater's vent, from where the gases escape into the atmosphere and the magma is erupted as lava.
A volcanic crater is an approximately circular depression in the ground caused by volcanic activity. [1] It is typically a bowl-shaped feature containing one or more vents. During volcanic eruptions , molten magma and volcanic gases rise from an underground magma chamber , through a conduit, until they reach the crater's vent, from where the ...
Impact crater: a depression created by an impact, such as a meteorite crater. Sedimentary-related: Sedimentary basin: in sedimentology, an area thickly filled with sediment [1] in which the weight of the sediment further depresses the floor of the basin. Structural or tectonic-related:
Crater Lake actually started as a mountain, Mount Mazama. A volcanic eruption roughly 7,700 years ago caused the mountain to collapse inward over time, forming a volcanic crater, the park says.

A volcanic crater lake is a lake in a crater that was formed by explosive activity or a collapse during a volcanic eruption. Formation
Immediately after an impact event, the falling debris forms an ejecta blanket surrounding the crater. An ejecta blanket is deposited in the interior regions of the crater rim to the final crater rim and beyond the crater rim. [2] Approximately half the volume of ejecta falls within 1 crater radius of the rim, or 2 radii from the center of the ...
When considering the mean, or average depth of lakes, Crater Lake becomes the deepest lake in the Western Hemisphere and the third-deepest in the world. Crater Lake Institute Director and limnologist Owen Hoffman states that "Crater Lake is the deepest, when compared on the basis of average depth among lakes whose basins are entirely above sea ...
