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 ...
Eddie crater, a central peak-ring crater on Mars. A central-peak crater is the most basic form of complex crater. A central-peak crater can have a tightly spaced, ring-like arrangement of peaks, thus be a peak ring crater, though the peak is often single. [3] Central-peak craters can occur in impact craters via meteorites.
Volcanic crater – Roughly circular depression in the ground caused by volcanic activity; Volcanic crater lake – Lake formed within a volcanic crater; Volcanic dam – Natural dam produced directly or indirectly by volcanism; Volcanic field – Area of Earth's crust prone to localized volcanic activity
Secondary crater chain of Copernicus in Mare Imbrium. Secondary craters may appear as small-scaled singular craters similar to a primary crater with a smaller radius, or as chains and clusters. A secondary crater chain is simply a row or chain of secondary craters lined adjacent to one another. Likewise, a cluster is a population of secondaries ...
Koko Crater is a tuff cone that is part of the Honolulu Volcanic Series. A tuff cone, sometimes called an ash cone, is a small monogenetic volcanic cone produced by phreatic (hydrovolcanic) explosions directly associated with magma brought to the surface through a conduit from a deep-seated magma reservoir. They are characterized by high rims ...
Although sometimes described as a crater, the feature is actually a type of sinkhole, as it is formed through subsidence and collapse rather than an explosion or impact. Compared to the thousands of volcanic eruptions that occur over the course of a century, the formation of a caldera is a rare event, occurring only a few times within a given ...
Mount Mazama (Klamath: Tum-sum-ne [5]) is a complex volcano in the western U.S. state of Oregon, in a segment of the Cascade Volcanic Arc and Cascade Range.The volcano is in Klamath County, in the southern Cascades, 60 miles (97 km) north of the Oregon–California border.
