Pit crater - Wikipedia
WEBA pit crater (also called a subsidence crater or collapse crater) is a depression formed by a sinking or collapse of the surface lying above a void or empty chamber, rather than by the eruption of a volcano or lava vent. [1]

WEBpit | crater | As nouns the difference between pit and crater is that pit is a hole in the ground while crater is a hemispherical pit created by the impact of a meteorite or other object.
Caldera or crater…what’s the difference? | U.S. Geological Survey
WEBJan 8, 2024 · The main point is that a caldera is bigger and a crater is smaller. Craters often form by small evacuations of magma from shallow levels, like the numerous pit craters that dot the surface of Kīlauea, in Hawaiʻi, whereas a caldera results by the partial emptying of a volcano’s main magma chamber.

Volcanic Craters - U.S. National Park Service
WEBPit craters are small craters that are usually steep-sided depressions formed from subsidence, or collapse. They form from the bottom up by progressive collapse over a void. At least 174 pit craters have been mapped in Craters of the Moon National Monument, with diameters ranging in size from 16 feet (5 m) to 1300 feet (400 m).
Crater - Education | National Geographic Society
WEBApr 17, 2024 · A crater is not the same thing as a caldera. Craters are formed by the outward explosion of rocks and other materials from a volcano. Calderas are formed by the inward collapse of a volcano’s magma chamber. Craters are usually much smaller features than calderas, and calderas are sometimes considered giant craters.

WEBJan 1, 2015 · Pit craters are rimless, circular to elliptical depressions that have steep inner walls, giving them a conical, bowl, or cylindrical shape, with or without a flat floor (e.g., Okubo and Martel 1998; Wyrick et al. 2004; Ferrill et al. 2011). Their diameter often increases with time via wall slumping.

WEBJul 15, 2020 · Pit Craters. Visible at many overlooks along Chain of Craters Road, pit craters are depressions that form primarily as the earth fractures when a volcano shifts or expands. They are characterized by steep walls and a roughly round or ovular shape, often slightly elongated parallel to rift zones.

WEBJan 1, 2014 · Pit craters are rimless steep-sided depressions that are inferred to have formed by collapse processes of volcanic/magmatic origin (e.g., Halliday et al. 2011 ). Some authors also include those of faulting origin (Ferrill et al. 2004, 2011; Wyrick et al. 2004 ).
