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.
Head crater is a small crater in Oceanus Procellarum on the Moon. The name of the crater was formally adopted by the IAU in 1973. [1] Apollo 12 astronauts Pete Conrad and Alan Bean landed the Lunar Module (LM) Intrepid northeast of Head crater on November 19, 1969. To the east of Head is the larger Surveyor crater.
The shaped charge is used to bore a hole for a cratering charge. A typical device consists of a solid cylinder of explosive with a metal-lined conical hollow in one end and a central detonator, array of detonators, or detonation wave guide at the other end.

Crater created by the Sedan shallow underground nuclear test explosion A flooded crater produced by the 2020 Beirut explosion.In a large explosion like this, the energy may not only cause destruction like that shown in the picture, but eject large amounts of material from the ground, creating a hole in the earth.
cratering rate relative to time is known. Photographs taken from notable lunar and martian missions have provided scientists the ability to count and log the number of observed craters on each body. These crater count databases are further sorted according to each craters size, depth, morphology, and location.
Head describes deposits consisting of fragmented material which, following weathering, have moved downslope through a process of solifluction. The term has been used by British geologists since the middle of the 19th century to describe such material in a range of different settings from flat hilltops to the bottoms of valleys. [ 1 ]
The crater Webb, as seen from Lunar Orbiter 1.Several smaller craters can be seen in and around Webb. Side view of the crater Moltke taken from Apollo 10.. Lunar craters are impact craters on Earth's Moon.
