In geology, a Steam-burst fracture refers to a type of fracture (a crack or break) in rock caused by the rapid expansion of steam or heated fluids within the rock mass. This can occur due to various geological processes, including volcanic activity, geothermal systems, or even rapid heating of rock during landslides. These fractures can significantly alter the rock’s mechanical properties and influence fluid flow within the subsurface.
