Lava cave

Classic lava tube passage in Lava Beds National Monument, California, USA

A lava cave is any cave formed in volcanic rock, though in typical use it usually means caves formed by volcanic processes, which are more properly termed volcanic caves. Sea caves, and other sorts of erosional and crevice caves, may be formed in volcanic rocks, but are unrelated to volcanic processes and typically form long after the volcanic rock was emplaced.


There are many types of lava caves, with these being the most notable:

  • Ice caves Some lava tubes are referred to as ice caves because they contain ice within.[3]
  • Liftup caves are related to pressure ridges and the inflationary process. Liftup caves can form on the edges of pressure ridges or pressure plateaus. When the concave edge of a ridge or plateau begins to expand outward it commonly leaves a void. Liftup caves are usually no more than 5–10 feet (1.5–3.0 m) though longer ones have been discovered up to 30 ft (9.1 m) long.[6]
