Quick Reference

A conical body of sand, resembling a small volcano, which is rarely more than a few metres wide and less than 50 cm high. Internally the sand volcano consists of a massive central plug, surrounded by laminated sand paralleling the external form. Sand volcanoes are formed by the extrusion of highly liquefied sand through a local vent in a confining layer at the surface.
