Such an explosion can be modeled as a sudden increase in pressure inside of a finite spherically symmetric cavity. The explosion itself may produce a cavity by melting, vaporizing, and deforming the surrounding rock (underground nuclear explosions can produce 0.5-km-radius cavities in preexisting rock and shatter the surrounding rock).

An underground explosion produces a spherical cavity from combined vaporisation, melting and shock compression of the rock. From: Radioactive Waste …
