Fig. 5: Conceptual illustration of dissolution cavity collapse (DCC).

a Oblique view illustrating the process of warm solution mining (based on Collet et al.)66. b–d The relationship between mining activity, subsurface disturbance, surface deformation, and earthquake-triggered surface ejecta. Note that this conceptual illustration shows only one possible expression of cavity space; in reality, a variety of cavity manifestations are plausible, ranging from many micro-scale cavities (essentially, an increase in pore space) to a single macro-scale void (as depicted here).
