Approximately 56% of 60 known nested calderas are pairs of nonintersecting subcircular structures with similar eccentricities. The consistent configuration suggests an interdependence in the formation of the two annular ...
Resurgent doming consists of the uplift, usually accompanied by volcanic activity, of part of a collapse caldera. Analogue models were used to investigate the architecture of resurgent domes. Dry sand simulates the brittle ...

The structure and shape of collapses and resurgences is often controlled by pre-existing discontinuities, such as normal faults in rift zones. In order to study the role of extensional structures on collapse and resurgence, ...
