The geomorphology of volcanic provinces represents the long-term interaction of processes related to magmatism, tectonics, and climate. Within the subsurface, stresses associated with surficial loading, tectonic deformation, and magma accumulation drive topographic growth while influencing crustal magmatic networks. On the surface, volcanic activity alters regional-scale hydrology, sediment budget, lithology, and topographic stresses, competing with and driving erosion to influence landscape morphology and depositional preservation over 10-1000 kyr timescales.

Recognizing and understanding the interplay between surface and subsurface processes bridges the fields of geomorphology and volcanology, further progressing our understanding of hazards and shared research approaches. This session will explore recent advances in quantifying the surficial and crustal relationships that influence volcanic landscape construction and degradation at any spatial and temporal scale, both on Earth and other planetary bodies. We welcome research that addresses the evolution of volcanic terrains that span the interface of the subsurface and atmosphere.
