Non-Double Couple Earthquake Mechanisms in Volcanic Environments

  • Geoffrey R. Robson
Part of the IAVCEI Proceedings in Volcanology book series (VOLCANOLOGY, volume 3)


Earthquake mechanisms involving movement of pore fluids accompanying tensile and shear failure in volcanic environments are described. Three mechanisms: extension failure, extension-shear failure and shear failure are identified. The role of pore fluid pressure in determining the type of failure mechanism is described and the factors which determine the relative frequency of occurrence of the three types of failure are commented upon.
