Abstract: Presents research which observed electric potential variations and radon emanations associated with transient deformation events in the French Alps. Precursors for earthquakes; Fluid mechanisms in crustal deformation; Characteristics of deformation events in 1995; Deformation model in which straining induces fluid overpressure and dynamic flow in cracks; Sensitivity of rock transport properties to deformation.
