000015246 520__ $$2eng$$aWe report on unprecedented filll-field measurements of spontaneous dynamic ruptures in a unique laboratory earthquake setup. These measurements are enabled by the development of a new technique, which combines ultra-high—speed photography with the digital image correlation method. Earthquakes are mimicked in the laboratory by dynamic rupture propagating along the inclined frictional interface of an analog material, prestressed in compression and shear. This experimental setup has been successfully used in the past to study key rupture features but the previous diagnostics was not capable of quantifying the full-field rupture behavior. In this paper, we discuss our experimental measurements of full-field displacements, velocities, strains and stresses,obtained by using our novel methodology. One important application of this technique is to image the evolution of dynamic friction and study its dependence on slip or slip velocity.
