Abstract
Three influences on physical modeling results of unstable dynamic displacements along fault edges under triggered relaxation. The fault filler is assumed to be quartz sand placed in-between moving tiff and rough plates. This quartz sand interlayer is subject to variation in compaction, to relaxation from stresses and to a burst air flow across the interlayer to simulate gas rush in the fault. The relaxation periods in the compact sand packing under the influence of the gas flow are determined.
