High-frequency velocities are measured during stick-slip motion in the immediate vicinity of a fault in a granite sample to reveal the microscopic process taking place in the breakdown zone defined in the slip-weakening model. It is found that 1) the onset time of the observed strong motion approximately coincides with the local rupture onset time, 2) the observed near-fault high-frequency.

A fault surface or a fault zone can act either as a conduit or a barrier for groundwater depending on the permeability of the material in the fault and on either side of the fault. If breccia is present it serves as an excellent conduit for water but if thick gouge zone with clay minerals is present, it serves as a barrier to flow of water.
