Experimental Study of the Effects of Faults on Spherical Wave Propagation
Abstract
A laboratory technique has been developed for investigating the effect on a spherical wave of a fault located close to a spherical explosive charge that is detonated to generate the wave. The medium is a grout that simulates tuff, the fault is idealized by Mylar sheets, and the sensor is a particle velocity gage. The gage principle is based on Faraday's law in that a voltage is induced in a conducting loop when a moving portion of the loop cuts the flux lines of a magnetic field. A measure of the wave-fault interaction was obtained by comparing records of particle velocity gages engulfed by waves that have not crossed faults with records of gages engulfed by waves that have crossed faults. From these comparisons, it was concluded that the technique is suitable for investigating wave-fault interactions.
