My research involves the understanding of how earthquake waves propagate through soil and rock. By combining seismology with engineering, we can estimate how much the soil or rock may tend to amplify or attenuate the earthquake shaking as it moves up from the bedrock to the ground surface. We can also predict whether or not the earthquake shaking will cause slopes to fail and soils to liquefy. My research includes measuring the dynamic response of naturally occurring soil and rock deposits, as well as the dynamic response of man-made structures such as earth dams and mine waste impoundments. With this information, we can develop designs that will keep the public safe.
