Abstract
A structure is isolated from a seismic event by inducing soil liquefaction in an isolation layer beneath the structure and soil foundation zone, such as by activating an electro-osmosis gradient toward the isolation layer, during the seismic event, based on detection of movements associated with the seismic event.
