Abstract

A method and system of preventing soil liquefaction beneath a structure during an earthquake event, by monitoring local seismic precursor events, such as early arrival ground motion using an accelerometer, predicting the onset of a major earthquake tremor, and energizing conductors in the ground by a d-c power source for moving the ground water by electro-osmosis away from the foundation of the structure or to a series of pressure relief wells, whereby lowering the soil pore water pressure and preventing liquefaction of the soil beneath the structure.
