Shallow underground target detection using seismic-electric effects

Gal's research is focusing on understanding the physical mechanism of the seismic-electric effect in different soils, rocks and fluid content. This is needed in order to assess what are the attributes we can investigate using the seismic-electric method.

Seismic-Electric prospecting has its drawbacks. The electric field signal from seismic-electric response is very small (E~10nV/m), and requires sensitive sensors and low noise acquisition equipment. The different propagation speed of the seismic and electromagnetic waves requires different experimental setups for placing the sources and receivers.

The research aims to integrate seismic-electric prospecting for practical usage for shallow target detection in Israel. Our preliminary work showed feasibility for such usage. We examined different experimental setups for shallow target detection and measured sensor and acquisition system noise, where seismic-electric signal was detected. These promising preliminary results, encourage to improve the system used and to explore the applicability of the seismic-electric method.
