Revil A., Jardani A., Sava P., Haas A. The Seismoelectric Method: Theory and applications
John Wiley & Sons, Ltd., 2015. — 303 p. — ISBN: 9781118660263
At least as far back as the early 1930s, geophysicists were intrigued by the small electrical field disturbances that accompany propagating seismic waves and their potential utility in subsurface exploration. The first ever volume of the Society of Exploration Geophysicists’ flagship journal, Geophysics, was R. R. Thompson report, in 1936, on “The Seismic Electric” effect and its potential
value in recording seismic waves. Geophysicists have of course confirmed since then that there are better ways of recording seismic signals, and the “seismic electric” effect recurrently came into and went out of fashion as dictated by a healthy dose of skepticism that persists to this day. However, over the past three decades, the body of seismoelectric (electrical fields induced by seismic wave propagation) and electroseismic (seismic waves induced by electrical current flow) literature has been growing ever faster, reflecting ongoing academic intrigue and, in my mind, perhaps also the romantic notion that one day the Earth might reveal its innermost secrets by tiny electrical fields when it is gently prodded with seismic waves.
