The Seismoelectric Effect in Rocks
In this chapter, we will consider a comparatively little-known electrical phenomenon observed in rocks — the seismoelectric effect. The seismoelectric effect is considered to be the development of a difference in potential between two adjacent points in a water-bearing rock when an elastic wave passes through it. The seismoelectric effect is an expression of the electrokinetic phenomenon which has been studied in colloid chemistry [1, 2]. Therefore, it is worthwhile considering the fundamental characteristics and mechanisms involved in the electrokinetic phenomenon, before attempting to understand the seismoelectric effect.
