Theory of consolidation and precursory time of earthquakes

Abstract

Settlement of ground can be explained by Terzaghi's theory of consolidation in the field of soil mechanics. Terzaghi introduced the concept of strain to the consolidation equation in the theory. On the other hand, the diffusion-like equation for earthquake prediction can explain precursory phenomena such as crustal movement and electrical resistivity closely link to the relationship between magnitude and precursor time. However, the reason is obscure why derived from the diffusion-like equation in spite of given seismological impact. Accordingly, we noticed the void ratio from the point of view of consolidation rather than the equation by the concept of hydrostatic pressure. Therefore, this consolidation idea (to relate void ratio and dilatancy) can effectively explain the electrical resistivity composed in saturated ground. d c d v d p M qd d p     
