Time-scale invariances in preseismic electromagnetic radiation, magnetization and damage evolution of rocks

We investigate the time-scale invariant changes in electromagnetic and mechanical energy releases prior to a rock failure or a large earthquake. The energy release processes are caused by damage evolutions such as crack propagation, motion of charged dislocation, area-enlargement of sheared asperiti...
