Why Rotation Seismology: Confrontation between Classic and Asymmetric Theories

R. Teisseyre

A confrontation between the Classic Elasticity and Asymmetric Continuum Theory is presented in order to indicate the abilities of the two approaches and their deficiencies. The role of independent strain and rotation waves is discussed and some related particular examples are given. Our consideration may answer the question why the new theoretical approach might be important in a search for new earthquake precursory signals.
