Abstract
An earthquake mechanism is described which operates when a liquid is present within a non-homogeneously stressed solid. Earthquakes are described which show distributions of P-wave compressions and dilatations which are consistent with the new mechanism and are inconsistent with shear fracture as the mechanism at the source.
