Abstract

Synthetic seismogram modelling and observations suggest that depth phases from local crustal earthquakes are of the type sX , where X stands for Pg, Pn , and the reflections from the crust-mantle boundary , mainly PMP and SMS. Depth phases of the type pX generally have much smaller amplitudes and are unlikely to stand out in seismograms . The differential times sX-X provide a very good control of focal depth. Examples of earthquakes that occurred in May and June 1991 in an area northwest of Kempsey (New South Wales) and in September 1991 near St George (Queensland) indicate that their foci were in the uppermost crust, at depths of between 2 and 3 km
