The deep earthquake ( h =650 km) that occurred on 11 April 2010 south of Granada, Spain, has been studied using the inversion body waves at teleseismic and regional distances. We have obtained a solution dip-slip motion either vertical plane or nearly horizontal with pressure axis dipping 45° to east. is chosen as rupture plane, propagating from east west basis directivity effects distances differences waveforms comparison these results focal mechanisms four other earthquakes in same area shows similar processes. origin this seismic activity remains an open question. Tomographic studies shown existence anomalous region extends 200- 700-km depth. olivine-spinel phase transitions shear melting along planes inside may be explanation for occurrence earthquakes.
