Fault-plane solutions based on first-motion polarities (see Table 6). All stereographs are lower hemisphere, equal-area projections. Solid circles correspond to compressive first motion (up); empty circles correspond to dilatational first motion (down). Full waveform moment tensor solutions are shown as beach-ball symbols for the two largest events where high quality fits are obtained
