Descr: We shall deploy 48 PASSCAL REF TEKs with 2Hz 3-component L22 sensors in 4 linear seismic arrays across and along the Superstition Hills fault that ruptured in the 1987 M6.6 earthquake and the Superstition Mountains fault that was not broken in the 1987 event. We shall record fault zone trapped waves generated by near-surface explosions to be detonated within the fault zone. After explosions, we shall remain in the field for ~2 months to record trapped waves from microearthquakes. The trapped wave data will be used for characterization of the Superstition Hills rupture zone related to the dynamic ruptu;re process during the 1987 earthquake.
