- Experiment Name: Characterization of the Superstition Hills Fault,
Southern CA, Using Trapped Waves
- PI: Li
- Email: ygli@coda.usc.edu
- Sponsor: USGS
- Inst: USC
- Start_Date: 10/1/2000
- End_Date: 12/15/2000
- Lat: 32.75
- Long: -115.75
- Chan3: 60
- ShortPeriod: 60
- Multi_Chan: 2
- 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.
