  observed on broadband         
  displacement seismograms,     
  with at least two events      
  occurring about 5 seconds     
  apart, observed on            
  broadband displacement        
  seismograms. Depth from
  synthetics of broadband
  displacement seismograms
  based on first event.       
  Apparent Stress       0.22 MPa
