The accelerograms for western Canada are in the zipfile westacc.  Each filename refers to region, magnitude, site class and set (near or far).  Thus west6c1.acc has the accelerograms for the east for M6.5, on site class C, for set 1 (distance 10-15 km). Records are provided for magnitude 6.5 and 7.5 for the west, as well as Cascadia records for M=9.0.  The parameter Fdist in each column gives the closest distance to fault for that record.  There are 45 records per file, which can be used as either 15 3-component sets, or 45 random horizontal components.  

The corresponding response spectra values for each file are in the zipfile westpsa, using the same filename convention, but with extensions *.psa for response spectra.  Response spectra are 5% damped pseudo-acceleration.

All accelerograms and PSA values are in cm/s^2.
