- Ground-motion model is: where Y is in cm∕s2, a = 0.72, b = 0.44, d = -0.00231, h = 4.5 and σ = 0.28.
- Records from soil or alluvium sites.
- All records corrected.
- Note that scatter can be reduced by increasing number of records used (especially in near field), improving
all seismological and local site parameters and increasing number of variables (especially in near field and
those modelling local site behaviour) but that this requires much more information than is available.
