Response parameter is pseudo-velocity for 2, 5, 10 and 20% damping.
Most records from between 20 and 40km. No records from R < 10km so equation does not apply there.
Eliminate suspect and/or redundant (San Fernando) records.
Split data into intensity groups: VI (126 records), VII (56 records), V+VI (186 records), VI+VII (182
records) and VII+≥ VIII (70 records) and calculates coefficients for each group.
Note not adjusted for local site conditions. Try to distinguish effect but correlations do not reveal significant
variations. Notes very few records on hard rock.
