at the epicenter (r = 0) in the attenuation relations for PGX, a revision of model A
was examined, where R(r,M) is used, rather than just the epicentral distance, r. The model
considered is the following:
log10(PGX) = a·log10 ( R(r,M) ) + b · M + c (1)
with R given by:
gMkrR 10⋅+= , (2)
and where r is the distance from epicenter to the point of measurement, k is a parameter to be
fitted and
g
