Motions at a Site
relationship is used to calculate peak ground acceleration and horizontal
spectral accelerations and is valid for moment magnitudes 4 to 9.5, distances
1 to 100 km, and depths 1 to 150 km.
The distance rrup
is defined as the closest distance from the site to the rupture surface.
where ZT = depth in km
