Abstract

Presented are the results of recent analyses of strong ground motion data from subduction zone earthquakes. Several new sets of attenuation relationships are presented for estimating peak horizontal accelerations and response spectral ordinates. These relationships were developed from regression analysis of recorded data augmented by numerical ground motion simulations. Attenuation relationships were developed for rock, shallow, and deep soil site classifications for both interface (plate boundary) and intraslab (Benioff) earthquakes.
