Edgecumbe earthquake

Some notes on its source, ground motions, and damage in relation to safety

Abstract

This paper first describes the basic features of the earthquake, its size, causal mechanism, and fault rupture characteristics, and distribution of felt intensities. The ground motions measured in various places are described in terms of accelerations, response spectra and attenuation. Finally safety aspects are discussed in relation to damage levels, strength of shaking and current code loading requirements.
