Earthquake induced resonant motion of alluvium

Abstract

Earthquake accelerograms at two separated sites are spectrum analysed. Resonant motion is observed which is unidirectional at each site and correlated between sites. The directions of the resonant motions together with their coherence require a new dynamic model for alluvial regions.
