Neal-Field Synthetic Seismograms Taking into Account the Effects of Anelasticity ‘The Effects of Anelastic Attenuation on Seismograms Caused by a Sedimentary Layer’

Abstract

Recently, many seismologists have been analyzing the fine rupture process of earthquakes by the use of strong motion seismograms recorded near the source regions. Not only long-period waves, but also waves of periods less than several seconds are found to play an important role when analyze the detail of rupture processes. On the other hand, amplitudes and forms of seismic waves are strongly influenced by anelastic properties of the earth. In this paper, synthetic displacements are calculated on the surface of an anelastic layered half—space in order to estimate the effect of attenuation on the short period waves near the source region. © 1985, Japan Meteorological Agency / Meteorological Research Institute.
