Research in Seismology

Abstract

Seismic surface wave attenuation was found to vary significantly in different geographical regions of the earth, tectonic regions exhibiting greater attenuation than stable regions. Much of this variation is due to lateral variations of Q structure in the upper crust. For Iran, the attenuation of crustal seismic phases is similar to that of the western United States.
