ƒ^ƒCƒgƒ‹i‰pjF SPECTRAL AND AMPLIFICATION CHARACTERISITICS IN SAN SALVADOR CITY (EL SALVADOR) FOR UPPER-CRUSTAL AND SUBDUCTION EARTHQUAKES
´˜^i‰pjF An attempt is made in order to study the strong motion characteristics for upper-crustal and subduction destructive earthquakes in San Salvador City. Horizontal elastic response spectra for 5% damping and the site amplification factors are obtained to confirm the seismic microzonation, which has been proposed by an Italian mission in 1988, after the earthquake disaster of October 10 th 1986. Besides, the predicted spectral ordinates from available attenuation relationships for Central America are compared with the spectra of observed records at the specific sites. A brief discussion is made regarding with some microtremors measurements at strong motion stations.
