SCALING RELATION OF SEISMIC WAVE ENERGY IN TERMS OF MAGNITUDE, DISTANCE AND SITE CONDITION

Abstract

As any earthquake occurs, a large amount of energy is released due to tectonic movement but as it is not the same when distributed in far distance areas, only a fraction of that part reaches to the considered location. So we are considering the energy which reaches the site and will cause damage to the structure. This seismic wave energy reaching considered site is advantageous over the earthquake intensities, arias intensity, PGA, PGV, PGD etc. because these factors are related to the energy at site which cannot be linked directly with the hazard. The wave energy reaching at site is calculated. Further for developing the relationship of this energy with magnitude, distance and site geology (soil depth) 42 earthquake data (229 earthquake records) are taken from PESMOS. After applying the base corrections to the data the random effect regression method is followed to develop the relations of energy with considered parameters.
