SEISMIC WAVE ATTENUATION CHARACTERISTICS AROUND TEHRI REGION

Abstract

This dissertation report will provide a brief insight into methodology involved in determining Seismic wave attenuation characteristics around Tehri region. The report also incorporates a new MATLAB software which can be used for further examination of attenuation characteristics for other regions. Seismic attenuation around Tehri region had never been studied in detail. This study would present the result of the seismic attenuation around Tehri region and wave attenuation characteristics, based on the data collected from the past earthquakes in the region. In this report a detailed explanation of attenuation characteristics of seismic waves around Tehri is given and factors which effect the attenuation characteristics is studied like scattering, intrinsic attenuation, multipathing, geometrical Spreading. The study of attenuation characteristics basically means the relationship among these factors. This dissertation hence tries to establish the procedure for determining attenuation characteristics for various regions.
