Present work determines the seismic wave attenuation characteristics in the Garhwal Himalayan, India. These are obtained based on the attenuations of P, S and coda wave spectra from the recorded seismograms of nearby earthquakes (EQs) with focal depth up to 10 km. Since P and S waves come directly to the site, attenuation of P […]

Present study aims at understanding the seismotectonic province of the Shillong Plateau (SP) by identifying the potential seismic source zones within a radius of 500km from the centre of the SP. From existing literature and earthquake (EQ) data the seismotectonic region is found to vary in terms of seismicity, tectonic features, geology, thickness of […]

Characteristics of ground motions generated during an earthquake (EQ) alter between bedrock and the surface depending upon subsoil properties. Such modifications in the ground motion characteristics are termed as local site effects. Building response as well as induced effects of EQs are thus controlled by these modified ground motions at the surface. Hence, addressing the […]
