A large number of seismic observation data and macroscopic survey earthquake damage indicate that soil site may amplify the intensity ground-motion thus aggravate to structures on site[1]. The influence response ground motion is one most important topics in engineering. methods predicting effects can be divided into two groups with respect theoretical empirical methods. are analyse based theory...

The past decade has seen great advances in the understanding of how strong ground motions scale with various independent (source, path and site) parameters and increased sophistication in the modelling of these effects in ground-motion prediction equations (GMPEs). In parallel there has been considerable progress made in modelling and quantifying the various components of aleatory variability (...

during the past decades, attempts have been made to develop an early warning system for coming destructive earthquakes a few seconds before the ongoing ground motion. in this paper, a practical method for the early warning of earthquakes in south iran is presented. this region is selected for study because it has high potential for generating earthquakes and has a more complete strong ground mo...

Probabilistic Seismic Hazard Assessment (PSHA) was carried out for the administrative region of Attica (Greece). Peak Ground Acceleration (PGA) and Velocity (PGV) values were calculated return periods 475 950 years five sub-areas covering entire region. PGA hazard curves Uniform Spectra (UHS) in terms spectral acceleration (Sa) generated Athens, Methana, capitals each island (Salamina, Aegina, ...

Recorded ground motions in near fault region have completely distinct nature from others that recorded in far field of the fault. Near source outcomes cause much of the seismic energy to appear in a single large and long period pulse at the beginning of the velocity record. Assaluyeh complex is located near the reverse Assaluyeh fault that is a segment of Mountain Front Fault. This complex cont...

In India, the frequency of occurrence of earthquakes is more, especially in Himalaya, northeast India and Gujarat region. Therefore it becomes essential to estimate the seismic inputs for such earthquakes to reduce the structural damage. From engineering point of view, the most sought-after data is the strong motion accelerograms (SMA), recorded in the places where earthquake has occurred. The ...
