Golsar is located in north-west of Rasht the capital city of Guilan province. This region, according to standards 2800, is identified among the regions with relatively high risk of earthquake. A set of historical and instrumental seismicity data used in radius of 200 km which covers the period twelveth century until now. Kijko method has been applied for estimating for parameters considering of...

Gutenberg and Richter showed that magnitude-recurrence relationship may be represented by a linear relationship when the log of annual rate of exceedance was plotted against magnitude. This type of recurrence model has been in use because of its simplicity and because it fits the data reasonably well over a useful range of magnitudes of engineering interest. A quadratic log frequency relationsh...

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, ...

The response spectra defined in the appropriate Euro standards from first and second generation (EN 1998–1 EN 1998-1-1), which determine seismic load for common buildings, are critically presented first. To avoid a reduction earthquake loading on structures using spectra, only few points of 1998-1-1 determined by applying probabilistic concept hazard assessment. comparison current is made with ...

There are several significant seismological issues to consider in the analysis of soil structure interaction (SSI) effects of nuclear power plants (NPP). Typically, a seismic hazard analysis will be used to define free-field motions at the plant site; this paper therefore begins with an overview of seismic hazard analysis, with particular focus on stable continental regions such as eastern Nort...

We present seismic zoning maps of the National Capital Region (NCR) India in terms uniform hazard spectrum (UHS) amplitudes using three different attenuation equations to model contributions local earthquakes around region and distant northwestern Himalaya (NWH) Hindu Kush Subduction (HKS) sources. Our results show that shape design spectra must depend on nature contributing earthquake sources,...

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...
