Research ArticleOpen accessIn the author namesDelineate Location of the Last Earthquake Case Study NW of IranHadi JarahiThe earthquake hazard is most important title in seismic design of buildings. One of ways to know this hazard is to know where the earthquake boundary is. Moreover, understanding of the future earthquakes location, can help to modify the seismic hazard maps. The b-values, is the effective parameter on future earthquake positioning. This study was conducted to variations of b-values … …Current Research in Geoscience, Vol. 7, Issue 1 · 20 May 2017 · 8,173 accessesView PDF Cite

Research ArticleOpen accessIn the author namesProbabilistic Seismic Hazard Deaggregation for Karaj City (Iran)Hadi JarahiIn this study the results of PSHA deaggregation for 5%-damped 0.2, 0.5, 2 and 4 s spectral accelerations, corresponding to Mean Return Periods (MRPs) of 50 and 475 yr for Karaj city was presented. The aim of this paper is to quantify the dominant events that have the most contribution on ground-motion exceedance from the above mentioned hazard levels.
