Research ArticleOpen accessDamavand Earthquake of 2020 the Mainshock or an Alarm for Disaster for the Capital of IranMilad Baftipour, Hadi Jarahi, Gulten Polat, Sedigheh SeifilalehOn 7 May 2020, the Damavand earthquake with magnitude 5.1 occurred at 55 km east of Tehran city, which has a population of over 15 million people. This earthquake caused a seismic hazard for the capital of Iran. In this study, this earthquake was assessed to understand whether it will cause any seismic disaster. There is a doubt about the … …American Journal of Engineering and Applied Sciences, Vol. 15, Issue 1 · 14 Feb 2022 · 7,055 accessesView PDF Cite

Review ArticleOpen accessPSHA Study Using EZ-Frisk Software Case Study Baychebaq Dam SiteHadi JarahiAwareness of seismicity, is the earliest requirement in seismic design of Dam constructions. This article is devoted to study on Seismotectonic and seismicity and also seismic risk analysis of the Baychebaq reservoir dam. These studies involve detecting seismic sources and assessing seismicity parameters. According to the studies, Peak Ground Acceleration (PGA) is 0.1 gal. This PHA may be related to … …Current Research in Geoscience, Vol. 7, Issue 2 · 10 Nov 2017 · 7,807 accessesView PDF Cite

Research ArticleOpen accessGully Erosion Rate Assessment at the Choqazanbil Temple Using GIS MethodsHadi JarahiThe Choqazanbil temple located at 60 km of south west of shush city in the south west of Iran. This temple with 3500 years archaism is one of the oldest historical titles in Iran. The temple position is close to the Sardarabad anticline with Neogene to Quaternary deposits. Many news about damaging of ancient buildings are reported most recently. This … …Current Research in Geoscience, Vol. 7, Issue 2 · 6 Nov 2017 · 7,571 accessesView PDF Cite

Research ArticleOpen accessDelineate 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 accessProbabilistic 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. The … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 3 · 16 Jun 2016 · 8,278 accessesView PDF Cite

Research ArticleOpen accessRock Fall Hazard Zonation in Haraz HighwayHadi Jarahi, Sedigheh SeifilalehTakavar and Ebtehaj tunnels as part of Haraz highway are located in southwestern Damavand mount. Statistics show enormous financial and human damages in this route because of rockfall. Geological and topographical conditions, caused to the intensity of rockfall, because most of heights in this area covered by Damavand Trachyandesitic lava flows. In this study Rockfall Analyst (RA) software used to … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 2 · 3 May 2016 · 7,768 accessesView PDF Cite

Research ArticleOpen accessShort Period Spectral Acceleration Zonation of Tehran a Comparison between Slip and Activity Rates Data’sHadi Jarahi, Noushin Naraghiaraghi, Malihe NadalianThis study presents seismic hazard analysis and provides spectral iso acceleration maps based on slip rate (SR) and also activity rate (AR) of the faults. Nowadays modern seismic design of structures is complicated so special attention to the nature of the seismicity in active seismic zones like Tehran is required. Many studies, based on seismic hazard analysis have been done … …Current Research in Geoscience, Vol. 6, Issue 1 · 18 Feb 2016 · 8,267 accessesView PDF Cite
