Seismotectonics of the East Alborz and Kopeh- Dagh zones using local seismic network data

M. Kouhpeyma; M. Talebian; L. Chen; A. Ghods; M. Ghorashi

Volume 31, Issue 1 , June 2021, , Pages 199-208


  The Kopeh Dagh and Binalud-Alla Dagh mountains are important structural elements located in the northeastern boundary of Arabia-Eurasia collision zone. Due to existence of large cities with a long history of civilization, there is a relatively rich body of data on historical seismicity in this area. ...  Read More

Najmeh Etemad-Saeed; Mahdi Najafi; Navid Zeinolabedin Qavim; Ghods Abdolreza

Volume 27, Issue 108 , September 2018, , Pages 3-12


  The present study provides a detailed facies and depositional environment analyses of the Neogene sediments in the northern Dezful embayment, footwall of the Zagros Mountain Front fault. The Neogene sediments in this area, including the Mishan, Aghajari, and Bakhtyari formations, constitute the thickest ...  Read More

A ML Scale for Local Earthquakes Magnitude in the Eastern-Middle Alborz

M Nemati; A.R Ghods; M.R Ghassemi

Volume 24, Issue 95 , June 2015, , Pages 115-122


  Due to absence of an appropriate scale for estimation of ML for the earthquakes in eastern Alborz Range, we calculated 1113 synthetic Wood-Anderson peak amplitudes from waveforms of 215 earthquakes recorded by 23 stations at local hypocentral distances. The events were recorded by two local temporary ...  Read More

Determination of Ground Motion Attenuation Relationship in the Tehran Region

Kh. Motaghi; A. R. Ghods; H. R. Siahkoohi

Volume 20, Issue 79 , January 2011, , Pages 61-66


  Study of ground motion attenuation in Tehran region is a very important aspect of determining a more precise hazard map of the city. For the last 10 years, three short period seismic networks have been operating in the study region by the Institute of Geophysics, University of Tehran (IGUT).  We ...  Read More
