M Norouzi; M. Lotfi; M. H. Emami; H. Jamali; A. Abedini

Volume 27, Issue 106 , March 2018, , Pages 243-256

http://dx.doi.org/10.22071/gsj.2018.58253

Abstract
  Mesgarabad area is located in ~10 km southeast of Tehran, the Central- Alborz structural zone (CASZ) of Iran. The rock units exposed in the area consist of Eocene volcanics, volcano-sedimentary and sedimentary rocks intruded by post upper Eocene granodiorite to quartz monzo-diorite. These subvolcanic ...  Read More

Analysis and Timing Synthesize of the Probable Earthquake in the Tehran Region: A Review to Paleoseismological Studies

H Nazari

Volume 24, Issue 1393 , March 2015, , Pages 263-273

http://dx.doi.org/10.22071/gsj.2015.43424

Abstract
  Many attempts have been done to prepare active faults map of the greater Tehran region, in order to evaluate of probabilistic seismic hazard of the region. Insufficient data about the depth and nature of seismic layer, lack of enough numerical information about the crustal deformation rate, and little ...  Read More

Estimation of Shear Wave Attenuation for Bam Earthquake, Strong Motion Records, Using Singular Value Decomposition

H. Ghasemi; E. Zabihi; A. Roshandel Kahoo; M. Zare

Volume 16, Issue 63 , March 2007, , Pages 124-129

http://dx.doi.org/10.22071/gsj.2008.58519

Abstract
  Strong motion records from the 2002 Bam Earthquake are used to investigate the shape of attenuation function in several frequencies ranging between 0.8 to 18 Hz.  Amplitude spectra of the records are inverted to find source scaling factor and attenuation parameters using Singular Value Decomposition ...  Read More
