the nnw-trending dena fault, with 140 km length, cuts the major structures of zagros fold-thrust belt in borujen region. the fault has divided the region in two zones, in which different structural, andmorphological features as well assedimentation and seismtectonic characteristics have developed. this study presents a new interpretation for the kinematics of dena fault based on field evidence....
Quality control (QC) in medical imaging is an ongoing process and not just a series of infrequent evaluations of medical imaging equipment. The QC process involves designing and implementing a QC program, collecting and analyzing data, investigating results that are outside the acceptance levels for the QC program, and taking corrective action to bring these results back to an acceptable level....
The characteristics of near-fault ground motion are investigated considering heterogeneous slip distribution on the fault plane. Areas on the fault plane with large slip in compare with the average slip on the fault are known as asperity. The characteristics of strong ground motions in near-fault area are strongly affected by faulting parameters such as asperity location, maximum slip of asperi...
In this paper, the activity of Kushk fault has been investigated through field observations of landslides related to the activity of Kushk fault and other evidences of its activity and the location of rural settlements in the study area of Kushk fault has been analyzed. The study area is located in Qazvin province and in the Alborz structural zone and along the Kushk fault between the coordin...
considering recent developments in earthquake engineering, researchers has detected different effects of earthquakes far and near from the fault. investigations that have been done in this area show that near fault earthquakes have shorter time period comparing far fault earthquakes and in the velocity of near fault earthquakes, there are one or more impacting pulses with a big domain and perio...
In highly heterogeneous media waves do not propagate ballistically. They interact several times with the heterogeneities of the medium and enter the multiple scattering regime. In this regime, classical imaging techniques based on direct or singly scattered waves fail. This is typically the case in fault zones and volcanoes, two highly heterogeneous structures that are of great interest for man...
