Seismic hazard assessment of Iran
Seismic hazard assessment Iran earthquake UN/IDNDR historical seismicity
2015/9/30
The development of the new seismic hazard map of Iran is based on probabilistic seismic hazard computation using the historical earthquakes data, geology, tectonics, fault activity and seismic source ...
Paleoearthquakes and slip rates of the North Tabriz Fault,NW Iran:preliminary results
active tectonics paleoseismology Iran Tabriz earthquake
2015/9/16
The North Tabriz Fault is a major seismogenic fault in NW Iran. The last damaging earthquakes on this fault occurred in 1721, rupturing the southeastern fault segment, and in 1780, rupturing the north...
Shallow subsurface geology and Vs characteristics of sedimentary units throughout Rasht City, Iran
Shear wave velocity Vs 30 NEHRP site classification Rasht Iran
2015/8/28
The Manjil-Rudbar earthquake of June 1990 caused widespread damage to buildings in the city of Rasht located 60 km from the epicenter. Seismic surveys, including refraction P-wave, S-wave and downhole...
Seismic microzonation of Mashhad city,northeast Iran
Site effects Microtremor Nakamura method Seismic microzonation SPT N-value
2015/8/27
Mashhad city has a substantial risk of earthquakes due to the potential of the underlying soft soils to amplify ground motions. It is therefore imperative to conduct detailed seismic hazard assessment...
Short-term seismic crustal deformation of Iran
Short-term deformation Moment tensor Velocity tensor Earthquake Iran
2015/8/17
In this paper the short-term seismic deformation of Iran is determined by the earthquake moment tensor summation. The study areas include the Alborz, Kopeh-Dagh, eastern Iran, Makran and Zagros orogen...
Empirical relationships of shear wave velocity,SPT-N value and vertical effective stress for different soils in Mashhad,Iran
Shear wave velocity Vertical effective stress Standard penetration test Downhole test, Empirical relations Mashhad Iran
2015/8/14
Shear wave velocity, Vs, is one of the important input parameters in seismic response analysis of the ground. Various methods have been examined to measure the soil Vs directly. Direct measurement of ...
Relative tectonic activity classification in the Kermanshah area, western Iran
Subduction zone Arabia and Eurasia plate high zagros region structural change
2015/1/6
Due to the closing of the subduction zone and the collision of the Arabian and Eurasian plates, the High Zagros region has always been affected by a wide range of tectonic variations. In this research...
Determining precipitable water in the atmosphere of Iran based on GPS zenith tropospheric delays
Precipitable water Zenith wet delay Radiosonde profiles GPS Modeling
2015/8/18
Precipitable water (PW) is considered as one of the most important weather parameters in meteorology. Moreover, moisture affects the propagation of the Global Positioning System’s (GPS) signals. Using...
Continuous radon monitoring in the Jowshan hot spring as an earthquake precursor, SE Iran
earthquake precursor Jowshan hot spring continuous monitoring
2017/4/12
In this paper, we present the results of the first experience for spring water 222Rn concentration continuous monitoring
in Jowshan hot spring, SE Iran, from December 2007 to July 2008. This hot spri...
Three-dimensional deformation caused by the Bam, Iran, earthquake and the origin of shallow slip deficit
Three-dimensional deformation Bam, Iran, earthquake shallow sleep deficit
2014/4/9
Our understanding of the earthquake process requires detailed insights into how the tectonic stresses are accumulated and released on seismogenic faults. We derive the full vector displacement field d...
