Seismic hazard of Eastern Mediterranean region

In the present study, probabilistic seismic hazard assessment was conducted for the Eastern Mediterranean region based on several new results: (1) a new comprehensive earthquake catalog, (2) seismic source models developed based on new geological, seismicity and geodetic data; and (3) new ground motion prediction equations (GMPEs). As the number of available regional ground motion records is not adequate to develop successful local GMPEs, the data in hand was employed for determining the most representative GMPEs that were developed for similar tectonic environments. Based on different earthquake recurrence models, seismic source models, and GMPEs used in the analyses, sensitivity of seismic hazard results was investigated with the application of logic tree approach. Results indicate higher peak ground acceleration values for the Cyprus island than those suggested by Eurocode 8.


Seismic hazard assessment for Cyprus
Cagnan, Zehra; TANIRCAN, GÜLÜM (Springer Science and Business Media LLC, 2010-04-01)
In the present study, probabilistic seismic hazard assessment was conducted for Cyprus based on several new results: a new comprehensive earthquake catalog, seismic source models based on new research, and new attenuation relationships. Peak ground acceleration distributions obtained for a return period of 475 years for rock conditions indicate high hazard along the southern coastline of Cyprus, where the expected ground motion is between 0.3 and 0.4 g. The rest of the island is characterized by values repr...
Seismic testing of a scaled roller-compacted-concrete gravity dam
Gharibdoust, Ali; Binici, Barış; Department of Civil Engineering (2016)
Within the last half-century, seismic response analysis of concrete gravity dams has been extensively studied. Studies reveal that two types of failure modes prevail in the form of dam body cracking or base slide. The literature lacks the conditions that clearly differentiate the two failure types. In this context a state of the art single degree of freedom pseudo-dynamic testing was developed to assess the gravity dam response on smooth foundation interface. Three different hazard levels of earthquake name...

Demarcation of areal and linear seismic sources involves a certain degree of uncertainty and this should be reflected in the final seismic hazard results. The uncertainty associated with the description of the geographical coordinates of a source zone boundary is modeled by introducing the concept of 'random boundary', where the location of the boundary is assumed to exhibit a spatial bivariate Gaussian distribution. Here the mean vector denotes the best estimate of location and the variance reflects the ma...
Spatial sensitivity of seismic hazard results to background seismic activity models
Yilmaz, N.; Yücemen, Mehmet Semih (2011-08-04)
In the probabilistic seismic hazard analysis, the past earthquake records that can not be associated with any one of the specific faults are treated as background seismic activity. Contribution of background seismic activity to seismic hazard is generally calculated by using two different models, namely: background area source with uniform seismicity and spatially smoothed seismicity model. In this study, two case studies are carried out for a large (a country) and a small region (a province) in order to in...
Fault-based Probabilistic Seismic Hazard Assessment of the Makran Subduction Zone and the Chaman Transform Fault in Pakistan: Emphasis on the Effects of Source Characterization of Megathrust
Shah, S Tanvir; Özacar, Atilla Arda; Gülerce, Zeynep (2019-04-07)
Seismic source characterization (SSC) for probabilistic seismic hazard assessment (PSHA) in regions characterized by subduction megathrusts involves a considerable degree of ambiguity due to the complex nature of subducting plates and large seismogenic depths. The lack of detailed geologic, seismic, and geodetic histories increase the uncertainties involved in constraining the parameters of the SSC model. The enigma is further enhanced in the regions where thin skinned accretionary prism faults associated w...
