In this study, numerical simulations are conducted to mimic the instant and delayed seismic triggering observed after this event and evaluate resultant seismic cycle perturbations at adjacent faults and near İzmir, where amplified ground motions caused heavy damage. For this purpose, Coulomb static stress changes and seismic waveforms recorded by strong-motion stations are combined as static and dynamic triggers on a rate-and-state friction dependent quasi-dynamic spring slider model with shear-normal stress coupling.

The seismic risk of the NPP is further assessed by incorporation of the rate of frequency exceedance and conditional failure probability curves. Furthermore, this framework attempts to show the unacceptable performance of the isolated NPP in terms of the probabilistic distribution and annual probability of limit states. The comparative results for long and common ground motions are discussed to contribute to the future safety of nuclear facilities against drastic events like Tohoku.

This study aims to rigorously examine the influences of the vertically propagating recorded strong ground motions on the trapezoidal-shaped hills in different sizes and shape ratios. In order to generalize the results of the study, one-dimensional as well as two-dimensional analyses are conducted. Then, intended results are represented in dimensionless form as a result of which amplification ratio patterns are extracted and compared with each other in terms of displacement, velocity, and acceleration.

Near-fault ground motions containing strong velocity pulses are of interest in the fields of seismology and earthquake engineering. Sites located in the vicinity of seismic faults may experience ground motions with the effect of forward directivity, causing most of the seismic energy in a single pulse registered early in the velocity history.

In thisstudy, seismological aspects ofthe 2017 Sarpol-e Zahab earthquake has been investigated. The Sarpol-e Zahab earthquake, of magnitude 7.3 (Mw), occurred in southwestern Iran on November 12, 2017. Here, we investigated the properties of the strong ground motions of the earthquake using the records provided by Iranian Strong Motion Network (ISMN).

For the earthquake motion level 1, the elastic limit the value of a structure is usually adopted seismic activity. For Level 2 earthquake motion, on the other hand, the limit value that a structure does not collapse or repair through the seismic activity depends on the importance of intended structure. Level 2 earthquake motions are used for verification is based on the records of strong motion seismograms obtained from the Hyogoken Nanbu earthquake and the other, and seismic waveform types are assigned according to the ground....
