Abstract The joint probability distribution of different intensity measures at sites in one earthquake is needed to define the stochastic process regulating exceedance (in time) ensemble sites, which turn a funding element so‐called multi‐site probabilistic seismic hazard analysis (MSPSHA). simplest model for event requires mean vector and covariance matrix all conditional magnitude location ea...

Performance based seismic design (PBSD) is a cogent design approach that allows engineers to design structures with a predictable seismic performance for a specified level of hazard. In contrast to the conventional limit state or strength and serviceability based design in which a structure is designed to withstand severe load combinations and be functional under normal load conditions, PBSD go...

Abstract The design of critical facilities needs a targeted computation the expected ground motion levels. Trans Adriatic Pipeline (TAP) is pipeline that transports natural gas from Greek-Turkish border, through Greece and Albania, to Italy. We present here probabilistic seismic hazard analysis (PSHA) we performed for this facility, deaggregation results, aiming identify dominant sources select...

Recently developed numerical simulation technique can simulate the coupled seismic and electromagnetic signals for a double couple point source or a finite fault planar source. Besides the source effect, the simulation results showed that both medium structure and medium property could affect the coupled seismic and electromagnetic signals. The waveform of coupled signals for a layered structur...

The SiSeRHMap (simulator for mapped seismic response using a hybrid model) is a computerized methodology capable of elaborating prediction maps of seismic response in terms of acceleration spectra. It was realized on the basis of a hybrid model which combines different approaches and models in a new and non-conventional way. These approaches and models are organized in a code architecture compo...

Four different earthquake ground motion levels with probabilities of exceedance were expressed the current seismic design code. In this study, earthquake-structural parameters obtained by taking into account four for provinces hazards. Structural analyses carried out using each province. structural analysis, a sample reinforced-concrete structure same characteristics was selected. The results b...

Continental intraplate seismicity seems often episodic, clustered, and migrating. The observed seismicity shows both spatial clustering in seismic zones and scattering across large plate interiors, temporal clustering followed by long periods of quiescence, and migration of seismicity from one seismic zone to another. Here, we explore the complex spatiotemporal patterns of intraplate seismicity...

The Iranian plateau formed by the active tectonics of the Alpine-Himalayan belt, is situated between the Eurasian and Arabian plates. The plateau is considered as one of the most seismically active regions in the world and is faced with different earthquakes each year. Active tectonic conditions, different faults and seismic sources and a large population in earthquake-prone areas mak...

The project entitled Global Ground Motion Prediction Equations is funded by the Global Earthquake Model (GEM) Foundation and has the objective of recommending a harmonized suite of ground motion prediction equations (GMPEs) that can be used at the global and regional scales for seismic hazard analysis and loss estimation studies. As part of this project, Task 1a experts were commissioned to mak...

PURPOSE The aim of this study was to show the usefulness of three methods for measuring IOP: Goldmann applanation tonometry, rebound tonometry, and Ultra-High-Speed Scheimpflug technology. METHODS The examined group consisted of 96 patients (192 eyes), including 63 women and 33 men with a mean age of 59.3 ± 19.9 years. Together, 152 healthy eyes and 40 eyes with different pathologies were exa...
