In this paper, bivariate statistical analysis modeling was applied and validated to derive a landslide susceptibility map of Peloponnese (Greece) at a regional scale. For this purpose, landslide-conditioning factors such as elevation, slope, aspect, lithology, land cover, mean annual precipitation (MAP) and peak ground acceleration (PGA), and a landslide inventory were analyzed within a GIS env...

Abstract—This study investigated the change of weir structure performances when durability of concrete, which is the main material of weir structure, decreased due to their aging by mean of seismic fragility analysis. In the analysis, it was assumed that the elastic modulus of concrete was reduced by 10% in order to account for their aged deterioration. Additionally, the analysis of seismic fra...

ground vibrations during an earthquake can severely damage structures and equipments housed in them. many factors including earthquake magnitude, distance from the fault or epicenter, duration of strong shaking, soil condition of the site, and the frequency content of the motion define the properties of ground motion and its amplification. a deep understanding of the effects of these factors on...

Abstract Research on new seismic sources and data has already performed in 2016 to 2017. Four shallow crustal fault were observed surrounding the city of Semarang, capital Central Java Province, Indonesia. The parameters related with mechanism (reverse fault) maximum magnitude prediction (6.5 Mw) for each was also released based 2017 research. Following this research, structural evaluation espe...

Abstract Macroseismic intensity provides a qualitative description of seismic damage. It can be associated with Ground Motion Parameters (GMPs), which are extracted in near real-time from instrumental recordings during an earthquake. Several formulations this empirical association exist literature for Italy, mainly focusing on the relationship between expressed Mercalli-Cancani-Sieberg (MCS) sc...

Probabilistic seismic hazard analysis, as the most prevalent approach to evaluate earthquake hazard, is commonly based on catalogs. Although previous studies show that recurrence time of large-magnitude (Mw> 7.0) events in Iran more than ~ 1000–2000 years, available instrumentally recorded earthquakes are limited less 100 years. With idea having another proxy for seismicity rates, we propose a ...

Probabilistic seismic hazard analysis (PSHA) has been recognized as a reasonable method for quantifying threats. Traditionally, this ignores the effect of focal depth, in which ground motion prediction equations (GMPEs) are applied to estimate probability distribution associated with possible levels induced by site earthquakes, but it is limited unclear geological conditions, makes difficult pr...

  Abstract : The main objective of this study is estimating the strong motion for the Bam region using the stochastically based seismological models. The two widely used synthetic techniques namely point-source and finite-fault were utilized incorporating the source-path and site parameters into simple function. The decay factor kappa was estimated based on the data obtained from recorded stron...

Abstract This paper presents calculated ground motions for Merangin Kerinci in the Provinsi of Jambi Sumatera. The were using a probabilistic seismic hazard analysis. earthquake catalogue used analysis included all recorded earthquakes up to end July 2019, trimmed magnitude completeness. Uncertainty input parameters was considered logic tree, with branches including shallow crustal faults Great...

This study provides a comparison of results from dynamic centrifuge tests and finite element analysis model to confirm the behavior representative Korean stone pagoda cultural heritage structure against earthquakes. The indirect stiffness or physical state was estimated by measuring natural frequency masonry pagoda. actual measured be 4.5 Hz. It determined have lower than other pagodas similar ...
