Understanding the mechanisms and controlling factors of erosion rates is essential in order to sufficiently comprehend bigger processes such as landscape evolution. For decades, scientists have been researching erosion rates where one of the main objectives was to find the controlling factors. A variety of parameters have been suggested ranging from climate-related, basin morphometry and the te...

We combine light detection and ranging (LiDAR) digital terrain model (DTM) data and an improved mesh implementation to investigate the effects of highresolution surface topography on seismic ground motion based upon the spectralelement method. In general, topography increases the amplitude of shaking at mountain tops and ridges, whereas valleys usually have reduced ground motion, as has been ob...

Seismic isolation is a powerful tool for mitigating seismic risk and improving structural performance. However, some parameters, such as earthquake inputs soil characteristics, influence the technology’s This research aims to investigate effects of soil–structure interaction (SSI) with regard different moderate earthquakes associated distances source site, frequency content, characteristics on ...

The goal of probabilistic seismic hazard analysis (PSHA) is to quantify the rate (or probability) of exceeding various ground-motion levels at a site (or a map of sites) given all possible earthquakes. The numerical/analytical approach to PSHA was first formalized by Cornell (1968). The most comprehensive treatment to date is the SSHAC (1997) report, which covers many important procedural issue...

The goal of this paper is to develop a new empirical relationship between observed macroseismic intensity and strong ground motion parameters such as peak acceleration (PGA) velocity (PGV) for the Vrancea subcrustal earthquakes. recent earthquakes provide valuable data examine these relationships seismogenic region. This region one most active seismic zones in Europe it well-known We correlatio...

According to the requirements of nuclear safety regulations, power plants must be equipped with seismic instrumentation systems, which are mainly used for monitoring alarm and automatic shutdown during an earthquake. Both second third generation NPPs adopt Peak Ground Acceleration (PGA). However, among acceleration characteristics, isolated prominent single high frequency peaks have no decisive...

The Alpine-Himalayan orogenic belt, the well-identified seismically active region in world, has been evidenced by occurrence of recent two devastating earthquake doublets 2015 central Nepal (MW 7.8 and MW 7.3) 2023 southeastern Turkey(MW 7.5). In this study, seismic ground motion characteristics damaging earthquakes namely doublet that occurred Himalaya Turkey eastern Mediterranean investigated...

This study presents an updated attenuation model to predict the peak ground acceleration (PGA), velocity (PGV), 5% damped pseudo-spectral (SA), and average spectral (AvgSA) at hill zone of Mexico City for interface earthquakes. The strong-motion dataset comprises 33 earthquakes recorded CU station, covering a moment magnitude (Mw) range from 6.0 8.1 source-to-site distance (Rrup) 240 490 km. Gi...

A large shaking-table test of a loess slope with geometric similarity ratio 1:25 was established as prototype model the landslide in Yongguang Village, which occurred during 2013 Minxian–Zhangxian M 6.6 earthquake. Combined finite-element–numerical-simulation software, dynamic response characteristics were compared and analyzed under action same Minxian horizontal seismic wave characteristics. ...
