In order to study the earthquake seismic behaviors of ecological bags-reinforced wall, the large-scale shaking table model tests are performed. It is shown that the frequency decreases and the damping ratio increases wit...

The western coast of South America is one of the most seismogenic zones of the world, due to the subduction of the oceanic Nazca Plate below South America. The spatial distribution of large-magnitude earthquakes or of th...

Abstract This study presents a geodetically derived seismicity-rate model for Kalimantan, Indonesia—a tectonically stable yet geologically diverse region with limited earthquake and fault data. Horizontal GNSS (Global ...

The seismic load has an adverse effect on the bearing capacity of the footings. However, few studies are performed to study its impact on the bearing capacity of slopes. In this study, a rigorous analysis in the framewor...

We studied the seismic attenuation and velocity dispersion effects produced by wave-induced fluid flow in weakly consolidated sandstones containing patchy carbon dioxide CO ð Þ2 -brine distributions. The analysis also ...

Abstract Large scale geological storage of CO2 is being deployed worldwide to reduce greenhouse gas emissions to the atmosphere. Previous modeling studies have investigated the potential for CO2 migration along faults. W...

Abstract Continuous seismic data analysis identifies signals related to physical processes within the Earth or on its surface. Characterizing seismic signals yields insights into source processes and Earth's structural f...

Abstract Accurate estimation of ground motion at the surface is fundamental to seismic hazard assessment and resilient infrastructure design. The Bangladesh National Building Code (BNBC) 2020 provides generalized seismic...

Based on theoretical analysis, the spectral element method is used to study the effect of bedrock terrain on ground motion. The achievements are as follows: (1) The intensity of bedrock ground motion is related to bedroc...

A hybrid technique, FEM-IBIEM is developed for studying the scattering of seismic waves by a 3-D complex local site. The indirect boundary integral equation method (IBIEM) adopts the dynamic Green's functions of concentr...

Abstract This study presents a comprehensive framework for selecting optimal ground motion intensity measures (IMs) and developing seismic fragility curves for horseshoe tunnels. To do so, a total of 20 candidate IMs wer...

Abstract Dehydration reactions in subducted slabs have long been correlated with embrittlement and intermediate‐depth earthquakes. However, the physical process of dehydration embrittlement remains unclear due to the c...

This paper explores the application of convolutional neural networks (CNNs) in predictive modelling for seismic events and flood risks, with a particular focus on forecasting extreme quantile events that exceed historica...

We present a comprehensive study of the pulsating primary component of the long-period binary system RY Lep. The spectral energy distribution and the absence of detectable lines indicate that the companion is likely a w...

Abstract Subducted rough topography complicates seismic and aseismic slip behavior. The 2024 M 7.1 Hyuganada earthquake occurred along the megathrust with ridge subduction. We inferred coseismic slip and afterslip using ...

Large fractures tend to dominate the hydraulic and mechanical properties of fracture networks and, consequently, of fractured rock masses. Hence, their characterization is of primary interest in a variety of applications...

This study presents an integrated geophysical approach for shallow subsurface characterization using seismic refraction and Ground Penetrating Radar (GPR) at the Florida Atlantic University Boca Preserve. A 240 m transec...

Reinforced concrete (RC) piers have been widely studied and applied in bridge construction practice. To ensure the normal operation of RC piers under corrosive environments and seismic effects, new corrosion-resistant ma...

Western China faces significant seismic risks and has a relatively weak socioeconomic foundation, making systematic evaluation of its comprehensive seismic resilience strategically vital for regional sustainable developm...

The Tirúa-Mocha Island area (38.2°-38.4° S) in southern Chile has been affected by two megaearthquakes in only 50 years: the 1960 Mw=9.5 Valdivia earthquake and 2010 Mw=8.8 Maule earthquake. We studied in the field th...

Abstract Although earthquakes are known to recur in approximately the same areas, their recurrence patterns and final sizes can vary considerably. To understand this variability, we analyzed a prominent sequence of repea...
