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 ...

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 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...

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...

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...

"This research allow to infer that from seismic section and well data it is possible to determine velocity anomalies variations in layers with thicknesses below to the seismic resolution using neuronal networks."

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...

We have developed three methods for the automatic picking of first breaks that can be used for marine, dynamite, or vibroseis shot records: a modified Coppens´s method, an entropy-based method, and a variogram fractal-d...
