Post-earthquake assessment of moderately damaged reinforced concrete plastic hinges
, 2020 Modern reinforced concrete buildings are often designed to dissipate energy during strong earthquakes by permitting the controlled formation of plastic hinges. Plastic hinges require assessment of residual capacity in post-earthquake situations. However,

GLOBAL TREND OF MEGATHRUST RESEARCH IN THE LAST TEN YEARS [PDF]
Science of Tsunami Hazards, 2022 Megathrusts have been the subject of more research recently. Therefore efforts are needed to understand the patterns, novelties, research trends, and potential future research areas connected to megathrusts.

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.Abstract We propose a method to infer detailed spatiotemporal variations in interplate coupling by integrating geodetic and seismic data. It examines whether focal mechanisms of intraplate earthquakes occurring near the plate interface align with the stressing rates caused by a geodetically derived slip‐deficit rate model, evaluating deviations from a ...

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.Abstract Megathrust slip behavior in subduction zones can vary along‐strike, yet the mechanisms driving this variability remain uncertain. The Middle America trench offshore Mexico provides an ideal setting to investigate the structural controls on megathrust slip behavior.

Dual Role of a Subducted Seamount in Megathrust Rupture Initiation and Rupture Barrier
Geophysical Research LettersUsing high‐resolution 3D tomography and a relocated 2010–2022 earthquake catalog, we identify a seamount at 20–25 km depth beneath the Mompiche–Cojimíes region in the coastal forearc of Ecuador.

Characterizing the Forearc Basement and Subducting Structures of the Northern Ecuadorian Margin
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.Abstract We present 2D P‐wave velocity (Vp) models from the northern Ecuadorian subduction zone, north of the Carnegie Ridge. Data were collected during the HIPER2 3D wide‐angle seismic experiment, both onshore and offshore. Key seismic profiles were manually picked to determine P‐wave first‐arrival times, which were used for a traveltime tomographic ...

Earthquake Source Characterization Using 3D Numerical Modeling [PDF]
, 2007 To understand the physics of earthquakes, it is important to know what happens during individual events. Dissembling the information about the source process from the recorded seismograms is a difficult and non-unique process, as there are severe trade ...
