Entorno Geografico, 2013 El departamento del Choco, situado en el Angulo noroccidental de Colombia, es una zona singular por su posición geográfica. Las características geológicas, tectónicas, hidrológicas y meteorológicas de esta región forman un sistema geofísico complejo, con

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.Abstract We use distributed acoustic sensing along a submarine fiber‐optic cable to provide the first high‐resolution two‐dimensional shear‐wave velocity (Vs) model of the North Anatolian Fault (NAF) in the Marmara Sea. Using 7 days of ambient noise recordings, we extract Scholte wave dispersion curves via slant‐stacking and invert for the Vs structure,

Geofísica Internacional, 1982 El análisis espectral de onda P realizado en estaciones ubicadas a distancias telesísmicas, permitió la estimación de los parámetros de la fuente del temblor (mb= 6.2) de profundidad intermedia (h = 160 km), ocurrido el 15 de octubre de 1967 con ...

Investigating the Characteristics of Microseisms Using the Australian Seismic Arrays
Journal of Geophysical Research: Solid Earth, Volume 130, Issue 6, June 2025.Abstract Earth's microseisms are continuously recorded by seismographs worldwide. Yet, studies using broadband data to analyze microseisms in Australia have been rare. Building on initial research efforts that relied on the Warramunga array in the continent's center, we expand the investigation of microseisms by utilizing seismic arrays in various ...

Detecting Millimetric Slow Slip Events Along the North Anatolian Fault With GNSS
Geophysical Research Letters, Volume 52, Issue 10, 28 May 2025.Abstract Active faults release part of the elastic strain energy stored in the crust via aseismic slip, either through slow slip events (SSEs) or steady slowly creep. However, spatial and temporal interactions between these different styles of aseismic slip have yet to be quantified especially at depth.

La reconstrucción a raíz de los sismos
Revista Mexicana de Ciencias Políticas y Sociales, 2019 El tiempo transcurrido desde los días en que tuvieron lugar los sismos de septiembre de 1985, ha venido a demostrar -una vez más— la falsedad de esa tan divulgada falacia, en el sentido de que cierto sector de los investigadores universitarios haya ...

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 5, May 2025.Abstract Opposite‐direction oceanic wave interactions at the ocean surface generate microseisms between 0.1 and ∼ ${\sim} $0.5 Hz, known as secondary microseisms (SM). SM recordings aid in imaging Earth's crust, but they also impede monitoring seismic signals due to tectonic activities.

Valley of Mexico site response from non‐reference site approach
Earthquake Spectra, Volume 41, Issue 2, Page 1029-1059, May 2025.We present a model for Valley of Mexico site response that is referenced to a 30 m time‐averaged shear wave velocity (VS30) of 760 m/s. This reference condition ensures compatibility with regional ground motion models (GMM) for Central America and Mexico (CAM), which were developed from an expanded version of the NGA‐Subduction (NGA‐Sub) database as ...

Geophysical Research Letters, Volume 52, Issue 6, 28 March 2025.Abstract Shallow creep along strike‐slip faults is essential in releasing strain during earthquake cycles. However, its origin—whether inherent or triggered by earthquakes—remains debated. Using Interferometric Synthetic Aperture Radar phase‐gradient data, we map shear‐strain rates along the East Anatolian Fault Zone (EAFZ) before and after the 2020 ...
