Isotropic and Anisotropic P Wave Velocity Structures of the Crust and Uppermost Mantle Beneath Turkey

Journal of Geophysical Research: Solid Earth, Volume 125, Issue 12, December 2020., 2020
Abstract Compressional and extensional tectonics following northward plate convergences since the Miocene have formed the major surface features in Turkey, such as faulting and orogeny. Despite increasing efforts in last few decades aiming to elucidate the current architecture of the crust and mantle beneath Turkey, several issues regarding the depth ...

Bayesian Inversion of Wrapped Satellite Interferometric Phase to Estimate Fault and Volcano Surface Ground Deformation Models

Journal of Geophysical Research: Solid Earth, Volume 125, Issue 5, May 2020., 2020
Abstract Bayesian inference and an improved downsampling method is used to determine earthquake and volcano source parameters using a popular geodetic observation method, satellite radar interferometry. The main novelty of the proposed approach is that the interferometric wrapped phase can be directly inverted, circumventing the ill‐posed phase ...

Structural Control on Megathrust Rupture and Slip Behavior: Insights From the 2016 Mw 7.8 Pedernales Ecuador Earthquake

Journal of Geophysical Research: Solid Earth, Volume 125, Issue 2, February 2020., 2020
Abstract The heterogeneous seafloor topography of the Nazca Plate as it enters the Ecuador subduction zone provides an opportunity to document the influence of seafloor roughness on slip behavior and megathrust rupture. The 2016 Mw 7.8 Pedernales Ecuador earthquake was followed by a rich and active postseismic sequence.

Propuesta de Aislamiento para Mampostería de Bloques de Concreto en Pórticos de Hormigón Armado

Ingenio, 2023
Ecuador, se ubica en el Cinturón de Fuego del Pacífico donde ocurre el 90 % de la actividad sísmica del planeta. Por esta razón las edificaciones aporticadas que se construyen localmente son muy vulnerables a sufrir daño en sus elementos. A esto se suma

Design of a Tuned Mass Damper Inerter (TMDI) Based on an Exhaustive Search Optimization for Structural Control of Buildings under Seismic Excitations

Shock and Vibration, Volume 2020, Issue 1, 2020., 2020
A tuned mass damper inerter (TMDI) is a new class of passive control device based on the inclusion of an inerter mechanism into a conventional tuned mass damper (TMD). The inerter device provides inertial resisting forces to the controlled system, through relatively small masses, converting it in a mechanism with the potential to enhance the ...

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 ...

Structure Heterogeneity Around the Western End of the 1999 Izmit Earthquake Rupture Revealed by Distributed Acoustic Sensing

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,
