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 ...

Propagation of coupled Rayleigh-gravity waves on the ocean floor

Geofísica Internacional, 1999
El fondo del mar puede propagar ondas acopladas de gravedad, acústicas y de Rayleigh. Se presentan expresiones para la dispersión y el flujo de energía, y se demustra que las ondas se dividen en dos ramas.

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 ...

¿SISMO-RESISTENCIA O SISMO-RESILIENCIA? Visiones cruzadas desde la ciudad a las estructuras portantes

Arteoficio, 2022
En décadas recientes, el concepto de “resiliencia” ha cobrado gran relevancia a nivel global, siendo utilizado en distintos campos del conocimiento como la biología, la psicología, la ingeniería y la planificación urbana, entre otros. Si bien, su definición general es similar en cada caso, la forma de implementación puede variar según la disciplina ...

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.

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 ...
