Combining GPR, Passive Seismic, and Load Testing With Computational Models in the Assessment of Historical Bridges: The Case Study of the Comboa Bridge

Structural Control and Health Monitoring, Volume 2025, Issue 1, 2025.
The preservation of historical bridges usually requires extensive structural evaluations for possible damage detection. Therefore, effective techniques are essential for diagnosis and, consequently, proper maintenance and rehabilitation actions. The combination of techniques provides complementary data that support decision making.

Seismic Microzonation and Geotechnical Modeling Studies Considering Local Site Effects for İnegöl Plain (Bursa‐Turkey)

Earth and Space Science, Volume 11, Issue 11, November 2024.
Abstract Local site effects play a vital role in determining the level of structural damage to the structures built on soil. Therefore, correctly determining the underground layer structure and its physical characteristics in the lateral and vertical directions is essential for the geotechnical model.

SPAC: An alternative method to estimate earthquake site effects in Mexico City [PDF]

Geofísica Internacional, 2003
Microtremor recordings are a very useful tool for microzonation studies because of simple data acquisition and analysis. The Spatial Autocorrelation Method (SPAC) proposed by Aki (1957), may be used to constrain the velocity structure underlying the site

Subsurface Imaging in Urban Areas With Ambient Noise Using DAS and Seismometer Data Sets: Granada, Spain

Journal of Geophysical Research: Solid Earth, Volume 129, Issue 11, November 2024.
Abstract Distributed acoustic sensing (DAS) is an innovative technology with great potential for acquiring seismic data sets in urban areas. In this work, we check the suitability of a DAS data set acquired in Granada (Spain) for retrieving subsurface reflectivity from ambient noise. The fiber‐optic is a pre‐existing underground telecommunication cable

Impact of the Offshore Seismograph Network and 3‐D Seismic Velocity Structure Model on Centroid Moment Tensor Analysis for Offshore Earthquakes: Application to the Japan Trench Subduction Zone

Journal of Geophysical Research: Solid Earth, Volume 129, Issue 11, November 2024.
Abstract Recently, a widespread and densely continuous‐recording ocean‐bottom seismograph network has been deployed in the Japan Trench subduction zone. Utilizing the offshore network data improves azimuthal station coverage for offshore earthquakes in the Japan Trench subduction zone. It has a potential to obtain centroid moment tensor (CMT) solutions

The origin of ocular microtremor in man

Experimental Brain Research, 1999
A novel technique for the study of human eye movements was used to investigate the frequency components of ocular drift and microtremor in both eyes simultaneously. The tangential components of horizontal eye accelerations were recorded in seven healthy subjects using light-weight accelerometers mounted on scleral contact lenses during smooth pursuit ...
