Dynamic Probabilistic Prediction of Rockburst Using a Dual‐Modality Model With Multisource Monitoring Data

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Rockburst, due to its suddenness, randomness, and harmfulness, is one of the main factors restricting the safe construction of deep underground engineering. To achieve accurate prediction of rockburst occurrence probability, a dataset for drilling and blasting (D&B) tunnel construction was established using microseismic (MS) and geological data ...

Rapid Detection and Classification of Subway Tunnel Cavities Using Moving Train Vibration and Advanced Network Training

Structural Control and Health Monitoring, Volume 2026, Issue 1, 2026.
Detecting cavity‐induced damage in subway tunnel structures remains a significant challenge due to the difficulty of full‐time and full‐area monitoring using traditional methods. This paper proposes a rapid approach for identifying and assessing the severity of cavity damage based on vibrations from moving trains.

Effects of 1267 nm Illumination on Microcirculation Regulatory Mechanisms

Journal of Biophotonics, Volume 18, Issue 12, December 2025.
The question of activation of blood flow regulatory mechanisms during laser illumination remains open to date. This study showed the effect of laser exposure on the microcirculatory bed, which appears in the form of endothelium‐dependent vascular activity.

Comparative Study of Microtremor Analysis Methods

Pure and Applied Geophysics, 2001
During a multidisciplinary microzonation pilot project in the city of Heraklion (Crete, Greece), microtremor data were collected at the top of exploratory boreholes specifically designed for the purposes of the project, over a period of 5 days, for 4 h/day at 125 Hz (continuous recordings).

Validating alternative methods to account for shallow site effects in hybrid broadband ground‐motion simulation of small‐magnitude earthquakes in New Zealand

Earthquake Spectra, Volume 41, Issue 5, Page 3914-3948, December 2025.
Proper incorporation of shallow site effects in hybrid broadband ground‐motion simulation is essential to improving predictions at soil sites. This paper validates and compares four methods to account for these effects in the predominantly linear regime, using 1446 ground motions from 213 small‐magnitude earthquakes (3.5≤MW≤5.0) recorded at 38 sites in

Evaluating Seismic Ambient Noise Techniques for Detecting Ice‐Bearing Rocks on the Moon

Earth and Space Science, Volume 12, Issue 9, September 2025.
Abstract One of the primary objectives of upcoming lunar missions is to locate ice‐bearing rocks at the South Pole. While evidence for their presence exists, the exact distribution and quantity remain uncertain. In this study, we evaluate the potential of seismic ambient noise techniques—including seismic interferometry, H/V spectral ratios ...

A frequency‐domain beamforming procedure for extracting Rayleigh wave attenuation coefficients and small‐strain damping ratio from 2D ambient noise array measurements

Earthquake Spectra, Volume 41, Issue 2, Page 1333-1363, May 2025.
The small‐strain damping ratio plays a crucial role in assessing the response of soil deposits to earthquake‐induced ground motions and general dynamic loading. The damping ratio can theoretically be inverted for after extracting frequency‐dependent Rayleigh wave attenuation coefficients from wavefields collected during surface wave testing.

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 ...
