Utilization of Spatially Distributed mHVSR to Assess the Effectiveness of Ground Response Analysis

Earthquake Spectra, Volume 42, Issue 1, February 2026.
One‐dimensional ground response analyses (GRAs) can introduce model error to site response estimates when wave propagation is not dominated by vertically propagating shear waves. We investigate whether the variability of spatially distributed microtremor‐based horizontal‐to‐vertical spectral ratios (mHVSR) is related to GRA effectiveness using data ...

Investigation of Hilbert–Huang Transform and Fourier Transform for Horizontal-to-Vertical Spectral Ratio Analysis: Understanding the Shallow Structure in Mataram City, Lombok, Indonesia

Frontiers in Earth Science, 2020
Because of its robustness and practicality, the Horizontal-to-Vertical Spectral Ratio (HVSR) method has been widely used to obtain subsurface structure, mainly the sediment thickness that resides over bedrock.

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.

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
