On the behavior of site effects in central Mexico (the Mexican volcanic belt – MVB), based on records of shallow earthquakes that occurred in the zone between 1998 and 2011 [PDF]

, 2014
The Mexican volcanic belt (MVB) is a seismogenic zone that transects the central part of Mexico with an east–west orientation. The seismic risk and hazard of this seismogenic zone has not been studied in detail due to the scarcity of instrumental data as

Progressive Layer Stripping Analysis for HVSR Interpretation

The horizontal-to-vertical spectral ratio (HVSR) technique is widely used to determine site fundamental periods from ambient noise recordings, but relating the observed peak to a specific impedance contrast within layered soils remains challenging. This paper presents an enhanced implementation of hvstrip-progressive, a Python package for forward HVSR ...

Multimethod Geophysical Imaging of Intermontane Basins: The Case Study of Cascina and Palarzano Plains (Central Apennines, Italy)

International Journal of Geophysics, Volume 2025, Issue 1, 2025.
A novel and integrated geophysical approach has been applied at Cascina and Palarzano plains (Abruzzi region, Central Apennines, Italy) to investigate their subsurface structure with particular attention to the faults bounding the basins. Both plains are characterized by the highest magnetic anomaly intensity measured over the Abruzzi region (up to 10 ...

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.

1D and 2D site amplification effects at Tarcento (Friuli, NE Italy), 30years later [PDF]

, 2018
A temporary accelerometer network has been installed in Tarcento (Friuli, NE Italy), a small town heavily hit by the 1976-1977 Friuli earthquake sequence, as a part of an ongoing research project aimed at ground motion simulation and generation of ...

Improvement of Source Spectrum Fall‐Off for Simulating Ground Motion Using Stochastic Green’s Function Method

Earth and Space Science, Volume 11, Issue 10, October 2024.
Abstract The stochastic Green's function method (SGFM), which simulates the source spectra of small earthquakes based on the ω−2 model and follows the scaling law of earthquakes to synthesize into a large earthquake, is a practical ground motion simulation method in areas lacking suitable small earthquake records.

Site classification Based on Shear Wave Velocity Inversion in The Jlantah Dam Construction Project using the HVSR (Horizontal to Vertical Spectral Ratio) Analysis Method

IOP Conference Series: Earth and Environment
This research was conducted with the aim to test whether the results of the inversion of the HVSR curve can be used as complementary data for N-SPT values in classifying areas according to site classification.

Slope failure remediation using constrained horizontal‐to‐vertical spectral ratio inversion techniques

Geophysical Prospecting, Volume 72, Issue 8, Page 3157-3167, October 2024.
Abstract Slope failure rates may be exacerbated by increased precipitation patterns associated with climate change. Such events are extremely disruptive for local communities affected. Rapid engineering remediation solutions generally require immediate site characterization, including information on depth to intact bedrock and groundwater conditions ...
