Early Investigation of a Landslide Sliding Surface by HVSR and VES Geophysical Techniques Combined, a Case Study in Guarumales (Ecuador)

open access: yesApplied Sciences, 2023
The access road to the powerhouse’s hydraulic system’s facilities in Guarumales (Azuay, Ecuador) presents a medium-sized landslide. Geophysical tests were conducted in the initial research stage, combining electrical and seismic methods.

Estimating site amplification variability in Yangon, Myanmar, from a dense nodal seismic array

open access: yesEarthquake Spectra, Volume 41, Issue 4, Page 3168-3189, November 2025.
We explore a novel acquisition geometry that can be used to estimate the linear component of site amplification using a dense nodal seismic network installed in Yangon, Myanmar’s largest city. The city is surrounded by several seismically active faults, including the Sagaing Fault, which is capable of generating Mw > 7.0 earthquakes.

Preliminary analysis of amplified ground motion in Bangkok basin using HVSR curves from recent moderate to large earthquakes

open access: yesGeoenvironmental Disasters, 2023
Background The Bangkok Basin has been known from non-instrumental observations of the local population to be subject to ground motion amplification due to the deep alluvial sediments and basin geometry.

Modelling the Importance of Ground and Strong‐Motion Variables on the Damage Status in the 2023 Kahramanmaraş Earthquakes Using Supervised Machine Learning

open access: yesGeoscience Data Journal, Volume 12, Issue 4, October 2025.
KNN achieved the highest performance (0.989) using the full dataset and 0.988 with ground‐based parameters. EBd and f0 were key contributors to damage, while PGA dominated strong‐motion models. Specificity consistently outperformed sensitivity in earthquake‐parameter models.

Seismic Hazard and Microzonation Study of Tanjung Region, North Lombok (Indonesia) using Microtremor Measurement

open access: yesJurnal Pendidikan Fisika Indonesia, 2018
Tanjung Region is one of the severely damaged areas by the Lombok earthquake on June 22, 2013. Therefore, to anticipate the similar events, it is necessary to perform microzonation in this region. Objective of this study is to map the distribution of the

Application of passive seismic to the detection of buried hollows [PDF]

open access: yes, 2015
Pilot studies involving the use of passive seismic techniques in a range of geological settings and applications, e.g., mapping bedrock, studies of soil erosion and Quaternary mapping have shown that it is a versatile, non-invasive and economic ...

Subtle relict channels associated with large dolines in an area formerly beneath the Laurentide Ice Sheet, northern Ohio, USA

open access: yesBoreas, Volume 54, Issue 4, Page 567-589, October 2025.
Low‐relief dry channels appear out of place across a glaciated karst landscape in northern Ohio. Channels are only a few metres deep cut into limestone and draped with a veneer of till. Several hypotheses are proposed for explaining the channels. Low‐relief dry channels are observed across the Bellevue‐Castalia Karst Plain of north‐central Ohio, USA ...

Combining 3‐D Deep Electrical Resistivity Tomography With Magnetic Surveys to Investigate Complex Tectonic Basins: A Case Study From the Central Apennines Seismic Belt (Italy)

open access: yesTectonics, Volume 44, Issue 9, September 2025.
Abstract We use an innovative geophysical approach to reconstruct the deep structure of Campo Felice, an important extensional basin in the central Apennines (Italy) where active crustal extension is accommodated by normal faults capable of generating earthquakes of magnitude MW 6+.
