A Tool for Processing and Inversion of MASW Data and a Study of Inter-session Variability of MASW

Geotechnical Testing Journal
ABSTRACT Multichannel analysis of surface waves (MASW) is a noninvasive active-source technique for determination of near-surface shear wave velocity (VS) profiles. Here we introduce and describe MASWavesPy, an open-source Python package for processing and inverting MASW data, whose design follows an object-oriented paradigm.

Imaging Near‐Surface Bedrock Fracturing and Fluid Pathways Using Seismic Attenuation and Velocity From Viscoacoustic Full‐Waveform Inversion of Refraction Data

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Seismic attenuation provides sensitivity to fracture density, fluid saturation, and pore geometry that complements velocity, enabling quantitative imaging of fracture architecture and associated fluid‐pathways in near‐surface bedrock. Yet high‐resolution attenuation models remain rare in refraction studies due to amplitude‐fidelity and ...

Use of surface waves for geotechnical engineering applications in Western Sydney [PDF]

Advances in Geosciences, 2013
Current in situ methods used to geotechnically characterize the ground are predominantly based on invasive mechanical techniques (e.g. CPT, SPT, DMT).

Adaptation of Iterative Supervirtual Interferometry for Enhancing Higher Modes From Surface Waves

Geophysical Prospecting, Volume 74, Issue 6, July 2026.
ABSTRACT For geotechnical applications, surface‐wave methods are one of the most important techniques for gathering information about the strength of the near surface, but these methods are sensitive to noise. Often only the fundamental mode is considered, but higher modes can also provide more information on deeper parts of the subsurface.

Integration of the GNSS method and borehole camera to model the resulting spherical cavity generated by the main charge blast in clay

Bulletin of the Mineral Research and Exploration, 2020
A depth camera was used to record the spherical cavity which occurred during blasting in clay soil. For this purpose, the integration of the Global Navigation Satellite System (GNSS) method was applied in addition to the depth camera and the laser, to ...

Reactivation Mechanism of Dormant Earthflows: Insights From the San Benedetto Landslide (Northern Apennines, Italy)

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.
Abstract Earthflows are landslides in fine‐grained materials that alternate long dormant phases of very slow movement with short paroxysmal stages of rapid motion. These rapid phases are highly destructive, often causing severe damage to buildings and infrastructure.

Investigating of soil features and landslide risk in Western-Atakent (İstanbul) using resistivity, MASW, Microtremor and boreholes methods

Open Geosciences, 2019
In Western-Atakent (İstanbul), population density is increasing day by day and settlement areas are expanding. Soil properties and landslide conditions of these expanding regions must be absolutely examined. In the geophysics, there are many methods used

Integrated VES–ERI–MASW‐Geotechnical Investigation for Building Foundation Site Suitability at the Proposed Wachemo University Referral Hospital, Hosanna, Central Ethiopia

Engineering Reports, Volume 8, Issue 5, May 2026.
Integrated VES, ERI, and MASW surveys, constrained by boreholes, delineate a central low‐resistivity/low‐V s weak corridor and more competent volcanic strata at depth. The eastern sector offers preferable foundation conditions, while identified weak zones require ground improvement or deep foundations to mitigate differential‐settlement risk.
