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.

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.

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).

Evaluating Seismic Ambient Noise Techniques for Imaging Lava Tubes on the Moon

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract Detecting and characterizing lava tubes is a key objective of upcoming lunar missions. While evidence for their presence exists, their precise dimensions and depths remain uncertain. This study evaluates the potential of seismic ambient noise methods, such as seismic interferometry, H/V spectral ratios, distributed acoustic sensing (DAS), and ...

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 ...

Shallow Shear‐Wave Reflection Surveys in the Wellington Central Business District

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
Seismic reflection profiling using shear waves provides constraints on the thickness of sediments beneath the Wellington Central Business District. Standard seismic methods were modified for urban environments where limited grassed areas are available and levels of cultural noise are high.

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

Geological-geotechnical investigations of the historical Diriyah urban zone in Riyadh, Saudi Arabia: an integrated approach

Frontiers in Earth Science, 2023
One hundred seventy geotechnical boreholes, two geo-seismic profiles of multichannel analyses of surface waves (MASW), and two geoelectrical cross-sections of electrical resistivity tomography (ERT) were carried out in the historical Diriyah urban zone ...

Multi‐scale geophysical mapping of the brine and bedrock surfaces along the Dolores River, Paradox Valley, Colorado, December 2023

Near Surface Geophysics, Volume 24, Issue 1, Page 36-49, February 2026.
Abstract Total dissolved solids derived from salt dome–sourced brine in the underlying alluvial aquifer substantially increase with distance in the reach of the Dolores River that passes through Paradox Valley in southwestern Colorado. The area has been the site of salinity control operations since the 1990s to reduce salt loading to the downstream ...

Open-Source MASW Inversion Tool Aimed at Shear Wave Velocity Profiling for Soil Site Explorations

Geosciences, 2020
The shear wave velocity profile is of primary interest for geological characterization of soil sites and elucidation of near-surface structures. Multichannel Analysis of Surface Waves (MASW) is a seismic exploration method for determination of near ...
