An integrated geophysical approach for investigating hydro-geological characteristics of a debris landslide in the Wenchuan Earthquake area [PDF]
, 2017 Debris landslides are one of the most widely distributed types of landslides in the Wenchuan earthquake area. The hydro-geological structure characteristics are the fundamental basis for stability evaluation, performing protection and administration of a

NEHRP Site Classification and Preliminary Soil Amplification Maps of Lamphun City, Northern Thailand
Open Geosciences, 2016 The primary goal of this study is to generate the NEHRP soil classification map for Lamphun City using the average shear wave velocity values (Vs(30)) derived from the multi-channel analysis of surface wave (MASW) data.

Some practical applications of shear wave velocity measurements in dense sand [PDF]
E3S Web of ConferencesShear wave velocity (Vs) profiles were obtained using two techniques at a dense sand site in Blessington near Dublin, Ireland. It was shown that both the multichannel analysis of surface waves (MASW) and seismic CPT (SCPTU) techniques provided reliable ...

Multimode Rayleigh wave profiling by hybrid surface and borehole methods [PDF]
, 2014 To improve the accuracy of shallow seismic shear wave velocity profiling, we propose a minimally invasive hybrid surface-and-borehole method that enhances the detection of higher modes of Rayleigh wave dispersion data.

Uncertainty based multi-step seismic analysis for near-surface imaging
Open Geosciences, 2019 Near-surface seismic surveys are often designed for surface wave and seismic tomographic analysis. In recent years, seismic imaging methods have been more frequently used at this scale.

Prediction and evaluation of nonlinear site response with potentially liquefiable layers in the area of Nafplion (Peloponnesus, Greece) for a repeat of historical earthquakes [PDF]
, 2010 We examine the possible non-linear behaviour of potentially liquefiable layers at selected sites located within the expansion area of the town of Nafplion, East Peloponnese, Greece. Input motion is computed for three scenario earthquakes, selected on the

Fine detection of shallow coal mined-out areas by multichannel analysis of surface waves
矿业科学学报, 2022 In order to finely detect the distribution range of shallow coal mined-out areas, a low-frequency focused factor is introduced into the phase shift method, and a low-frequency focused phase shift method is proposed, which has the advantage of extracting ...
