Near surface soil characterisation by passive ambient noise HVSR method
, 2010 This paper discusses the use of the passive horizontal-to-vertical spectral ratio (HVSR) ambient noise method for near surface characterisation of the soil layers at a proposed building site. The uniqueness of the HVSR method is in having no need for any

Utilization of Spatially Distributed mHVSR to Assess the Effectiveness of Ground Response Analysis
Earthquake Spectra, Volume 42, Issue 1, February 2026.One‐dimensional ground response analyses (GRAs) can introduce model error to site response estimates when wave propagation is not dominated by vertically propagating shear waves. We investigate whether the variability of spatially distributed microtremor‐based horizontal‐to‐vertical spectral ratios (mHVSR) is related to GRA effectiveness using data ...

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 ...

Earthquake Spectra, Volume 41, Issue 5, Page 3914-3948, December 2025.Proper incorporation of shallow site effects in hybrid broadband ground‐motion simulation is essential to improving predictions at soil sites. This paper validates and compares four methods to account for these effects in the predominantly linear regime, using 1446 ground motions from 213 small‐magnitude earthquakes (3.5≤MW≤5.0) recorded at 38 sites in

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

Site characterization of Sikkim Himalaya using HVSR
SeismicaThe northeastern state of Sikkim lying in central segment of the Himalayan orogen is a seismically active region which was plagued by the recent 2011 Mw6.9 earthquake. Analysis of local earthquakes recorded at the recently deployed seismic network of 27 broadband seismic stations revealed seismogenic zone extending down to lower crustal depths with a ...
