New Framework of Combining Observations with Topographic Slope to Estimate VS30 and Its Application on Building a VS30 Map for Mainland China

Bulletin of the Seismological Society of America, 2022
ABSTRACTWe propose a new framework of VS30 proxy based on Cokriging method and apply the framework to build a VS30 map for mainland China. This framework utilizes the VS30–topographic slope correlation in the cross-semivariogram to benefit VS30 estimation and has the following benefits: (1) the estimation results are consistent with the measurement ...

Geology as a proxy for Vs30-based seismic site characterization, a case study of northern Pakistan [PDF]

Arabian Journal of Geosciences, 2018
Earthquakes, with their unpredictable and devastating nature, have resulted in large damages worldwide. Seismic site characterization maps (SSCMs) are frequently and effectively used to demarcate the locations that are prone to amplified seismic response.

VS30, site amplifications and some comparisons: The Adapazari (Turkey) case

Physics and Chemistry of the Earth, Parts A/B/C, 2013
Abstract The aim of this study was to investigate the role of V S 30 in site amplifications in the Adapazari region, Turkey. To fulfil this aim, amplifications from V S 30 measurements were compared with earthquake data for different soil types in the seismic design codes. The Adapazari area was selected as the study area, and shear-wave velocity

Microzonation models for Montreal with respect to Vs30

2015
The development of seismic microzonation maps is now a prerequisite for performing advanced seismic hazards and seismic risk assessments in urban areas. Current microzonation procedures are based on classifying site response in soil categories based on VS30. Inmany practical cases, information on shear wave velocity is sparse and analystsmust resort to

Estimates of Vs30 Based on Constrained H/V Ratio Measurements Alone

2009
Most seismic codes adopt the average shear-wave velocity as a key parameter in the first 30 m of subsoil (VS30). Estimates of VS30 are therefore required for both large- and small-scale seismic microzonation. We propose a technique to measure the VS30 based on the horizontal to vertical spectral ratio (H/V) of microtremor recorded at a single station ...

DEVELOPMENT OF VS30 MAPS USING MICROTREMORS IN BHUTAN

Bhutan is a landlocked country located in the eastern Himalayas, where the Indian plate is subducting beneath the Eurasian plate, one of the most seismically active regions in the world. The country has the potential for large earthquakes in the future, but accurate evaluations of ground motions have not been conducted.
