Seismostratigraphic Modeling Using Constrained HVSR Data

Proceedings, 2017
An application of HVSR inversion is presented in order to verify the effectiveness of this technique for purposes of reconstruction of the buried geological setting where stratigraphic constraints are available. Specifically, the reconstruction of the stratigraphy in the studied area has been obtained by a seismic-stratigraphic three-dimensional ...

The Microtremor HVSRs in the SW Korean Peninsula I: Characteristics of the HVSR Peak Frequency and Amplification

Journal of the Korean earth science society, 2010
Fifteen min-microtremor data sets were collected at 136 sites from a coastal area of Kunsan and 117 sites from an inland area of Jeonju located in SW Korea, and were analyzed for the HVSR (Horizontal to Vertical Spectral Ratio) of the sites. The microtremor spectra of the coastal area have stronger energy in the lower frequency range from 1-6 Hz than ...

Rapid Estimation of Vs30 Through Elitist Genetic Algorithm HVSR Inversion and Refraction Microtremor Data Analysis in the Greater Metro Manila Area and Leyte Province, Philippines

Applied Sciences
Vs30, the average shear wave velocity in the uppermost 30 m, is a critical parameter in seismic hazard analysis. In the Philippines, the Refraction Microtremor (ReMi) survey is the standard method for Vs30 Estimation.

Multichannel Dual-Attention Generative Adversarial Network for HVSR Fault Diagnosis Under Imbalanced Data Condition

IEEE Transactions on Instrumentation and Measurement
Fault diagnosis of high-voltage shunt reactors (HVSRs) is essential for ensuring the secure operation of power grids. Loose faults in reactors can significantly impact grid safety, necessitating prompt fault diagnosis.

Free and Improved Computer Codes For HVSR Processing and Inversions

Symposium on the Application of Geophysics to Engineering and Environmental Problems 2018, 2018
The investigation of seismic ambient noise (microtremor) in spectral ratio form, known as HVSR, is extremely popular nowadays both to investigate large areas in a reduced amount of time, and to leverage a wider choice of low cost equipment. In general, measurements at multiple locations are collected to generate multiple HVSR curves which can ...
