Detection of karst collapses through microtremor surface waves based on windowing cross-correlation function

Carsologica Sinica
The study area is located in the karst development area of Pingxiang in the west of Jiangxi Province, China. The landform of this area is complex, low in the northwest and high in the southeast. The fold action and gravitational sliding action led to the

Analysis of microtremor records

Bulletin of the New Zealand Society for Earthquake Engineering, 1973
A previous paper 
described two techniques developed at the University of Auckland, School
of Engineering for recording microtremors. In this paper, various possible methods of analysing such records, with emphasis on the discernment
 of frequency content, are outlined.

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.

The inversion of spectral ratio H/V in a layered system using the Diffuse Field Assumption (DFA) [PDF]

, 2016
In order to evaluate the site effects on seismic ground motion and establish preventive measures to mitigate these effects, the dynamic characterization of sites is mandatory.

Subsurface Expression of the Lambton Fault and Potential for the Basin Edge Effect in the Wellington Central Business District

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
This study focuses on the subsurface structure of the Wellington basin and an assessment of the shaking potential due to the basin edge‐effect at its western margin. Seismic reflection surveys combined with gravity modelling provide data for a structural model from which to base our shaking analysis.

Frequency and Amplification for Assessing site Effects and PVS in the Padang City Railway

JIF (Jurnal Ilmu Fisika), 2023
The train uses a special line in the form of railroad tracks that produce vibrations during movement. This study aims to determine the type of soil layer and the peak particle velocity due to the train around the Padang City train line.
