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.

Networks with time structure from time series

, 2012
We propose a method of constructing a network, in which its time structure is directly incorporated, based on a deterministic model from a time series. To construct such a network, we transform a linear model containing terms with different time delays ...

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

Inferring Cenozoic Cover Thickness and Bedrock Sedimentary Material in 3D From Geophysical Data Using Machine Learning Algorithms: A Case Study in the Lockington Region, Victoria, Australia

Earth and Space Science, Volume 13, Issue 3, March 2026.
Abstract This study presents a supervised machine learning approach to constructing a 3D geological model for the Lockington area in Victoria, Australia, by integrating borehole observations, geophysical surveys (magnetic, gravity, and radiometric), and elevation data.

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.

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 ...

Numerical and experimental analysis of the leaning Tower of Pisa under earthquake [PDF]

, 2017
Twenty years have passed from the most recent studies about the dynamic behavior of the leaning Tower of Pisa. Significant changes have occurred in the meantime, the most important ones concerning the soil-structure interaction.

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.

Effect of Age on Ocular Microtremor Activity [PDF]

The Journals of Gerontology Series A: Biological Sciences and Medical Sciences, 2001
Ocular microtremor (OMT) is a high-frequency tremor of the eyes. It is present in all individuals and is related to brainstem activity. The OMT signal appears as an irregular oscillatory movement with intermittent burst-like components. The clinical interest in OMT has centered on its use in the assessment of the comatose patient, with broad agreement ...
