Assessments of Liquefaction Triggering and Manifestation at Three Case History Sites in Napier Based on 1931 Hawke's Bay, New Zealand, Earthquake

Earthquake Spectra, Volume 42, Issue 3, August 2026.
The 1931 Hawke's Bay earthquake (∼MS 7.8) stands as one of New Zealand's most devastating, causing widespread liquefaction and damage across the city of Napier. However, Napier remains underrepresented in liquefaction hazard studies as compared to other regions in the country.

Use of DMT and CPTU to assess the G 0 profile in the subsoil

, 2022
The subject of this article is the analysis of the relationship between G0/MDMT and KD, where G0 is the small strain shear modulus, while MDMT and KD are respectively the constrained modulus and the horizontal stress index determined from DMT tests. This relationship allows to determine a profile with depth of G0 from standard DMT test results, useful ...

Understanding selective triggering of landslide movement in response to rainfall, Gisborne, New Zealand

New Zealand Journal of Geology and Geophysics, Volume 68, Issue 5, Page 1064-1080, December 2025.
ABSTRACT Northeastern New Zealand has a landscape susceptible to landslides, on account of (1) its proximity to an active plate boundary, (2) steep slopes, (3) young, soft, sedimentary rocks and soils, (4) landuse changes, and (5) rainfall from ex‐tropical cyclones. The interplay of these led to widespread rainfall‐induced landsliding in the first half

Field Testing of a Smart Geomat Based on Fiber Optic Sensors and Sensor Fusion for Levee Monitoring

Journal of Flood Risk Management, Volume 18, Issue 2, June 2025.
ABSTRACT Real‐time monitoring of the functionality of river embankments, especially during flood events, is an increasingly important topic in the new scenario outlined by climate change. To address this issue, the concept of the “smart levee” has recently emerged, based on the fusion of information from different types of sensors to obtain, remotely ...

Optimal Operation of BESS for Maximum Use of Its Energy in Power System Load Frequency Control Considering Economic and Technical Objectives

IET Generation, Transmission &Distribution, Volume 19, Issue 1, January/December 2025.
The primary objective of this study is to propose a methodology for setting the frequency of an automatic generation control system when integrating battery energy storage systems (BESS) and wind turbines. The introduced approach leverages an energy management system (EMS) designed to minimize the operational costs of thermal units while optimizing the

CPTU-based permeability evaluation of clays

IOP Conference Series: Earth and Environmental Science
Abstract The piezocone penetration test (CPTU) is an efficient in-situ testing method for delineating subsurface stratigraphy and interpreting geoparameters continuously with depth. However, owing to the regional sensitivity and geological diversity, the applicability of CPTU-based geotechnical parameter evaluation methods is limited ...
