CyberShake NZ: Probabilistic Seismic Hazard Analysis in New Zealand Using Physics‐Based Ground‐Motion Simulations

Earthquake Spectra, Volume 42, Issue 4, November 2026.
This study presents the computational components and workflow developed to conduct probabilistic seismic hazard analysis (PSHA) in New Zealand (NZ) using physics‐based ground‐motion simulations, referred to as “CyberShake NZ.” Semi‐automated procedures generate multiple realizations of kinematic rupture models, create rupture‐specific velocity models ...

Normal mode splitting function measurements of anelasticity and attenuation in the Earth's inner core [PDF]

We have used the iterative spectral fitting method to measure both the elastic and anelastic splitting functions of 20 inner core sensitive normal modes.

Moist Available Potential Energy, Multiscale Energetics and the Multiscale Dynamics Governing an Extremely Devastating Rainstorm

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 18, 28 September 2026.
Abstract An unprecedented record‐breaking extreme hourly rainfall event (201.9 mm/hr) occurred on 20 July 2021, at the Zhengzhou Station, China. In previous studies, a meso‐γ $\gamma $‐scale convective storm is found to be the direct process causing the rainfall; also found is the impact of processes on other scales (synoptic‐ and meso‐scales), in ...

Mechanical Properties and Fracture Behaviour of New Zealand Nephrite Jade (Pounamu): Implications for Fibre‐Toughening Mechanisms in Amphibole Monomineralic Rocks

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 3, September 2026.
Results of the first comprehensive quantitative analysis of the mechanical properties of New Zealand nephrite jade (pounamu), including hardness, Young's modulus, fracture toughness and notched flexural strength are reported for seven samples. These samples of exceptional quality were pre‐selected by experienced Māori carvers through a ranking process.

Anelastic approximation

, 2021
This paper reconstructs the anelastic approximation in such a manner that it can be applied to any kind of fluid. As a result, it turns out that the work done by the buoyancy force in the approximation corresponds to the conversion between kinetic and internal energy. Also, the conditions for the applicability of the approximation are clarified.

In Situ Heating STEM of the Thickness‐Dependent Evolution of Ferroelastic Domains

Small, Volume 22, Issue 50, 7 September 2026.
In‐situ heating scanning transmission electron microscopy combined with machine‐learning segmentation is used to study the thickness and temperature dependent behavior of ferroelastic domain walls in free‐standing LaAlO3 samples. The results quantify domain wall curvature and density throughout cooling, revealing a pronounced thickness‐dependent ...

Medium‐Scale Traveling Ionospheric Disturbances Induced by Secondary Gravity Waves Associated With Record‐Breaking Heavy Rainfall in August 2021 Over Kyushu, Japan

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract This study reconstructs a multistep gravity wave (GW) pathway, from the generation of primary GWs by deep convection in the troposphere to the generation of secondary GWs that drive semi‐concentric medium‐scale traveling ionospheric disturbances (MSTIDs) in the ionosphere, during the record‐breaking heavy rainfall over Kyushu, Japan, in August

A Simplified Higher Order Closure + Mass Flux Boundary‐Layer Parameterization in the Goddard Earth Observing System

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 9, September 2026.
Abstract Boundary‐layer turbulence and clouds play an essential role in regulating surface fluxes and the Earth's radiative balance, but their parameterization in global models remains a significant source of uncertainty. This paper describes a novel implementation of the Simplified Higher Order Closure (SHOC) coupled with a multi‐plume eddy ...

Investigating Layered Cratonic Lithosphere in the Fennoscandian Shield

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.
Abstract Cold, thick, and chemically depleted lithosphere with high seismic velocity and low attenuation characterizes continental cratons. However, discrepancies between xenolith‐based thermal constraints and those inferred from surface‐wave seismic models, together with the widespread observation of mid‐lithosphere discontinuities, challenge the ...

Fortnightly Earth rotation, ocean tides and mantle anelasticity

This study of the fortnightly Mf tide comprises three main topics: (1) a new determination of the fortnightly component of polar motion and length of day (LOD) from a multidecade time-series of observed space-geodetic data; (2) the use of the polar ...
