A Novel Method for Constructing Main-Aftershock Sequences and Its Application in the Global Damage Accumulation Effects Analysis of Gravity Dams

Shock and Vibration, 2021
The traditional linear elastic and Drucker–Prager (DP) models cannot truly reflect the strong nonlinear characteristics of the concrete and rock foundation of the dam under earthquake.

Time‐Variant Seismic Fragility of Reinforced Concrete Bridge Piers Considering Degradation Phenomena

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 15, Page 3796-3817, December 2026.
ABSTRACT Aging and environmental exposure progressively deteriorate the physical and mechanical properties of construction materials, thereby affecting the safety and functionality of existing infrastructure. Corrosion of steel rebars in reinforced concrete structures is widely acknowledged as the most common and detrimental degradation phenomenon, as ...

Estimating Secondary Earthquake Aftershocks from Tsunamis

Geosciences
Nonlinear solitary waves influence the Earth’s crust because wave pressure on the ocean bottom contains non-hydrostatic components. Our physical-mathematical model allows us to calculate the surplus super-hydrostatic pressure on the Earth’s crust.

Feasibility of a National Earthquake Early Warning System for New Zealand: The Propagation of Local Undamped Motion Algorithm Evaluated on a Physics‐Based Synthetic Earthquake Catalogue

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 4, December 2026.
Earthquake early warning (EEW) can reduce injuries and damage by issuing alerts before incoming shaking. We evaluate the Propagation of Local Undamped Motion (PLUM) algorithm as a candidate for a national EEW system for Aotearoa New Zealand (NZ). We develop and demonstrate a novel methodology for evaluating EEW performance under a wide range of future ...

I stumbled when I saw: Fieldwork, fallibility, and the politics of being wrong

Anthropology and Humanism, Volume 51, Issue 2, December 2026.
Abstract What does it mean for an anthropologist to be wrong? This essay takes the question seriously in two registers at once: the everyday mistakes of fieldwork, from mistranslating a greeting to misreading a shaved head as a sign of mourning, and the deeper entitlement through which our discipline claimed authority over other people's languages and ...

Largest Aftershock Nucleation Driven by Afterslip During the 2014 Iquique Sequence

, 2023
Various earthquake models predict that aseismic slip modulates the seismic rupture process but actual observations of such seismic‐aseismic interaction are scarce.

Three‐Dimensional Resistivity Imaging Constrains Crustal Heterogeneity Beneath the 2010 Yushu Ms 7.1 Earthquake Rupture

Geophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract The 2010 Yushu (eastern Tibetan Plateau) Ms 7.1 strike‐slip earthquake ruptured unilaterally toward the southeast but left a hypocentral segment without mapped surface rupture, followed by a two‐stage reorganization of aftershocks. We present a 3‐D electrical resistivity model from 70 quality‐controlled magnetotelluric sites acquired shortly ...

High Resolution Focal Mechanisms and Stress Field Orientation in Southern Italy From Short‐Term Dense Arrays

Geophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract Understanding fault geometry and mechanics is key to interpreting the seismotectonic setting of a region. We analyze data from a 1‐year dense seismic array deployment in Southern Italy to infer focal mechanisms and stress field from low‐magnitude earthquakes using machine‐learning techniques.

DEFORMATION INTERACTION OF STRONG EARTHQUAKES OF 2010–2016 IN THE ZONE OF INFLUENCE OF THE HIKURANGA SUPERPLUME (NEW ZEALAND) ACCORDING TO GPS OBSERVATIONS

Геодинамика и тектонофизика
Between 2010 and 2016, a series of 11 strong M>6 earthquakes occurred in New Zealand. In the area covering the epicentral zones of these seismic events, the spatiotemporal characteristics of movements and deformations of the Earth’s crust were ...
