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 ...

The 2025 Kamchatka Earthquake and Tsunami: Cascading Impacts and Risks to Japan

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 11, Page 2837-2854, September 2026.
ABSTRACT On July 29th, 2025, a large earthquake (Mw 8.8) occurred near the Kamchatka Peninsula. This event caused a tsunami that reached Japan's Pacific coast, even though the source was far away. In this study, we analyze the characteristics of earthquakes and tsunamis and discuss how they relate to the recurrence possibility and risk in Japan.

Aftershock patterns in recent central Appennines sequences

, 2019
During the last 20 years, three seismic sequences affected the Apenninic belt (central Italy): Colfiorito (1997–1998), L'Aquila (2009), and Amatrice Visso-Norcia Campotosto (2016–2017).

Some characteristics of foreshocks and aftershocks of the 2022 ML6.8 Chihshang, Taiwan, earthquake sequence

Frontiers in Earth Science
Foreshocks and aftershocks occurred before and after the ML6.8 (Mw7.0) earthquake in eastern Taiwan on 18 September 2022. We explore the epicentral distribution and temporal variations for the mainshock, foreshocks, and aftershocks.

Surface Consistent Seismic Hazard Assessment in the Shillong Plateau, Northeast India: A Probabilistic Approach Using Multiple Source Models and a Logic Tree Framework

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 11, Page 2855-2879, September 2026.
ABSTRACT We perform probabilistic seismic hazard analysis (PSHA) in the Shillong Plateau by clubbing the up‐to‐date earthquake data and seismotectonic properties of the study area. Twenty‐one areal seismic sources are delineated based on the updated earthquake catalog, tectonic, and fault plane solutions.

Aftershock Sequence Selection Code (CHURCHILL_aftershockselect)

, 2022
This python code selects aftershock sequences for moderate-large mainshocks using three methods: our own 2D and 3D methods, and an external Nearest Neighbour Declustering (NND) method. Methods are explained in the accompanying paper by Churchill, Werner,

An exploration of the relative influence of physical models for Omori’s law

Frontiers in Earth Science
Omori’s law states that the rate of aftershocks decays as a function of inverse time. There are multiple physical explanations that we reduce into a nonlinear mixed effects relation of three terms: (1) a Rate/State expression that can account for static ...

Wavelet‐Based Hurst Exponent Estimation

WIREs Computational Statistics, Volume 18, Issue 3, September 2026.
The review explores how wavelet‐based methods for estimating the Hurst parameters have developed from their theoretical roots to real‐world applications in fields like biology, engineering, and telecommunications. The review aims to highlight key techniques, compare their strengths and limitations, and point out challenges that still need to be ...

Comparative study on dynamic response and probabilistic seismic fragility of underground caverns under near-fault and far-field mainshock–aftershock sequences

Underground Space
Actual seismic events typically exhibit mainshock–aftershock sequence characteristics, and source characteristics have a significant impact on cavern response.

Probability and Recurrence of Maximum Magnitude Based on Stochastic Modeling of Internal Fault Geometry

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract The recognition that relay zones along faults can act as barriers to earthquake propagation implies that rupture size may not be random and earthquakes are constrained by fault geometry. Resolution and observational biases can, however, complicate the integration of actual fault zone geometries into deterministic modeling strategies, thereby ...
