Fault‐Controlled Plumbing System Beneath Lipari Volcanic Island Revealed by Seismic Matrix Imaging
Abstract Lipari Island hosts an active magmatic–hydrothermal system, but its deep plumbing architecture remains poorly resolved due to strong seismic scattering. We apply passive seismic matrix imaging to public vertical‐component cross‐correlation functions from the dense 2018 Lipari nodal array, recovering relative‐reflectivity structures to ∼10 km ...

Abstract The Pamir, located at the northwestern margin of the Tibetan Plateau, is undergoing E–W extension within its interior, accommodated by micro‐block motions along major fault systems; however, the mechanisms governing this modern block kinematics remain elusive.

Source‐Unbiased Subsurface Monitoring With Seismic Noise
Abstract This study addresses a key limitation of seismic noise interferometry for subsurface monitoring: the impact of non‐stationary sources on seismic velocity change estimates. Conventional methods rely on time‐period references, which can inherit source‐related effects when source conditions vary, biasing the estimated velocity changes.

Abstract Large intraplate earthquakes are paradoxical because they occur far from active plate boundaries. Northern Hainan Island (South China) hosts the 1605 Qiongbei M7.5 earthquake within a volcanic province linked to the Hainan mantle plume. New shear‐wave velocity images reveal two shallow low‐velocity zones extending to ∼10 km depth: a stronger ...

Based on experimental results and theoretical analysis, an established rock damage accumulation model that comprehensively considers the preapplied static load, impact peak value, impact frequency, and impact times. Abstract To study the rock damage mechanism under high static loading and superimposed medium strain rate cyclic impact loading, a series ...

A machine learning framework integrating multisource seismic, social, and geographic data accurately predicts kilometer‐scale seismic intensity, enabling rapid postearthquake damage assessment during data‐scarce “black‐box” periods. ABSTRACT Accurate and rapid assessment of seismic intensity is crucial for postearthquake emergency response.

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

Multi‐Hazard Shaking‐Tsunami Fatality Risk Estimation for Coastal Communities
ABSTRACT This study develops a multi‐hazard fatality risk model for a coastal community (Tofino) on Vancouver Island, Canada, subjected to earthquake‐tsunami threats from the Cascadia subduction megathrust events. The model incorporates variable population distributions and uncertain fatality rate models, in addition to other key model components, such
