Abstract We analyze Interferometric Synthetic Aperture Radar (InSAR) and Global Navigation Satellite System (GNSS) data to characterize ground deformation and dike opening associated with the May 2021 Nyiragongo eruption. Despite documented eruptions in 1977 and 2002, Nyiragongo's magmatic system and its interaction with regional rifting remain poorly ...

Ambient‐Noise Multicomponent Multimodal Dispersion Characteristics in Thick Sedimentary Basins
Abstract Ambient noise cross‐correlations enable the extraction of multimodal surface waves, yet resolving their complex dispersion characteristics is essential for robust subsurface imaging. Using dense array data from the North China Plain, we resolve multicomponent multimodal Rayleigh and Love wave dispersion with unprecedented detail.

A Seismically Active Shear Zone in the Uppermost Mantle Beneath the Canadian Rockies
Abstract Continental mantle earthquakes are uncommon but hold important clues for understanding lithospheric rheology. Few of these earthquakes (<10) have been documented in western North America, though it is likely more exist owing to difficulties in resolving focal depth for small earthquakes.

Abstract Blind faults pose significant seismic hazards because they remain hidden beneath the surface and are often unrecognized until they generate large earthquakes. High‐resolution shallow velocity models are essential for imaging these blind structures.

Abstract This study reveals different slip patterns of tsunami sources between two prehistoric giant earthquakes along the southern Kuril Trench, based on an integration of geological data and numerical simulations. The most recent giant earthquake occurred in the 17th century and its predecessor was in the 13th–14th century.

Abstract In 2022–2023, three local‐magnitude (ML) 4.8–5.6 earthquakes shook the Peace River oilsands area of Alberta, Canada. Previous studies statistically linked the seismicity to nearby disposal activities but lacked in‐depth investigation into triggering mechanisms, including subsurface fluid migration and earthquake interaction.

Stochastic Resonance Elucidates the Emergence and Periodicity Transition of Glacial Cycles
Abstract Glacial cycles emerged with a 41‐kyr period after the Pliocene and later intensified with a 100‐kyr period in the mid‐Pleistocene, which were attributed to Earth's orbital variations. However, no significant changes in the orbital forcing were found at the two transitions, and the forcing was too small to drive these cycles. Here, a stochastic

Pattern of Inner‐Core Differential Rotation From Long‐Term Earthquake Sequences and USArray Network
Abstract How the differential rotation of the Earth's inner core (IC) has changed over time provides insights into the dynamics of the Earth's interior. Analyses of repeating earthquakes (doublets) have yielded different models. Here we present an event‐based investigation using individual events from long‐term earthquake sequences, which improves ...

Channelization Versus Retardation During Trace Element Segregation in Compaction‐Driven Fluid Flow
Abstract The migration of fluids, such as aqueous fluids and melts, is often channelized and crucial for trace element transport. However, trace elements typically migrate slower than the fluid due to partitioning between solid and fluid phases, known as retardation.

Abstract The structure and properties of mature upper oceanic plates may evolve through mechanisms such as magmatism, hydrothermal circulation, and faulting. However, high‐resolution constraints, especially those involving both P‐ and S‐waves, remain scarce, limiting our ability to detect these processes and assess their impacts on crustal properties ...
