Foreshock Migration Preceding the 2025 Mw 8.8 Kamchatka Earthquake: Insights From Single‐Station Observations

Geophysical Research Letters
We investigate the spatiotemporal evolution of foreshocks preceding the 2025 Mw 8.8 Kamchatka earthquake by applying single‐station analysis to waveforms recorded at the nearest seismic station.

Aerial and Space‐Borne Seismology on Venus: Viability and Design Implications for Future Missions

Earth and Space Science, Volume 13, Issue 6, June 2026.
Abstract Venus' evolution remains a mystery because of the lack of in situ geophysical data to constrain its interior structure. Recently‐selected planetary missions VERITAS (NASA), DAVINCI+ (NASA), and EnVision (ESA) will investigate the planet's interior, surface, and atmospheric chemistry.

A Deep Learning Framework for Peak Ground Velocity Prediction Using Multi‐Station Velocity Waveforms: The Taiwan Transformer Shaking Alert Model (TT‐SAM)

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.
Abstract This study proposes a deep‐learning–based regional earthquake early warning model, the Taiwan Transformer Shaking Alert Model (TT‐SAM). The model adopts peak ground velocity (PGV) as its primary ground shaking prediction unit, aiming to better reflect actual structural damage and thereby enhance the practical utility and accuracy of the ...

Source Parameters of the 1906 Manas (Mw 7.7), 1944 Xinyuan (Mw 7.2) and 1812 Nilke Earthquakes and Seismotectonics of the Borohoro Shan, Western China

Tectonics, Volume 45, Issue 6, June 2026.
Abstract The 1906 Manas Earthquake is the largest earthquake recorded in the Borohoro Shan (BRS) since 1900. The reported magnitude ranges from 7.2 to 8.3, but uncertainties remain regarding its size, mechanism, and responsible fault. Similar confusion exists for the 1812 Nilke and 1944 Xinyuan Earthquakes, the only other Mw > 7 earthquakes in the NE ...

Characteristics of Foreshock Subsolar Compressive Structures

Journal of Geophysical Research: Space Physics, 2023
Abstract The turbulent foreshock region upstream of the quasi‐parallel bow shock is dominated by waves and reflected particles that interact with each other and create a large number of different foreshock transients. The structures with the enhanced magnetic field, Short Large Amplitude Magnetic Structures, and density spikes named ...

Seismic Precursors to the Blatten, Switzerland Landslide Revealed by Unsupervised Machine Learning

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract The transition from stable to unstable states in geological systems, such as landslides and fault zones, remains poorly understood. Seismic precursors and foreshocks related to the transition, if present, are often difficult to observe, and their interpretation remains challenging.

Nucleation and Cascade Features of Earthquake Mainshock Statistically Explored from Foreshock Seismicity

Entropy, 2019
The relation between the size of an earthquake mainshock preparation zone and the magnitude of the forthcoming mainshock is different between nucleation and domino-like cascade models.

Dynamic Coupling Between Faulting, Rifting and Magmatism During 2021‐2025 Unrest on Reykjanes Peninsula, Iceland

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Interactions among faulting, earthquakes, and eruptions are fundamental to plate tectonics and hazard forecasting yet rarely observed along mid‐ocean ridges. On Iceland's Reykjanes Peninsula, seismotectonic–volcanic unrest resumed after nearly 800‐year hiatus, providing an opportunity to observe these interactions during 2021–2025 activity. By

Nonlinear Waves in the Terrestrial Quasiparallel Foreshock [PDF]

Physical Review Letters, 2016
We study the applicability of the derivative nonlinear Schrödinger (DNLS) equation, for the evolution of high frequency nonlinear waves, observed at the foreshock region of the terrestrial quasi-parallel bow shock. The use of a pseudo-potential is elucidated and, in particular, the importance of canonical representation in the correct interpretation of
