Cascadia Slow Earthquake Behaviors Modulated by Tectonic and Environmental Forcings

open access: yesGeophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Slow earthquakes, including episodic tremor and slip (ETS), are highly sensitive to small stress perturbations, yet their links to tectonic and non‐tectonic forcings remain unclear. Previous studies suggest that annual hydrological cycle dominates the tremor seasonal behavior in northern Cascadia.

Origin of Long‐Wavelength Variations in Crustal Thickness on Rocky Planets

open access: yesGeophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Long‐wavelength crustal thickness variations are observed on telluric planets, particularly on Mars and the Moon whereas Mercury appears to lack such variations. They may stem from two early‐stage positive feedback mechanisms that can emerge in stagnant‐lid planets.

Particle Size as a Key Remaining Uncertainty in Dust Direct Radiative Effect After EMIT: An Earth System Model Study

open access: yesGeophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Mineral dust exerts a major but uncertain radiative influence on Earth's climate. Using near‐global mineralogical constraints from NASA's Earth Surface Mineral Dust Source Investigation (EMIT) mission in an Earth system model, we quantify the relative importance of iron‐oxide content and particle size for estimating the dust direct radiative ...

Rapid UAV‐ and Ground‐Based Magnetic Mapping of Subsurface Fractures During a Volcano‐Tectonic Crisis in Grindavík, Iceland

open access: yesGeophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract We applied an integrated UAV‐ and ground‐based magnetometry workflow to map shallow subsurface fractures and cavities in the town of Grindavík during the 2023–2025 volcano‐tectonic crisis. Short‐wavelength linear and semi‐circular magnetic lows delineate open or partially open fractures and localized cavities, including features with no ...

TOTALLY GEODESIC SUBMANIFOLDS OF GL-MANIFOLDS

International Journal of Geometric Methods in Modern Physics, 2012
In this paper, for a Finsler manifold (M, F) with a Finsler metric gij(x, y) we shall consider a generalized Lagrange metrics (FGL-metrics) as the form *gij(x, y) = gij(x, y) + σ(x, y)Bi(x, y)Bj(x, y) on TM. Then we shall consider a Riemannian manifold (TM, *G) in which *G is a generalized Sasakian metric of *g on [Formula: see text]. Then we restrict
