Clear‐Air Turbulence Upstream of a Hydraulic Jump Leading to a Helicopter Accident—A Large Eddy Simulation

Earth and Space Science, Volume 13, Issue 10, October 2026.
Abstract This study investigates clear‐air turbulence that triggered a helicopter accident in the lee of a mountain range near Koriyama, Japan, on 1 February 2020. Using numerical weather prediction models with horizontal resolutions of 1 km and 100 m, we examined the environmental conditions and mechanisms responsible for the turbulence.

Assessing Deep Learning Segmentation Models for Mapping Landslides From LiDAR‐Based Elevation Data

Earth and Space Science, Volume 13, Issue 10, October 2026.
Abstract Robust landslide inventories are critical for characterizing landslide hazard and helping reduce societal vulnerability. For this study, LiDAR‐derived digital elevation models (DEMs), their derivatives, and a landslide inventory were used to train different deep learning segmentation models to assess the functionality of automatic segmentation

Pre‐Eruptive Volatiles and Magma Storage Depth for the 2018 Eruption at Mount Veniaminof, Alaska

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Mount Veniaminof is a frequently active, open‐system arc volcano on the Alaska Peninsula, part of the Alaska‐Aleutian arc. Mount Veniaminof's September–December 2018 eruption began with small lava flows and culminated in a larger explosive event in November that produced a 450 km long continuous ash plume—one of the volcano's most significant ...

The Aurora Vent Field at the Transition From Magmatic Accretion to Tectonic Extension on Gakkel Ridge: Constraints From Microseismicity and Aeromagnetic Observations

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract The Aurora hydrothermal vent field (AVF) is the first confirmed active vent system on the Arctic Ocean seafloor, located at the western end of the ultraslow spreading Gakkel Ridge. It marks a distinctive endmember among ridge‐axis hydrothermal systems, where volcanic construction and ultramafic influence co‐exist.

Mapping the Western Jezero Crater Rim From Orbit: Connections to Regional Geologic Units and Context for Exploration by the Mars 2020 Perseverance Rover

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract The Mars 2020 rover is currently traversing the western rim of Jezero, a Middle to Late Noachian‐aged crater formed by an impactor that struck the northwest edge of Isidis Planitia (hereafter referred to as the Isidis basin) on Mars. Previous studies suggest that pre‐Isidis basin and Noachian outcrops are preserved throughout this region ...
