Using the geodetic and hydroacoustic measurements toinvestigate the bathymetric and morphometric parameters ofLake Hancza (Poland)

Open Geosciences, 2015
Most of the inland lakes do not have up-to-datebathymetry. However, a significant progress in surveyingtechnologies creates a possibility to quickly and accuratelydescribe the underwater environment.

High‐Resolution Imaging of a Distant M6 Intermediate‐Depth Earthquake Using Ocean‐Bottom DAS and Seismic Network

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Distributed Acoustic Sensing (DAS) provides dense, wide‐aperture observations potentially ideal for imaging earthquake rupture processes. By combining data from a ∼450 km‐long seafloor DAS array offshore Chile and a conventional seismic network, we image an Mw 6.0 intermediate‐depth earthquake ∼400 km away in Argentina, achieving km‐scale ...

Insights Into Magmatic Degassing, Hydrothermal Dynamics, and Eruption Precursors From Long Term SO2 Emission Monitoring at Whakaari/White Island, New Zealand

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Long‐term SO2 emission rate time series are critical for deciphering the subsurface processes regulating open‐vent volcanoes, yet extracting cyclical drivers from continuous degassing records remains challenging. We analyze a 14‐year (2006–2020) SO2 emission rate data set from Whakaari/White Island, New Zealand, identifying five chronological ...

Analysis of the Charge Structure and Lightning Activity During a Severe Beijing Thunderstorm via an Innovative Balloon‐Borne 3D Electric Field Observation System

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract We developed an innovative balloon‐borne observation system based on China's BeiDou sounding platform that integrates a three‐axis electric field sensor for in‐cloud measurements of thunderstorm electrification. On 13 May 2025, this system was deployed during a severe convective storm over Beijing. In combination with multisource observations,

Ecohydrologic Processes Modify Urban Rainfall Intensification in Land‐Atmosphere Simulations

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Ecohydrologic processes influence urban water and energy cycles including convective rainfall. Coupled land‐atmosphere models, however, lack fine‐scale representation of urban ecohydrology processes. This study integrates these processes into ensemble land‐atmosphere simulations to assess changes in convective rainfall in Milwaukee, Wisconsin.

Linking Interseismic Locking to Coseismic Rupture: The 2025 Mw 8.8 Kamchatka Earthquake

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract We investigate interseismic locking on the Kamchatka megathrust, source of the 2025 Mw 8.8 earthquake, using a data‐driven probabilistic framework. Horizontal GNSS velocities constrain a boundary element model on a triangulated megathrust geometry, while an algorithmic sampling strategy estimates the locking probability for fault elements ...

Interseasonal Hysteresis and Linearity Among Surface Energy Fluxes and Soil Water Content in Observations, Reanalyses, and Model Simulations

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Understanding how surface energy partitioning varies with soil water content (SWC) is crucial to land–atmosphere (LA) coupling. This study evaluates monthly variations in SWC and surface energy budget components across CONUS using in situ observations (OBS) and model‐derived products, including reanalyses (MERRA2 and ERA5) and two CESM ...
