Relation between seismicity and pre-earthquake electromagnetic emissions in terms of energy, information and entropy content [PDF]

Natural Hazards and Earth System Sciences, 2012
In this paper we show, in terms of Fisher information and approximate entropy, that the two strong impulsive kHz electromagnetic (EM) bursts recorded prior to the Athens earthquake (EQ) (7 September 1999, magnitude 5.9) present compatibility with the ...

Improving Digital Mapping of Soil Organic Carbon and Total Nitrogen Through Integration of Sentinel‐1 Backscatter, InSAR Coherence, and Sentinel‐3 OLCI/SLSTR Observations

Land Degradation &Development, EarlyView.
ABSTRACT The potential of optical satellites for the spatial prediction of soil organic carbon (SOC) and total nitrogen (STN) has long been recognized. Owing to their balanced spatial–temporal resolution, multisource observational capabilities, and unprecedented availability of free data, Sentinel satellites offer unique opportunities for mapping soil ...

Radar Analysis Approach to Assess the Status of Hydromorphotectonic Changes in Central Iran(Yazd Ardakan Plain) [PDF]

مخاطرات محیط طبیعی, 2020
The phenomenon of the subsidence of the Earth is called the downward movement of the Earth's surface, which is not easily identifiable and quantifiable due to its slow evolution.

SWOT High‐Rate Raster Data Reveals Antarctic Ice Shelf Motion and Change in Response to Ocean and Ice Dynamics

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract The NASA/CNES Surface Water and Ocean Topography (SWOT) swath‐mapping radar altimetry satellite mission, launched in December 2022, provides repeat‐track coverage to about ±78.2° latitude every 21 days, sampling many of Antarctica's most dynamic ice shelves that play key roles in constraining mass loss from the grounded ice sheet ...

Rapid Morphological Changes in the Intertidal Zone of the Ganges‐Brahmaputra Delta Revealed by SWOT Altimetry Mission

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Intertidal zones of the Ganges‐Brahmaputra (GB) delta are among the most active coastal environments worldwide, and quantifying their morphological evolution remains challenging due to rapid change and scarce in situ observations. This study presents a satellite‐based direct quantification of intertidal sediment volume change in the Meghna ...

A Delayed Return Stroke Driven by Channel Charge Accumulation

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Based on combined VHF interferometer and fast/slow antenna measurements, we document an abnormal bolt‐from‐the‐blue lightning flash, which included two strokes. There are four successive attempted dart leaders following the first return stroke. The last detected downward leader stopped advancing at approximately 94 m and decayed.

All‐Sky Interferometric Meteor Radar Observations of Zonal Structure and Drifts of Low‐Latitude Ionospheric E Region Irregularities

Earth and Space Science, 2019
All‐sky interferometric meteor radar has been operated worldwide for the measurements of neutral winds in the mesopause region. In this paper, we employ an all‐sky meteor radar and an ionospheric radar, which are situated at Ledong (18.4°N,109°E) and ...

Thickness‐Dependent Plasma Activation in Binder‐Free Multilayer Ni–Co–O Anodes for Alkaline Oxygen Evolution

Advanced Energy and Sustainability Research, Volume 7, Issue 7, July 2026.
Depth‐limited nitrogen plasma activation in binder‐free multilayer Ni–Co–O anodes enables thickness‐dependent surface modification. Plasma treatment induces enrichment of Co at the surface, increases nanoscale roughness and pore density, improves wettability, and strengthens interfacial cohesion.
