Energy and polarization of the telluric field in correlation with seismic activity in Greece

Annals of Geophysics, 2001
Many attempts have been made to disclose anomalous changes of the electromagnetic field in relation with tectonic earthquakes. We tentatively develop a new approach based on the energy and polarity of the electric field, and apply this method to the ...

Analysis of factors affecting the disturbance of geoelectric field observation at Wengtian station

地震科学进展, 2022
The quality of the geoelectric field data of Wenchang Wengtian station in Hainan Province has been declining since March 2019. The quality of the geoelectric field data has declined mainly due to the low daily correlation coefficient, the reverse change ...

Estimating Geomagnetically Induced Currents in Southern Brazil Using 3‐D Earth Resistivity Model

Space Weather, 2023
Geomagnetically induced currents (GICs) result from the interaction of the time variation of ground magnetic field during a geomagnetic disturbance with the Earth's deep electrical resistivity structure.

REPRODUCING OPERATIONAL LANDSCAPES: The Rock Mining for Indonesia's New Capital City

International Journal of Urban and Regional Research, EarlyView.
Abstract Indonesia's new capital city is designed to become a green and sustainable city. In this article, we examine the (un)sustainability of the process through which the city is coming into being. Using the sociospatial theory of planetary urbanization, we trace the dialectical relationship between the new city and sites beyond it to show how ...

Benchmarking the Swedish Power Grid Against a 1-in-100-Year Geoelectric Field Scenario [PDF]

Annales Geophysicae
Sweden’s communication and power systems have been impacted by major space weather events in the past. For instance, the May 1921 storm caused a fire at the telegraph and telephone station in Karlstad, and the 2003 Halloween storm led to a blackout in ...

Electrical Resistivity Tomography for the 2D and 3D Investigation of Pingos and Permafrost Mounds in Northern Canada's Mountain and Coastland Areas

Permafrost and Periglacial Processes, Volume 37, Issue 4, Page 804-829, October/December 2026.
ABSTRACT Pingos and related permafrost mounds are widespread periglacial landforms in Arctic environments that are ice‐rich on the one hand and contain taliks on the other, making them vulnerable to climate change. So far, the interior, geophysical characteristics, and distribution of ground ice within these dome‐ or cone‐shaped features have not been ...

Forecasting GICs and Geoelectric Fields From Solar Wind Data Using LSTMs: Application in Austria

Space Weather, 2022
The forecasting of local GIC effects has largely relied on the forecasting of dB/dt as a proxy and, to date, little attention has been paid to directly forecasting the geoelectric field or GICs themselves.

Ground Penetrating Radar Observations of Subsurface Structures From the Makgadikgadi Pans (Botswana): A Terrestrial Analogue of Martian Playa Lakes

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract Playa lakes are considered promising landing sites on Mars because of their strong astrobiological potential. Therefore, sediments and buried structures in terrestrial playa lakes have become the focus of numerous analogue studies. The inclusion of ground penetrating radar (GPR) in the payloads of Martian missions has opened new avenues for ...
