Spatial Resolution Requirements for FDTD Modeling of Geoelectric Fields

open access: yesJournal of Geophysical Research: Space Physics
AbstractTo ensure the robustness of both civilian and military infrastructure, it is important to protect electric power grids, smart grids, and other electrotechnologies from known and possibly as‐of‐yet unknown space weather hazards. Space weather can generate intense geoelectric fields at the surface of the Earth, as well as large voltage gradients ...

Independent component analysis of geoelectric field data in the northern Nagano, Japan

open access: yesProceedings of the Japan Academy, Series B, 2009
Simultaneous anomalous change of geoelectric field was observed on January 17, 1999 at three far-distant stations in Nagano Prefecture, Japan. Eleven days after the anomalous change, an earthquake swarm with a M4.8 main shock started at a location within the triangle formed by the three stations.
