Geoelectric field and seismicity changes preceding the 2018 Mw6.8 earthquake and the subsequent activity in Greece

open access: yes, 2019
A strong earthquake of magnitude Mw6.8 struck Western Greece on 25 October 2018 with epicenter at 37.515N 20.564E. It was preceded by an anomalous geolectric signal that was recorded on 2 October 2018 at a measuring station 70km away from the epicenter ...

Why Do Sudden Commencements Sometimes Generate Disproportionate Geomagnetically Induced Currents?

open access: yesSpace Weather
Geomagnetically Induced Currents (GICs) in grounded, conducting infrastructure (e.g., power networks) represent an important space weather hazard. GICs are driven by the changing magnetic field at the Earth's surface.
