Ionospheric Response to the Seismic Wave Induced by the Kamchatka Earthquake on July 29, 2025

Alexey Oinats, Mark Cedrik, Il'ya Dyukov, Aleksey Podlesnyi et autres

The July 29, 2025 earthquake near the eastern coast of the Kamchatka Peninsula induced a high-amplitude seismic wave that propagated thousands of kilometers from the epicenter. Ground vibrations caused variations in surface air pressure with periods in the infrasonic range, which propagated …

The 12 November 2025 Ugly Duckling Geomagnetic Storm: From the Sun to the Earth

Yury Yasyukevich, Ekaterina Danilchuk, Aleksandr Beletsky, Egor Borvenko et autres

The 12 November 2025 G4 geomagnetic storm-the third most intense of solar cycle 25-was triggered by a complex shock-ICME (interplanetary coronal mass ejection) structure as a result of three ICMEs and driven shocks that arrived on 11-12 November. The main enhancement in …

Spatiotemporal Development of Cosmic Noise Absorption at Subauroral Latitudes Using Multipoint Ground‐Based Riometers

Yuto Kato, K. Shiokawa, Yoshimasa Tanaka, Mitsunori Ozaki et autres

Abstract Electron density enhancements in the ionospheric D‐region due to the precipitation of high‐energy electrons (>30 keV) have been measured as increases in cosmic radio noise absorption (CNA) using ground‐based riometers. CNA has been studied since the 1960s. However, there have been …

Longitudinal Development of Cosmic Noise Absorption Based on Multipoint Observations at Subauroral Latitudes During Storm‐Time Substorms on 25–28 August 2018

Yuto Kato, K. Shiokawa, Yoshimasa Tanaka, Mitsunori Ozaki et autres

Abstract Enhancements in electron density in the D‐region ionosphere attributed to the precipitation of high‐energy electrons, have previously been inferred from increases in cosmic radio noise absorption (CNA) using ground‐based riometers. However, there have been few studies of CNA observations at multi‐point …
