Ionospheric Mechanisms Leading to Plasma‐Bubble Zonal Drift Reversal and Deformation During the 12 November 2025 Geomagnetic Storm

We present a multi‐instrument analysis of the ionospheric response to the intense geomagnetic storm of 12 November 2025 over the American sector, with emphasis on the longitudinally asymmetric deformation, latitudinal expansion, and zonal drift reversal of equatorial plasma bubbles (EPBs). Our analysis integrates tot...

Key Parameters for the Ionospheric Detection of Tsunamis From the 29 July 2025 Kamchatka Event

It has been demonstrated that tsunamis generate internal gravity waves (GWs) detectable in the ionosphere within 20–60 min after their generation at the ocean surface. Despite numerous simulation and observation studies on ionospheric signatures of tsunamis, the detection of Co‐tsunamic Ionospheric Disturbances (CTID...
