Detection of Different Properties of Ionospheric Perturbations in the Vicinity of the Korean Peninsula After the Hunga‐Tonga Volcanic Eruption on 15 January 2022

This study reports different properties of ionospheric perturbations detected to the west and south Korean Peninsula after Hunga-Tonga volcanic eruption on 15 January 2022. Transient wave-like total electron content (TEC) modulations intense irregular TEC are in Peninsula, respectively, about 8 hr eruption. The propagate away from epicenter with a speed 302 m/s. Their occurrence time, propagation direction velocity, alignment surface air pressure indicate generation by Lamb waves generated strong L band scintillations interpreted terms poleward extension equatorial plasma bubbles (EPBs). We demonstrate association EPBs using EPB climatology derived Swarm satellite data.
