This study examines the three-dimensional layered air temperature variations associated with Hualian M6.9 earthquake, which occurred on 18 September 2022, using data from National Center for Environmental Prediction (NCEP) and extracting background information through tidal forces. Changes in stratification revealed that near epicenter, anomalies began 12 peaked 13 September, pronounced increases magnitude area. These followed a seismic thermal anomaly pattern, i.e., one greater amplitude wider range land surface, decreasing altitude until they dissipated, while other exhibited high atmospheric anomalies, upper warming exceeded likely due to meteorological factors. Stable weather conditions low geomagnetic Kp index Dst during research period supported reliability of these findings. The deformation field recorded by InSAR reflects crustal directly caused fault slip stress accumulation; moreover, area significantly higher coincides areas most concentrated deformation.

The preparation phase of earthquakes (EQs) has been investigated by making full use multi-parameter and multi-layer observations EQ precursors, in order to better understand the lithosphere–atmosphere–ionosphere coupling (LAIC) process. For this purpose, we chose a specific target EQ, huge Fukushima-ken-oki on 13 February 2021 (magnitude Mj = 7.3). We initially reported precursors different physical parameters not only lithosphere, but also atmosphere ionosphere (Hayakawa et al. followed Akhoondzadeh Draz al., both based satellite observations). Our first two papers dealt with seven electromagnetic three layers (with emphasis our own ground-based lower ionosphere), while second paper Swarm magnetic field, electron density, GPS TEC ionosphere, third climatological above Earth’s surface (together TEC). have extensively reviewed all these results, coordinated temporal evolutions various relevant LAIC system; sought which hypothesis is more plausible explaining Then, came conclusion that possible channels seem exist simultaneously for EQ: fast channel (nearly simultaneous responses ground slow (or diffusion-type), time delay few several days, agent effects lithosphere lowest propagate up definite delay. Finally, suggested some research directions future elucidation channels, made comments an early warning system.
