 Abstract: We present a multi-parameter study of transient phenomena observed in the Earth's atmosphere-ionosphere environment plausibly associated with the latest major seismic activities in 2021. The year 2021 was the most active period for global seismicity since 2007, with 19 major earthquakes (M7+), three of which were over M8.0. The M 7.2 in Haiti was the deadliest for 2021, with 2,476 fatalities (USGS).We monitored critical processes in the atmosphere /ionosphere that modify the Earth's plasma environment system under various geophysical conditions, including earthquakes. We collected operational data from several instruments:1. Electric field and plasma observations from the China/Italy Seismo-Electromagnetic Satellite (CSES1); 2/ Outgoing long-wavelength radiation (OLR) obtained from NPOESS); 2/ Atmospheric chemical potential (ACP) obtained from NASA assimilation models; and 3/ Electron density variations in the ionosphere via GPS Total Electron Content (GPS/TEC).We observed a synergetic abnormal response of satellite OLR data, plasma data from CSES, and GPS/TEC and ACP starting two weeks before the M 8.1 - South Sandwich; M 8.2 – Alaska, US; M 8.1 - Kermadec Islands, NZ, and M 7.2 - Nippes, Haiti earthquake. Our integrating data search reveals different abnormal patterns inside the Dobrovolsky-Bowman estimating earthquake preparation zone. We show that by combining the near-space and ground data accordingly to the physical concept of the Lithosphere-Atmosphere-Ionosphere Coupling (LAIC), we could identify, on a regional basis, abnormal patterns of pre-earthquake-related features in the atmosphere-ionosphere environment. The implications of studying major earthquake events are discussed.
