Deep multiparameter analysis of the precursory lithospheric, atmospheric and ionospheric anomalies before and during the 28 March 2025 Mw7.7 Myanmar-Burma earthquake

On March 28, 2025, at 06:20:52 UTC (12:50:52 LT), a catastrophic Mw 7.7 earthquake occurred in central Myanmar-Burma, marking one of the most devastating seismic events in recent history. The earthquake occurred along the Sagaing Fault (SF), a highly active right-lateral strike-slip fault that accommodates the northward motion of the Indian Plate relative to the Sunda Plate. A multiparametric approach has been applied in order to study the preparation phase of this great earthquake, analyzing data from ground, atmosphere and satellite, with a total of eleven kinds of potential earthquake precursors. The results show a sigmoid pattern of all anomalies before and during the earthquake occurrence, typical of a critical system approaching a critical point. The sequence of the anomalies and their space and time concentration support the lithosphere-atmosphere-ionosphere coupling (LAIC) model.
