| In this study, the atmospheric, ionospheric and crustal precursors of the Mw 7.8 Ecuador megathrust earthquake of April 16, 2016 is examined using comprehensive multiparameter GNSS analysis. Seven consecutive days of 30-second interval data from IGS stations ESMR and QUI3 (25–200 km from epicenter) are processed using CSRS-PPP software. Our analysis encompasses coordinate differences, receiver clock offsets, tropospheric parameters and co-seismic characteristics with rigorous statistical validation through Z-score analysis and Mann-Whitney U hypothesis testing. Results reveal systematic precursor signals with distinct temporal progression: clock offset anomalies emerge first (April 13), followed by coordinate variations (April 14–15) and tropospheric changes (April 15–16). QUI3 station demonstrates progressive anomaly intensification with Z-scores increasing from 2.449 to 5.634 over four … |
