Detecting Seismic Anomalies from Satellite and Ground-based Network Data with Multiple Parameters

The Swarm satellite mission were launched on 22 November 2013, it is the first European Space Agency’s constellation of three satellites, dedicated to monitoring geomagnetic field changes. The three satellites have delivered more than 7 year measurements to date, which provide an unprecedented opportunity for conducting a broad range of applications at global scale, including earthquake prediction study. However, for the past years, relatively little advancement has been achieved on establishing a systematic approach for detecting anomalies from the satellite data and integration with ground-based measurements for predicting earthquakes. In Dragon 3 we developed the Wavelet Maxima-based method, Geometric Moving Average Martingale (GMAM) based on the Martingale theory, the integration of Cumulative Sum (CUSUM) and Exponentially Weighted Moving Average (EWMA) called CUSUM- EWMA, and applied these methods to analyse the Wenchuan and Lushan earthquakes.
