Exploring the Dynamics of Global Plate Motion Based on the Granger Causality Test

The geodynamic mechanism is the research focus and core issue of plate motions tectonics. Analyzing time series earthquakes may help us understand relationship between two boundaries further explore movement mechanisms. Therefore, this paper uses earthquake event data Granger causality test method to quantitatively analyze interaction energy transfer from viewpoint statistics. aims pull effect push motion provide knowledge seismic relationships, even predict earthquakes: (1) directions global field are opposite Pacific, Nazca, African, Australian, Eurasian, Philippine plates. (2) slab-pull force (not limited subduction ocean plates) provides a main driving for in Pacific plate, Nazca African Australian Eurasian sea plate. (3) optimal lag length release another view forecasting earthquakes.
