Imminent Earthquake Analysis Based on Stochastic Subspace Identification

Abstract:

A novel imminent earthquake analysis method is proposed. Firstly, BHZ data are acquired from seismic networks, then, structure parameters of part of the earth are identified based on SSI (stochastic subspace identification); finally, imminent earthquake is analyzed based on the results of system identification. It is prevented from entering earth interior or using artificial seismic explosion. Location of epicenter and process of earthquake on imminent earthquake can be analyzed based on characteristics of main vibration frequency, change trend of model shape and damping by using SSI to analyze field data on earthquake event.
