Abstract:Based on big data research methods, earthquake precursory observation data of many items prior to the Ludian earthquake is used to detect abnormalities. The combination of the anomaly detecting results fit well with this earthquake. Furthermore, calculation of this region shows that the results obtained from the method introduced in this paper relate well to earthquakes greater than 5.0. The method used in the paper is a trial to introduce the big data idea to the earthquake observation data application.
