Earthquake and Disaster Impact Studies Earthquake Detection and Analysis Seismology and Earthquake Studies

Abstract

In this study, the wireless communication data obtained after the earthquake are introduced to rapidly assess the earthquake disaster. Firstly, the wireless communication data including the real-time signaling data and the base station data are used to analyze the activities and the relationship of the mobile phones and the base stations. Based on the analysis results, five signaling parameters are selected and the Apriori algorithm is used to judge the damaged status of the stations. All the base stations within the affected area of the earthquake are divided into several categories according to the damage levels. Each category will produce a range of earthquake damage in the spatial domain within the affected area. Finally, when the earthquake disaster-stricken areas are located, the extent of the damage will be estimated. The Wenchuan earthquake, happened on May 12, 2008 in Sichuan Province of China reflects that the method discussed in the paper is feasible. The Wenchuan EQ also shows that the wireless communication data is very useful when we assess the damage soon after the disaster occurred, especially when there is no other way to get the field disaster information.
