Structural Knowledge Discovery Used to Analyze Earthquake Activity

Jesus A. Gonzalez, Lawrence B. Holder, and Diane J. Cook, University of Texas at Arlington, USA

The Subdue structural discovery system is being used as the Data Mining tool to study the "Orizaba Fault" located in Mexico, as part of a research project of the geologist Dr. Burke Burkart. We analyze the information of the Earthquake Database to discover if the earthquake activity in the area is related to the fault. We experimented with different samples of data mainly using two heuristics to guide Subdue through the substructure discovery process. We also added some spatio-temporal information as background knowledge. The results show how Subdue can successfully be used as a Data Mining tool in Real World Domains.
