A method of evaluating reliability of earthquake precursors

HUANG Qing-Hua Computational Geodynamics Laboratory, Department of Geophysics, School of Earth and Space Sciences, Peking University, Beijing 100871, China  
One method is presented propose to evaluate reliability of earthquake precursors. The research flow that can improve the significance and reliability of earthquake precursors includes: extracting precursory information from observational data, distinguishing various artificial effects, analyzing the correlation in time and space domains between the detected precursors and the investigated earthquakes, and making stochastic test. The approach of the above evaluation method can also be applied to other non-earthquake precursors. As a case study, I investigate the seismicity changes before the M = 7 3 earthquake in the western region of Tottori prefecture, Japan on October 6, 2000, using the RTL (Region-Time-Length) algorithm. The earthquake data (1975~2000) of the Japan Meteorological Agency (JMA) are chosen for this study. A clear seismic quiescence anomaly is detected before the 2000 western Tottori prefecture earthquake. The close investigation using the above evaluation method indicates that the above quiescence anomaly before the mainshock is significant and reliable.
