Abstract

Abstract: Based on the analysis of earthquake-reflecting characteristics of hydro-radon in Huaan Tainei well to M_L>4.5 earthquakes in Fujian and M_S>7.0 earthquakes in Taiwan region since 1987, we found that anomalies to earthquakes happened in Fujian are characterized by general sudden jump and oscillation, and seismic precursors mostly occurred in about 20 days before earthquakes, while the duration of anomalies are also shorter. Anomalies to earthquakes happened in Taiwan are characterized by high-value and long duration, and seismic precursors mostly occurred 11 months before earthquakes.We can make more accurate judgments of earthquake locations in the future basd on abnormalies from hydro-Radon in Huaan Tainei well.

Key words: Earthquake-reflecting characteristics, Hydro-radon anormaly, Fujian regions, Taiwan region
