Abstract
Anomalous changes in radon concentration of ground water have been observed prior to certain large earthquakes. Temporal variation of radon gas concentration with probability of earthquake occurring have been previously investigated. Here we proposed a flexible method based on Laser-induced plasma spectroscopy (LIPS) for earthquake prediction by real time measurement concentration of radon gas solution in the underground water. Using fundamental harmonic Q-switched Nd:YAG laser, radon concentration fluctuation in the under ground water can be analyzed via observation of radon emission at 705.5 and 745 nm.
