Research Abstract

A small measurement system was developed to observe groundwater radon concentration continuously, and it qualified through observations in the Nakaizu observatory. A preliminary model to explain preseismic anomalies of groundwater radon concentration was proposed based on observation results. This model will enable us to design a new multi-parameter observation to investigate a mechanism of preseismic anomalies and will promote methodology of earthquake prediction research.
