Abstract
<p>This study presents an analysis of data from various radon anomalies that were compiled by Toutain and Baubron [1999], to investigate their relationships with the earthquake parameters of magnitude and distance from epicenter. The simple methodology applied here reveals significant and positive correlation between the duration of the radon anomalies and the ratio between the earthquake preparation radius and the distance between the sensor and the event epicenter. This shows an important relationship between seismic activity and duration of radon anomalies at a local scale. The consequences and implications of this relationship are discussed.</p>
Highlights
The study of earthquake precursors has a long history that goes back to the late 19th century [e.g., Kagan and Knopoff 1987, Geller 1991, Wyss 1991; and references therein]
According to Harrison et al [2010], the radon released in this process can ionize the lower atmosphere, to produce a considerable reduction in the atmospheric electrical field
We applied a simple statistical procedure that was recently developed by Silva et al [2012] to the radon anomalies associated with seismic activity that were compiled by Toutain and Baubron [1999]
