It is said that there is greater release of Radon gas before the important earthquakes. Is this knowledge currently being used to predict earthquakes minimally?
Radon gas as a earthquake precursor has been continuously used. Even there is evidences in the reported literatures that there is radon gas anomaly preceding a large earthquake. While researchers categorize it as one of the seismic precursor, however, researchers also try to validate it by incorporating more relevant parameters so as to avoid artifacts incurred by other natural causes. To get a more insight into this, the sensors are being deployed as an array along side active faults.
Thank you.
Do you have information of this? Like an excel with data.
Radon is the gaseous radioactive element. Being a noble gas it does not form compounds with other elements and do not move freely through pores, joints and faults in the subsurface either as gas or dissolved in ground water.
It is one of the products of U 238 decay series with a half life of 3.8 days and the presences of Rn222 at the surface is often an indication of buried Uranium concentration
The Emanometer is relatively slow to use in the field . However it does use for detecting deeper deposits of uranium.
Because of high mobility of Rn, it travelled a considerable distance from the source of uranium before being detected.
The Emanometer has been used to detect Radon along the faults because faults provide channels for the movement/ transport of Rn. This technique is advantageous when there is no great difference in rock properties across the fault that could be detected by other geophysical methods.
