How The Prediction Of Earth Quake Can Be Done With Radon Gas ( A Zero Group Element)?
This Question belonges to chemistry. Radon gas belonges to group no (8) this group also called noble Or zero group Bcoz of its Oxiadation state that is Zero.

It has been reported by Rikitake, 1976 (Internet) that the ratio of the P wave velocity to the S wave velocity decreases prior to a large earthquake by approximately 10% and returns to normal immediately before and following the earthquake. The diffusion of gases into the crack and subsequent contact of the crack surfaces to ground water could account for the presence of radon gas in deep wells reported prior to an earthquake. If hydrocarbons are present in the chamber created by the crack, the high pressures generated during a seismic event could possibly force these hot gases to the surface where ignition would occur. This could account for the “earthquake lights” reported by many observers during an earthquake. The presence of hydrocarbons in gaseous form under such high pressures and temperatures could produce a higher chain molecule through polymerization which would account for the presence of petroleum bearing rocks in regions of high fault activity. These cracks could also account for the decrease in electrical resistance of the earth prior to a large earthquake.
