Explosive helium burst in thermal spring emanations.
An observation has been made of an explosive helium burst showing an anomalous concentration of helium of approximately 61.6 vol% compared to the approximately 1.4 vol% normally present in the thermal spring gas emanations at Bakreswar, West Bengal. This elevated level, along with deuterium approximately 1.7 vol%, has been observed for the first time in a gas chromatograph. Attempts have been made to correlate the observations, as a precursory signal, with some recent major tectonic disturbances.
