What is it about?
Prediction of earthquake occurrence is a long time desire for seismologist and seismic hazard. Strong magnitude earthquake such as Mw 6.6 Chamoli event of 1999 has more prospective to imprint precursory signatures. From nearly 7 decades, the researchers are getting anomalous changes within Radon time series. in this work Helium and Radon data collected for over three years period denote precursory signatures to this earthquake event of the Himalaya.

Why is it important?
This study can lead a prospective parameter for the earthquake prediction. The anomalous changes before the occurrence of the earthquake is an additive aspect for future research. The plots of the paper can itself give a visual aspect of pre-earthquake variability to the long term background level of the data sets.
Perspectives
Citations of this earthquake already has proved the quality of this research work. For me it was a great experience to collect the data from remote locations of the Himalaya. This was initial period of my research carrier, the important results gave me a positive environment for further research work.
