Gangtok, Dec 7:

India’s indigenous earthquake detector   sensor installed at Sikkim University with the help from Bhabha Atomic Research Center, Mumbai under experimental project. This is first of its kind in Sikkim and the device is named Smart Radon Duo. In India 52 sensors have been installed so far including Sikkim. Radon based seismic detector has been installed at the Kanchendzonga Management block of Sikkim University and is used in earthquake prediction.

 Avinash Khare, Vice Chancellor, Sikkim University said “the sensor was installed on 26th October 2021 with the help from Bhabha Atomic Research Center under experimental project”.

 Explaining the mechanism of the sensor VC Avinash Khare shared “The Smart Radon Monitor (SRM) is a technologically advanced real time, portable, radon monitor, designed for multiple applications in radon studies.  It is useful for continuous radon monitoring in air, water and soil. Since Sikkim falls under IV and V seismic Zone and risk of earthquake is there so if we are able to analyze data properly then we can avoid an earthquake disaster as it alerts in advance looking at pressure from Radon.”

 It was also informed by the VC that, in the last decade, several studies have concluded that the elevated concentrations of radon gas in soil or groundwater could be the sign of an imminent earthquake. It is believed that the radon is released from cavities and cracks as the Earth’s crust is strained prior to the sudden slip of an earthquake. Work carried out in this direction was based upon the assumption that significant changes take place in the emission of gasses such as radon and trapped in the earth’s crust before the arrival of ‘physical jolt’ of an earthquake. This change takes place because of the physical stresses which are built up within the earth’s crust to trigger an earthquake. Work so far done has indicated the existence of a relationship between earthquake producing processes and radon movement. It has been noted that variation in radon levels is related to the intensity of an approaching earthquake. 

Meanwhile, Deputy Registrar, CB Chettri informed “This is the first time such a sensor has been installed; it fully operates on a solar system with one SIM for data transfer. The sensor automatically transmits data to Bhabha Atomic Research Centre at Mumbai. Since it is recently installed and still in the experimental phase, we are just transmitting the data and in future it will help after analyzing data.
