The biggest highlight of EAS is the algorithm that estimates the magnitude of the earthquake in real time simulation, in a matter of 3 seconds, only. Roorkee, being about 120 kms away from the Himalayas, can observe an S-wave in about 40 seconds, if the epicentre of the earthquake lies in Himalayas. After estimation of intensity within 3 seconds, and an additional 10 seconds for an alert to be issued, EAS provides Roorkee with a lead time of about 25-30 seconds. Additionally, warnings shall be issued, only if the magnitude of earthquake exceeds a 6 on the richter scale. Four or more sensors should back the notification, else, no warning is issued. Within the inevitable 10 seconds required for the issuing of warning, the S-wave moves ahead by about 30 km - making this region the blindspot. However, the epicentre is usually a teeny bit into the depths of Himalayas, and, hence, the corresponding blindspot turns out to be a sparsely populated region. Still, an earthquake of magnitude more than 8 can cause some serious havoc in regions reaching upto Delhi.
In recent years, the population in northern Uttar Pradesh has increased significantly, and, more importantly, the entire region sits on soft soil, which tends to amplify wave motion rather than dampen it, hence increasing seismic risk. Fortunately, due to the recent developments in all the nearby villages, broadband network and mobile phones’ connectivity has become very routine. Thus, following the Earthquake emergency measures - post-issuing of the notification - can turn out to be a life-saving choice.
