For the first time in India, a system to detect earthquakes
and disseminate warnings has been installed in Uttarakhand, where researchers
have predicted an earthquake of magnitude 8 or greater. The system is designed
and manufactured by Italian firm, Space Dynamics which already has installed it
in Japan, Italy and US. Features of earthquake early warning The system is
incorporated with sensors which are capable to detect P (Primary) and S
(Secondary) waves generated during an earthquake. It is capable to detect the
harmless P wave, which travels faster than the S wave for advance warning. The
system has the earliest detection among those currently in use worldwide. The
second system will be established at Pithoragarh in the Kumaon region of
Uttarakhand. According to the Bureau of Indian Standards (BIS), Uttarakhand
falls under seismic zone V i.e. High-Risk Seismic Zone. Apart from it, Jammu
and Kashmir, Himachal Pradesh, Rann of Kutch (Gujarat), Northern Bihar and
Andaman & Nicobar Islands also fall under this seismic zone.
