What is the news?
The Council of Scientific and Industrial Research -National Geophysical Research Institute (CSIR-NGRI) has launched an ‘Environmental Seismology’ group to develop a ‘Landslide and Flood Early Warning System’ for the Himalayan region.
It is based on real-time monitoring with dense seismological networks, coupled with satellite data, numerical modelling and geomorphic analysis.
What is the purpose of this early warning system?
It would enable a crucial warning several hours prior, which will save human lives and property. Its need was necessitated following the flash floods at Chamoli district in February when a steep glacier on the Nandadevi peak in Garhwal Himalaya got detached.
It caused a major avalanche and inducing flash floods in the Rishi Ganga and Alaknanda rivers in Chamoli (Uttarakhand) . It killed several persons downstream and caused damage to two power plants.
