NEW DELHI: The Centre will on Wednesday install micro seismic observatories in the Joshimath area that has faced land subsidence episodes.
It will help earth researchers in observing and tape-recording any micro seismic activity for suggesting preventive steps.
Officials in the ministry of earth sciences stated seismic microzonation study for the area would produce threat durable criteria for much safer dwellings and facilities in the region.
They said Joshimath fell under the highest seismic danger zone V as it experienced constant seismogenic stresses.
Seismic energy generation due to micro-earthquakes might have compromised the strength of rocks as Joshimath lies in the earthquake rupture zone of the 1999 Chamoli earthquake.
Weather factors such as extreme rainfall and flow of water from mountains into huge cracks and fractures in the subsurface rocks result in widening of cracks and speeding up the slip in rock product, they added.Currently, India has 152 seismological centers for extensive observation facilities.
The Centre has currently prepared to install 100 more such seismological centers throughout the nation for improving the real time information monitoring and data collection in the next 5 years.
