## ANSWER

## THE MINISTER OF STATE (INDEPENDENT CHARGE) FOR MINISTRY OF SCIENCE AND TECHNOLOGY AND EARTH SCIENCES (DR. JITENDRA SINGH)

- (a) National  Center  for  Seismology  (NCS)  under  the  Ministry  of  Earth  Sciences (MoES), is a nodal agency of the Government of India, for monitoring earthquake activity in the country, maintains the National Seismological Network consisting of  152  observatories  at  present,  spread  across  the  country  for  round-the-clock monitoring  of  seismic  activity  in  and  around  the  country.    The  state/UT  wise distribution of 152 observatories is enclosed as Annexure-1.
- (b) to (c)   Yes Sir. In order to improve the real-time seismic monitoring and data collection, all  the  152  national  seismological  observatories  are  provided  with  a  dedicated VSAT/GPRS-modem connectivity to collect the ground motion data in real-time at  24x7  operational  center  located  at  New  Delhi  for  quickly  estimating  the earthquake  parameters  soon  after  the  occurrence  of  earthquake.  The  earthquake auto-location software has recently been upgraded. It is planned to upgrade and augment  the  existing  facility  at  Central  Receiving  Station  (CRS)  of  NCS  to monitor  large  number  of  seismic  stations  in  real  time  mode  at  par  the  global standard.  Augmentation  of  seismological  observatories  across  the  country  has improved the detection threshold down to earthquake magnitude 3.0.
