Central seismic laboratory of WIHG is at Dehradun where real time seismic data is collected from the remote seismic stations of NW Himalaya. The laboratory is well equipped with the computational facilities to process and interpret the seismic data in real time mode.

Seismic stations:

Presently three seismic networks are in operation in NW Himalaya

Garhwal seismic Network

Kangara-Chamba Seismic network

Kinnaur Seismic network

GPS stations
There are several permanent GPS stations in the NW Himalaya to monitor geodynamic deformations.

Earthquake risk mitigation is performed for different cities by local site conditions using two methods (a) Multi channel analysis of the shear wave (MASW) and (b) Nakamura technique. Microzonation studies have been carried out at Dehradun, Delhi, Chandigarh and Jammu cities.


The MPGO is designed to study the earthquake precursors in an integrated manner. The MPGO is equipped with Overhauser magnetometer, tri-axial fluxgate magnetometer, magnetotelluric, SG, ULF-band induction coil magnetometer, radon data-logger, water-level recorders and is backed by the dense network of broad-band seismometers (BBS) and Global Positioning System (GPS).

  Magnetotelluric (MT)

Magnetotellurics (MT) is a natural-source, electromagnetic geophysical method of imaging structures below the earth's surface. WIHG has installed three permanent equipments each at Bhatwari, Adibadri and Ghuttu in Garhwal Himalaya.


Himalaya School Earthquake Laboratory program (HIMSELP) has been carried out in 58 schools of northern India to provide awareness and training for school children.http://www.himselp.net.in/


GPS data have been collected in five campaigns (Oct. 06, July 07, Nov. 07 and May 08) at fifteen bench marks established around the Tehri Reservoir, Uttarakhand. The data has been collected alternatively pre-monsoon and post-monsoon continuously for five days at each bench mark. The processing of the data has been done also with respect to IGS sites. The computed results have been analyzed and correlated with the velocity vectors, time series at each bench mark for different campaigns.
