Monitoring of seismic activity in Himalayan regions : The dense seismic network in NW Himalayan is being monitored using modern seismic equipments. Presently 38 stations are under operation in NW Himalaya out of which 12 stations are connected with VSAT for real time monitoring of seismicity at Dehradun.

Multiparametric Geophysical Observations : The first ever Indian Multi-Parametric Geophysical Observatory (MPGO) is established at Ghuttu, Central Himalaya for earthquake precursory studies in an integrated manner. The simultaneous recording of multi-disciplinary parameters is being searched for characteristic space-time variation in micro-seismicity, seismic wave velocity changes, crustal deformation, and small-scale changes in gravity, resistivity, magnetic field intensity, electromagnetic and radon gas emission as well as variations in the hydrological parameters expected during the earthquake preparatory cycles.

Seismic Hazard Assessment : Seismic hazard assessment is being carried out in major populated centers/cities using different methodology. Earthquake damage scenario in a region is determined by exploring local site conditions of the region. Microzonation studies have been carried out at Dehradun, Delhi, Chandigarh and Jammu cities.

Study of Crustal/Lithospheric structure : The Local earthquake tomography (LET), Surface wave tomography, Receiver function and Magneto-telluric (MT) techniques are being utilized for sub-surface structure investigations in the Himalaya and adjoining regions. The existing dense seismic network makes it feasible to investigate area specific crustal/lithospheric velocity structure of these regions. Ongoing different profiles of BBS and MT stations across major tectonic discontinuities of Himalaya make it feasible for understanding convergence tectonics and sub-surface structures.

Study of earthquake source processes : It is being tried to understand the earthquake source processes of Himalayan earthquakes using broad spectrum of seismic velocities recorded by local seismographs. This is carried out using different approaches (e.g. P-wave first motion method and Waveform Inversion technique). The Stress Tensor Inversion (STI) technique is also used to study the regional stress pattern.
