Observational Seismology

Seismological Network & Instrumentation:

• Broadband Seismometers (BBS):

  Highly sensitive instruments capable of recording a wide range of seismic frequencies. Deployed for local and regional earthquake monitoring, waveform analysis, and source parameter estimation.

• Strong Motion Accelerographs (SMA):

  Designed to capture high-amplitude ground motions from local and near-field earthquakes. Crucial for ground motion characterization, response spectra generation, and structural response analysis in seismic hazard assessments.

• Compact Broadband Seismometers (BBS):

  Compact BBS for rapid deployment of seismic network in seismically active area.

  To do the site amplification studies.

• Real-Time Data Acquisition Systems:

  Enable continuous and triggered recording of seismic data with near-real-time processing and dissemination capabilities.
