IISERK Broadband Seismograph

A major component of the IISER Kolkata Seismological Observatory is the 3-Component Broadband Seismograph system, deployed as a permanent station at Mohanpur. The deployment consist of:

• CMG-3T Seismometer (Flat velocity response between 360s and 50Hz)
• CMG-DM24 Digitizer
• EAM data logger with 80 Gb removable storage and network connectivity
• Global Positioning system (GPS) for location and timing.

Himalayan Seismic Networks

A large network of broadband seismograph systems are currently operational in both Sikkim and Kashmir Himalaya with the objective of studying the 3-Dimensional Crust and Upper mantle structure and earthquake source in the Himalaya and attenuation of seismic waves.

Computational Laboratory

High end computing and seismological data archival system forms the core of the computational facility at the observatory. The laboratory doubles up as a teaching and research facility for students of the Department of Earth Sciences.

Portable Seismograph Systems

We have a pool of portable seismograph systems consiting of CMG-3ESPCDs with 2Gb internal flash memory. These equipments are currently being used for the LIGO India project for seismic characterization of probable sites.
