10.2 Regional Networks
CSIR-NGRI has been operating 174 broadband seismometers and 41 strong motion accelerometers in different parts of the country in network and profile modes (Fig.12). In recent years, Uttarakhand Himalaya has been a focus of seismological studies. A setup of 76 three-component broadband stations (in network and profile modes) and 19 strong motion stations have been operating in this region since 2017 (Srinagesh et al., 2019). This network provides high-quality digital waveforms of thousands of local, regional, and teleseismic earthquakes. The data from this network have been used to pursue seismological studies, including research in environmental seismology, especially after the 2021-02-07 glacial burst and flood event in Uttarakhand.
