The Uttarakhand region is seismically active region. Large earthquakes have not occurred in this region for a long time. The return period of strong and higher magnitude earthquakes have already surpassed. So, there are likely high chances of occurrence of large earthquake in this region in the near future. The laboratory has installed ~170 sensors in the whole Uttarakhand region. They are connected through the dedicated telecommunication network. The central server is established in the laboratory. Bhukamp Disaster Early Vigilante (BhuDEV), an earthquake early warning dissemination system has been developed (here Bhukamp means earthquake).
