India's first earthquake early warning mobile app launched in Uttarakhand

In News 
  • The Uttarakhand government on launched an Earthquake Early Warning (EEW) Mobile App -- 'Uttarakhand Bhookamp Alert' -- developed by IIT-Roorkee.
  • It is the country's first application for notifying people about earthquake alerts. 
Details 

  • The application is available in two versions, compatible with both Android and iOS platforms.
  • The project was sponsored by Uttarakhand State Disaster Management Authority (USDMA) since the Uttarakhand region is the most seismically active and prone to earthquakes.
  • EEW is a real-time earthquake information system that can detect the onset of the earthquake and issue warnings before the significant tremors take hold of the state.
  • The physical basis for an earthquake early warning system is the speed of the seismic waves, which propagate after the release of stress from faults movement.
  • The strong ground shaking is caused by shear waves which travel at about half the speed of the primary waves and much slower than electromagnetic signals.
  • The EEW system exploits this advantage.
About the program 

  • The programme was initially launched as a pilot project only by the Union Ministry of Earth Sciences for the Garhwal region of Uttarakhand. 
  • Given its success and the need of the region, the IITR's EEW project proposal was further extended by the Uttarakhand government.
  • The application will prove useful in saving many lives. People must be made aware of this app through various awareness campaigns.
