Early warning of an approaching earthquake allows for the following actions to occur when appropriate systems receive ShakeAlarm® data:


  • “Duck and Cover or Evacuate” message is broadcast in populated areas such as transit stations, schools, hospitals, and shopping centers
  • Trains are brought to a full stop, avoiding catastrophic derailments and associated casualties
  • Gas and electricity are shut down
  • Elevators are returned to ground level and an open door condition
  • Metered exit doors default to open and unrestricted states
  • Bay doors are opened at fire halls and ambulance stations
  • Backup power systems are activated
