Introduction

Since the devastating 2011 tsunami, Japan has been piloting risk reduction solutions in areas prone to severe damage from earthquakes and tsunamis. Better communication is key to these efforts - 35% of people living in affected areas in 2011 apparently did not hear the radio announcements. Sendai City is working to solve the challenge of reliable communications by developing an emergency announcement system that uses fully automated drones. These can quickly be dispatched to tell people to evacuate when tsunami alerts are issued. This new system uses a dedicated private wireless communication network and an infrared camera mounted on a drone transmits pictures of affected areas to the city's disaster response headquarters in real-time.
