by In 2011, the 311 earthquake occurred in Japan, and I believe that many people still vividly remember the pictures of that year. After the earthquake, the Japanese government has been actively rebuilding the affected areas and strengthening policies to prevent earthquakes and tsunamis. Recently, Sendai, Japan has officially launched a drone with an automatic alarm function. When a tsunami occurs, the drone will automatically take off and broadcast an alarm to call on citizens to evacuate.
According to Kyodo News, a total of 2 UAVs in Sendai City are located in the base in Miyagi No Ward. When the National Instantaneous Alert System (J-ALERT) sends a tsunami message, the UAVs will automatically lift off and fly over the coast of Sendai City. For 15 minutes, an alarm was issued and voices such as “Tsunami is coming, everyone is ordered to evacuate”, calling on local residents to evacuate as soon as possible.
The Sendai City Government pointed out that the reason for setting up drones is that in the 311 earthquake, two government employees died while assisting citizens to evacuate, so they hoped to use drone technology instead of manual evacuation guidance.
