The Japanese government plans to revise its disaster prevention strategy to address the risk of a major earthquake in the Tokyo metropolitan area. According to sources close to the matter, new measures will be rolled out over the next 10 years, focusing on minimizing fatalities when a disaster strikes.
A key element of the strategy is expanding the use of seismic breakers — automatic gas shut-off devices — to prevent post-earthquake fires. These devices will automatically cut the gas supply upon detecting strong tremors, reducing the risk of explosions and fires, historically a major cause of casualties in large earthquakes.
Japan's current strategy projects a magnitude 7.3 earthquake could hit the Tokyo area within the next 30 years, potentially causing severe loss of life and property. The revised plan emphasizes strengthening infrastructure resilience, raising public awareness, and improving early warning systems.
Other measures under consideration include retrofitting older buildings, building additional evacuation centers, and training local rescue teams. The Japanese government is expected to announce the revised strategy later this year, following consultations with experts and local authorities.
