Enhanced Earthquake Early Warning for Shinkansen

In earthquake-prone Japan, the operator of the Shinkansen line between Osaka and Fukuoka is upgrading its earthquake early warning system. This enhancement is expected to provide an additional 20 seconds for trains, operating at speeds up to 300km/h, to slow down and avert catastrophe during a major seismic event.

Preparing for Megathrust Earthquakes and Minimizing Casualties

Experts warn that a megaquake could strike the area at any moment, making this system upgrade crucial for minimizing loss of life. The extra 20 seconds will allow passengers to brace for impact and enable trains to reduce speed, significantly mitigating potential damage and injuries.
