Twenty-eight (28) seismometers will be installed for the Bullet Train project (Mumbai-Ahmedabad High-Speed Rail Corridor) to ensure the safety of passengers and critical infrastructure during earthquakes. This Early Earthquake Detection System, based on Japanese Shinkansen technology, will detect earthquake-induced tremors through waves and enable an automatic power shutdown. Emergency brakes will be activated when the power shutdown is detected and the trains running in the affected area shall stop. Out of 28 seismometers, 22 will be installed along the alignment. Eight will be in Maharashtra and 14 will be in Gujarat. Seismometers will be installed in traction substations and switching posts along the alignment.
