For early earthquake warning: 28 seismometers to be installed along bullet train corridor

“After a detailed survey and soil suitability study through a micro-tremor test, the sites were selected. Out of the 28 seismometers, 22 will be installed along the alignment. Eight will be in Maharashtra—Mumbai, Thane, Virar, and Boisar — and fourteen will be in Gujarat — Vapi, Bilimora, Surat, Bharuch, Vadodara, Anand, Mahemdabad, and Ahmedabad. Seismometers will be installed in Traction Substations and Switching Posts along the alignment. The remaining six seismometers (termed as inland seismometers) will be installed in earthquake-prone areas — Khed, Ratnagiri, Latur, and Pangri in Maharashtra, and Adesar and Old Bhuj in Gujarat.”

A release from the NHSRCL also said, “This Early Earthquake Detection System, based on Japanese Shinkansen technology, will detect earthquake-induced tremors through primary 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.”
