India’s first use of seismometers for ‘early earthquake detection system’ in bullet train project

For the first time, India will install seismometers for a bullet train project to ensure the safety of passengers and critical infrastructure during earthquakes.

The foundation stone of the Mumbai-Ahmedabad high-speed rail corridor was laid in Ahmedabad in September 2017. The high-speed train will run at a speed of 320 kilometers per hour, covering a distance of 508 kilometers in 2 hours and 7 minutes.

How does a seismometer work?

According to the National High Speed ​​Rail Corporation Limited (NHSRCL), this early earthquake detection system, based on Japan’s Shinkansen technology, will detect earthquake-induced vibrations through primary waves and enable automatic power outage.

When a power outage is detected, emergency braking will be initiated and trains operating in the affected area will stop.

Where will the seismometer be installed?

Of the 28 seismometers, 22 will be installed along the route. Eight will be in Maharashtra – Mumbai, Thane, Virar and Bhoisal – Fourteen will be in Gujarat – Vapi, Bilimora, Surat, Bharuch , Vadodara, Anand, Mahabad and Ahmedabad. Seismometers will be installed in traction substations and switching columns along the route.

The remaining six seismometers, known as inland seismometers, will be installed in earthquake-prone areas – Hed, Ratnagiri, Latur and Pangri in Maharashtra and Ade in Gujarat Sal and old Bhuj.

Japanese experts surveyed the area near the MAHSR line and found that earthquakes above magnitude 5.5 have occurred in the past 100 years. The above site was selected after detailed surveys and soil suitability studies through microseismic tests.
