The Mumbai-Ahmedabad High-Speed Rail Corridor, a prestigious bullet train project, is set to enhance passenger safety and protect critical infrastructure during seismic activities. This will be achieved through the installation of 28 Seismometers, forming an ‘Early Earthquake Detection System’.
This state-of-the-art system, inspired by Japanese Shinkansen technology, is designed to detect primary waves from earthquake-induced tremors. Upon detection, the system will trigger an automatic power shutdown, subsequently activating the emergency brakes. This will bring all trains within the affected area to a halt, ensuring passenger safety.
The system will comprise 28 seismometers, with 22 strategically placed along the rail alignment. Eight of these will be located in Maharashtra, specifically in Mumbai, Thane, Virar, and Boisar. The remaining fourteen will be installed across various locations in Gujarat, including Vapi, Bilimora, Surat, Bharuch, Vadodara, Anand, Mahemdavad, and Ahmedabad.
Anjum Pervez, the Managing Director of the National High-Speed Rail Corporation Ltd (NHSRCL), stated that the Early Earthquake Detection System represents a proactive approach to safeguard passengers and protect critical infrastructure. The seismometers, which will be installed in Traction Sub-Stations and Switching Posts along the alignment, are a testament to this innovative strategy.
In addition to the 22 alignment seismometers, six more (referred to as inland seismometers) will be installed in earthquake-prone areas. These include Khed, Ratnagiri, Latur, and Pangri in Maharashtra, and Adesar and Old Bhuj in Gujarat.
The selection of these sites was based on a detailed survey and soil suitability study conducted by Japanese experts. They examined areas near the MAHSR alignment that have experienced earthquakes of magnitudes greater than 5.5 in the past century. The chosen sites passed a micro tremor test, confirming their suitability for the installation of the seismometers.
