Knowing Earthquake Information In Time, China Railway Is Safer

China Earthquake Administration and China Railway Corporation signed a strategic cooperation agreement on high-speed railway earthquake warning in Beijing on the October, 23rd. They plan to achieve earthquake rapid information access in 2018, and officially provide earthquake intensity rapid warning and early warning information services to the national high-speed rail in 2021.

China's geological structure is complex, and seismic activity has the characteristics of high frequency, shallow source, high intensity and wide distribution. According to statistics, about one-quarter to one-third of the major earthquakes in the global mainland have occurred in China. The earthquake is difficult to predict and is extremely destructive. It is also pronet to secondary disasters such as fires, mudslides and landslides. Earthquakes are extremely harmful to transportation. Without timely earthquake warning and emergency response, it will bring incalculable losses to society. Therefore, as a transportation enterprise department such as roads, railways, and aviation, it is responsible for social public safety by actively proactively alerting geological disasters and preparing emergency plans.

According to the railway development plan, China's high-speed railway will reach more than 30,000 kilometers in 2020, covering more than 80% of large and medium-sized cities. With the continuous extension of the railway network, the geological terrain through which the high-speed railway line passes is becoming more and more complex. The high-speed railway seismic monitoring and early warning is particularly important. The high-speed railway runs fast and encounters earthquake disasters during the operation. If earthquake warning can be made a few seconds or even tens of seconds before the destructive vibration arrives, and the emergency braking measures are implemented on the train in time, the car can be avoided to the utmost extent. The tragedy of ruining people, In the event of an earthquake disaster during operation, if an earthquake warning can be made a few seconds or even tens of seconds before the destructive vibration arrives, and the emergency braking measures are applied to the train in time, the secondary damage can be prevented or mitigated and protect the safety of high-speed railway operations better.

The high-speed railway earthquake early warning system jointly promoted by China Earthquake Administration and China Railway Corporation is of great significance to China's railway development and earthquake prevention and disaster reduction undertakings.
