The City Beautiful is set to get an earthquake warning system. The equipment, which will be installed at the New Haryana Secretariat in Sector 17, will sound an alert around 30 seconds before an earthquake.
German company Secty Electronics Gmbh in collaboration with German Geo Research Centre (GFZ) has developed this system. An alert will be sounded when the sensors catch the vibrations of the P-wave or primary wave in the zone where an earthquake will take place. The P-waves are the first waves of an earthquake to arrive on a seismograph. These are followed by surface waves.
The system was assembled on the basis of research conducted by GFZ on earthquakes in the last 100 years. Chandigarh is in seismic zone IV, making it prone to earthquakes.
Managing Director of Secty Electronics Juergen Przybylak said, “Our system has not given any false alarms since 2006. The device can measure the expected damage to a building and gives a person valuable time to find a safe spot or leave the building before the earthquake sets in.”
The device will be installed after studying the layout of the building.
The sensors of the device can also sense the magnitude of the earthquake, which if greater then level 6 on the reading scale, will sound an alarm indicating that the earthquake will be destructive. The alarm can be adjusted according to the wishes of the client. The equipment also comes with speakers, which increases the range of the alarm.
The device helps in blocking and shutting down of gas pipelines, nuclear supplies, water supplies, etc. In case of leakage in a pipeline, supply to the pipeline is stopped and can only be resumed through a code. The cost of the device is between Rs 12 and Rs 14 lakh.
In India, Terra Techcom is involved in the business of setting up the device. Managing director Bijender Goel said that the system was currently working in 26 countries.
