IIT Madras researchers develop new method to detect earthquakes
- This lead time is enough to shut down nuclear reactors, metro services, park elevators and other services that could save countless lives
- The findings of their study were published in the journal PLOS ONE
- The new method is accompanied by sound features, which lead to less external sensitivity or a stronger detection
Researchers at Indian Institute of Technology (IIT), Madras, have developed a new approach for detection of earthquakes that provides a small lead time which could be helpful in saving lives.
“An estimate of accurate time of arrival of non-destructive waves of earthquakes would not only help in developing a robust early warning system but also gives a lead time of approximately 30 seconds to 2 minutes (range may vary depending on the distance of epicentre from the monitoring site) till the destructive surface waves hit the ground,” an official statement said.
This lead time is enough to shut down nuclear reactors, metro services, park elevators and other services that could save countless lives.
IIT Madras PhD specialist Kanchan Aggarwal conducted research under the guidance of Prof Arun K Tangirala, Department of Chemical Engineering. The findings of their study were published in the journal PLOS ONE.
Tangirala, while highlighting the practical applications of the study, said, “The proposed framework is not necessarily limited to the detection of seismic events but can be used for fault detection and isolation in other domains as well. Furthermore, the framework can incorporate any predictive models, including machine learning and deep learning models, which will reduce human intervention in detection."
The new method is accompanied by sound features, which lead to less external sensitivity or a stronger detection. Research also provides flexibility for flexible band, with both high and low frequency levels at each level, leading to accurate detection.
“Information of P-wave arrival is crucial in determining other source parameters of the event such as magnitude, depth and epicentre location. Therefore, a solution to the P-wave detection problem that is robust, accurate and precise is essential in order to estimate the event details correctly and to reduce the damage caused by the earthquake or other triggered events,” said Aggarwal.
