IIT-Madras researchers develop new approach for 'accurate detection' of earthquakes

The proposed solution results in accurate detection and picking of the first waves in earthquake signals, which provide a small time window for charting measures to save lives, say researchers

Indian Institute of Technology-Madras researchers claim to have developed a new approach for accurate detection of earthquakes, which they say will provide a small lead time to save 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 till the destructive surface waves hit the ground, they said.

“The proposed framework is not necessarily limited to the detection of seismic events but is generic and can be used for fault detection and isolation in other domains as well,” Prof Arun K Tangirala, Department of Chemical Engineering, IIT Madras, said.

The research was carried out by Kanchan Aggarwal, a PhD Scholar, under the guidance of Tangirala. The findings have been published in the peer-reviewed open access scientific journal PLOS ONE.
