KUALA LUMPUR, June 22 -- Researchers at Universiti Malaya here have been testing an optical fibre-based monitoring system that can predict subtle ground movements, potentially providing early warning signs of instability before disaster strikes.

Muhammad Syamil Mohd Sa'ad of the university's Photonics Research Centre (PRCUM) said the technology is designed to predict gradual movements that may signal a slope is becoming unstable, allowing engineers and authorities to monitor potential risks over time.

How does the system work?

"Unlike conventional sensors that rely heavily on electronic components installed in the field, the system uses light transmitted through optical fibres to measure changes in the surrounding environment.

"As the...
