*What if geological anchors could sense impending landslides? Embedded strain sensors and IoT intelligence enable earlier warnings, reducing risks to lives and infrastructure.*
Landslides remain one of the most destructive geotechnical hazards in hilly or mountainous areas. Landslides are triggered by precipitation, seismic activity, or changes in groundwater levels, leading to loss of life, damage to infrastructure, and long-term economic implications. Traditional early warning systems often depend heavily on surface displacement markers, inclinometers, rainfall thresholds, or satellite-based remote sensing. Although useful, they are usually unsuitable for detecting internal stress redistribution or subsurface deformation that occurs before catastrophic slope collapse.

An early warning system

A newly developed Internet of Things (IoT)-enabled landslide early warning system using smart geological anchors with embedded strain-sensing electronics tackles the gap directly by analysing the mechanical behaviour occurring beneath the soil and rock mass in the subsurface.



Rather than considering structural anchors as inert reinforcing structures, the system converts them into intelligent sensing nodes that can support real-time deformation monitoring and predictive failure evaluation.

The key idea: turning anchors into sensors

Geological anchors and rock bolts are widespread in slope stabilisation. Traditionally, they are only used to transfer tensile forces to secure strata. Today’s system incorporates embedded strain-sensing electronics through these anchors, resulting in a dual-functioning hardware system.

Each Smart Geological Anchor Comprises
- A high-strength anchor body bonded to surrounding soil or rock
- An embedded strain sensor
