Slope Stability & Landslide Early Warning

Slope stability & landslide early warning

Steep slopes often fail slowly at first, then suddenly. Buried or surface-mounted STS sensors track the ground's rotation through the quiet phase — creep of a few millimetres that is easy to miss by eye — and can support debris-flow and landslide alarms while evacuation is still feasible.

Why slopes need in-place angle measurement

Rainfall, excavation and erosion weaken slopes gradually, and the visible signs — cracks, bulges, leaning trees — often appear only a short time before failure. In-place STS6 tilt sensors measure the rotation of the ground and of retaining structures continuously, catching the quiet creep phase of a few millimetres so the acceleration that precedes failure is detected early — adding valuable time to the warning.

Typical use cases

One sensor, four lines of defence

Surface creep monitoring — STS6 units on stable benchmarks detect rotational movement of the slope surface from fractions of a degree.
Retaining wall & pile tilt — sensors on retaining walls and anti-slide piles reveal growing earth pressure before the wall bows visibly.
Debris-flow early warning — thresholds on tilt rate and accumulated change trigger automatic alarms for downstream communities and road closures.
Post-fire & post-quake watch — after wildfire or earthquake, quickly deployed sensor grids watch burned or loosened slopes through the dangerous first rainy season.
