Case Studies
7 Months Before Failure + Prevention
· SINKHOLE · 2025 ·
On September 24, 2025, a road section collapsed outside a major hospital in Bangkok, creating a 30-meter-wide, 20-meter-deep void that damaged utility poles and closed nearby streets. Caelus analyzed satellite data from the area, revealing consistent anomalous ground movement months prior to the collapse, indicating a precursor pattern.
8 Months Before Failure
SLOPE FAILURE · 2026 ·
In February 2026, a slope failure triggered by structural changes in the area caused significant damage, taking out two parallel roads. Early signs of the developing failure were already visible eight months before the collapse occurred, highlighting the importance of early detection and proactive monitoring.
Following the event, a comprehensive $25 million rehabilitation and restoration project was undertaken to stabilize the slope, restore critical infrastructure, and strengthen the area’s long-term resilience.
Prevention - Retaining Wall
RETAINING STRUCTURES · 2026
A 1.5-year-old retaining wall supporting a $145M interchange developed signs of geotechnical failure after its drains became clogged with vegetation.
Our team identified the developing failure and recommended immediate inspection, which lead to drainage clearance. Without intervention, the next rainy season could have pushed the wall beyond the point of no return.
12 Month Befoe Failure
BRIDGES COLLAPSE · 2025 ·
The Vadodara bridge collapsed in 2025, resulting in 20 fatalities and $25M in losses.
Analysis of the foundation movements showed that signs of the developing failure were visible 12 months in advance.
7 Month Befoe Failure
TAILING DAM · 2017 ·
In 2017, a tailings dam containing acidic water collapsed, releasing 250,000 square meters into the surrounding area and causing a major ecological disaster, with damages estimated at $150 million.
Nine years later, the reservoir remains out of service. Analysis of satellite data revealed hazardous movement in the dam wall seven months prior to the failure, which was missed due to long interval on-site monitoring.
9 Month Befoe Failure
CLIFF COLLAPSE · 2024 ·
Rising sea levels are accelerating coastal cliff erosion and retreat, putting critical infrastructure at increasing risk worldwide.
These failures can be detected months in advance, providing time for simple preventive measures before disaster occurs.
