The Risk Beneath: What Causes Sinkholes?
Sinkholes and subsurface collapses occur when the ground underneath a structure loses its support causing sudden, often catastrophic failure. These collapses may happen without surface warning and are among the most unpredictable ground movement risks insurers face.
Primary triggers include:
-
Natural Groundwater Changes:
Water dissolves soluble bedrock (e.g., limestone, gypsum), forming underground voids invisible from above. -
Aging or Damaged Infrastructure:
Leaking sewer lines, storm drains, and water pipes erode the subsoil over time, accelerating collapse. -
Construction and Excavation Activity:
Tunneling, underground metro systems, or even high-load construction can destabilize subsurface layers, leading to sinkholes.
Despite their sudden appearance, sinkholes often develop over time—and can be detected before failure occurs.
Collapsed without warning—but not without signs
Global Financial Impact
Subsidence activity visible on satellite but hidden from sight at street level
While sinkholes may seem localized, their cumulative impact is global - and growing:
-
$1.2 billion in annual global losses related to sinkholes
-
Florida (2006–2010): Over 24,000 claims, totaling $1.4 billion
-
Average payout per claim: $139,000 (pre-reform), excluding litigation and investigation costs
-
Urban expansion + extreme weather = rising sinkhole frequency and escalating pressure on property and casualty insurers
Sinkhole risk is no longer limited to karst regions, it is expanding alongside human infrastructure.
Caelus transforms sinkhole risk into actionable data through AI-enhanced satellite monitoring.

Multi-Sensor Integration:
We combine radar (InSAR), optical, LiDAR, and ground-penetrating signals to build a full picture of subsurface stability. -
AI-Powered Forecasting:
Our platform analyzes historical subsidence patterns, geotechnical data, and environmental indicators to identify early warning signs. -
Scalable Urban Coverage:
Monitor entire cities for signs of subterranean collapse risk before damage or liability occurs.
By converting uncertainty into visibility, we allow underwriters, reinsurers, and infrastructure stakeholders to:
-
Price risk more accurately
-
Reduce high-cost claims
-
Improve loss ratios through early mitigation
Our Solution: Make Sinkholes Predictable, Manageable, and Insurable
. The event occurred just meters from major high-rise buildings and arterial roads, and was directly linked to tunneling activity for the Red Line of the Tel Aviv Metro.
What satellites had detected months earlier subtle but consistent subsidence was never acted upon.
Had this data been integrated into underwriting or infrastructure monitoring tools, timely reinforcement could have prevented the collapse.
Estimated loss: $10 million, including infrastructure damage, emergency response, and business interruption.
This incident underscores a fundamental truth: in dense urban areas, subsurface instability isn’t just a geotechnical hazard—it’s a high-exposure financial liability.
