How We Translate
Complex Data for You.
We simplify official government datasets so you can make informed decisions about your home's safety and value.
Official Sourcing
We only utilize authoritative datasets from FEMA, NOAA, and USGS. We do not use unverified third-party models.
Geospatial Precision
Risk is calculated based on exact geographic coordinates, ensuring property-level relevance rather than just ZIP-code averages.
Score Normalization
Disparate data points are normalized into a unified 0-100 scale for intuitive comparison across different risk categories.
How We Analyze Data
Our system connects directly to official public databases to help you understand your local environment. We don't just show numbers; we provide context.
FEMA National Risk Index (NRI)
The baseline for regional risk frequency and social vulnerability.
Layer Integration
We integrate NRI data to establish base frequency scores for 18 natural hazards. This includes historical annualized loss values and community resilience metrics which influence the final composite score.
- Annualized Loss
- Social Vulnerability
- Community Resilience
- Hazard Frequency
NOAA Historical Intelligence
Analyzing decades of storm events and wind probabilities.
Temporal Analysis
By querying historical storm tracks and peak wind intensity data, we calculate localized exposure probabilities for hurricanes, tornadoes, and severe convective storms.
USGS Earthquake Hazards
Seismic probability and peak ground acceleration (PGA).
Structural Impact Modeling
Our earthquake scoring factors in the distance to known fault lines and the Peak Ground Acceleration (PGA) probabilities for a 50-year horizon, as defined by USGS National Seismic Hazard Models.
Note: Soil liquefaction and localized geological variables may affect final structural impact.
Normalizing Risk: The 0-100 Scale
To make complex environmental data actionable, we normalize disparate metrics into a consistent percentile-based score.
Commitment to Integrity
CheckDisaster is an independent platform. We do not modify government data to fit any commercial agenda. Our mission is to provide the most transparent view of property exposure possible, enabling users to make informed, data-backed decisions.
