Landslide hazards sourced from the NASA Global Model of Models LHASA (Landslide Hazard Assessment for Situational Awareness). These hazards represent areas where landslide conditions have been detected or forecast, with severity levels indicating the assessed risk to affected populations and infrastructure.
Landslide-Specific Properties
Incident Data
The incident.properties object for landslide hazards contains metadata from the LHASA system describing the detected landslide event and its severity classification.
Key incident properties for landslides include:
senderName - Source system identifier ("The NASA Global Model of Models LHASA")
incidentSeverity - Severity classification of the incident (e.g., "WARNING")
masterIncidentId - Unique identifier linking related incident records
eventDate - ISO 8601 timestamp for when the landslide event was first detected
createDate - ISO 8601 timestamp for when the hazard record was created
reportDate - ISO 8601 timestamp for the latest report on this hazard
Features
Landslide features typically include INCIDENT polygons showing affected areas. The features FeatureCollection contains multiple feature types:
INCIDENT - Point geometry at the hazard centroid with featureType: "INCIDENT"
SMART_ALERT - MultiPolygon geometry representing the combined alert area with featureType: "SMART_ALERT"
EXPOSURE_AREA - MultiPolygon geometry representing the exposure assessment area, with properties including exposureDescription (e.g., "SEVERE"), exposureLevel (numeric severity tier), and featureType: "EXPOSURE_AREA"
Exposure Areas
Single level - Combined landslide polygons at Watch or Warning severity. The exposureAreas FeatureCollection contains one feature with an exposureLevel property (e.g., level 3 for SEVERE) covering the full extent of the detected landslide-prone area.
Sample Response
Note: Coordinate arrays have been replaced with [...] for brevity. In actual API responses, alertGeometry, features, and exposureAreas contain complete GeoJSON coordinate arrays. The features.metadata and incident.properties objects have been truncated with "..." to show only key fields. The source field is null for LHASA landslide hazards. Population values within exposureAssessment are integers; capital.school and capital.hospital are counts of exposed facilities.
