A landslide is the downslope movement of rock, soil, or debris under gravity. Triggers include intense or prolonged rainfall, earthquakes, volcanic activity, rapid snowmelt, and slope disturbance by human activity. Landslides are among the most widespread geologic hazards, and often cascade from other events — a strong earthquake or a volcanic eruption can unleash thousands of slope failures.
Recent reports from NASA's Cooperative Open Online Landslide Repository (COOLR), ingested via the platform feeds addon and rendered from the record store at view time (no page churn).

| Type | Description |
| ------ | ------------- |
| Fall | Free-fall of rock or debris from a steep slope or cliff. |
| Slide | Movement of material along a distinct failure surface (rotational or translational). |
| Flow | Fast, fluid-like movement of saturated debris or mud (debris flow, mudflow, lahar). |
| Spread | Lateral extension over a weak or liquefied layer, often earthquake-triggered. |
| Source | Provider | Coverage |

| Global catalog | NASA COOLR / Global Landslide Catalog | Global, 2007–present |
| Hazard mapping & reports | USGS Landslide Hazards Program | United States |
| Rainfall triggers | NASA GPM / LHASA nowcast | Global |

The COOLR layer field names (event_title, event_date, landslide_category, …) should be verified against the live FeatureServer schema — ArcGIS field casing can differ per service revision. type is the domain label; schemaType stays Article until the framework implements the Event schema.org union type (ngdpbase#762).
