ADAM: Earthquake Impact Data for Indonesia, August 2025

WFP’s Automated Disaster Analysis and Mapping (ADAM) system provides data on a magnitude 5.8 earthquake near Poso, Indonesia, on August 16, 2025. The dataset includes the epicenter location, depth, and an estimate of 125,469 people impacted within a 50km radius. It was last updated by the system on May 21, 2026.

Use Cases

• Map population exposure based on the provided 50km impact radius and epicenter coordinates.
• Model seismic hazard and risk for the Sulawesi region based on the event's magnitude and depth.
• Integrate with other geospatial layers for multi-hazard analysis using the provided GEOJSON format.
• Assess immediate humanitarian needs by correlating the impacted population figure with local infrastructure data.

Strengths

• Includes specific event parameters: magnitude 5.8, depth of 10.0 km, and precise epicenter coordinates.
• Provides a concrete impact estimate of 125,469 people within the 50km radius.
• Data is produced by an operational UN system (WFP ADAM) designed for emergency analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for statistical modeling.
• The description metadata is limited; actual data quality and attribute completeness require manual inspection.
