WFP’s Automated Disaster Analysis and Mapping (ADAM) system provides data on a magnitude 5.5 earthquake that occurred on August 30, 2025, 99 km SE of Lata, Solomon Islands. The dataset includes the epicenter location, depth, and an estimate of 777 people impacted within a 50km radius. It was last updated on May 21, 2026.

Use Cases

• Map the earthquake's impact zone based on the provided epicenter coordinates and 50km radius.
• Estimate potential humanitarian needs based on the population count of 777 people within the impact area.
• Analyze seismic event characteristics using the provided magnitude and depth data.
• Integrate with other geospatial layers for risk and vulnerability assessment in the Solomon Islands region.

Strengths

• Includes specific event details: magnitude 5.5, depth of 51.899 km, and precise epicenter coordinates.
• Provides a concrete impact metric: 777 people estimated within the 50km radius.
• Data is produced by an operational UN system (WFP ADAM) for humanitarian emergencies.

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 does not specify the source or methodology for the population impact estimate.
