Vanuatu Earthquake Impact Data for December 23, 2025

2852 people were impacted within 50km of a magnitude 5.6 earthquake that occurred on December 23, 2025, 61km SW of Gaua Island, Vanuatu. The dataset, provided by the WFP's Automated Disaster Analysis and Mapping (ADAM) system, contains geospatial and socio-economic information collected following the sudden onset emergency. It was last updated on May 21, 2026.

Use Cases

• Map the affected population based on the reported 50km impact radius.
• Analyze earthquake characteristics such as magnitude and depth for hazard modeling.
• Assess potential humanitarian needs using the socio-economic information mentioned in the description.
• Integrate event location data (latitude -14.7032, longitude 167.1651) with other geospatial layers.

Strengths

• Provides specific impact metrics, including 2852 affected people and a 50km radius.
• Includes precise event parameters: magnitude 5.6, depth 170.96 km, and exact epicenter coordinates.
• Data is generated by an operational humanitarian system (WFP ADAM) 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.
• The dataset describes a single event, limiting temporal scope for longitudinal analysis.
