Vanuatu Earthquake Impact Analysis for September 2025 Event

A geospatial dataset documents the impact of a magnitude 5.5 earthquake near Liteu, Vanuatu, on September 27, 2025. The data, produced by the World Food Programme's Automated Disaster Analysis and Mapping (ADAM) system, includes the epicenter location and an estimate of 434 people impacted within a 50km radius. It was last updated in May 2026.

Use Cases

• Mapping earthquake impact zones based on the provided epicenter coordinates and radius.
• Estimating potential humanitarian needs based on the population count within the affected area.
• Integrating event data into disaster monitoring dashboards using the ADAM system's geospatial format.

Strengths

• Includes precise event details: magnitude 5.5, depth of 70.085 km, and exact latitude/longitude coordinates.
• Provides a concrete impact metric: 434 people estimated within the 50km impact radius.
• Sourced from an operational humanitarian analysis system (WFP ADAM).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified; the event occurred in 2025 but the record was updated in 2026.
