Papua New Guinea Earthquake Impact Analysis for April 2025

5376 people were impacted within 50km of a magnitude 5.7 earthquake southwest of Long Island on April 22, 2025. The dataset, produced by the WFP's Automated Disaster Analysis and Mapping (ADAM) system, provides geospatial information on the event's epicenter and impact. 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 population exposure for rapid needs assessment based on the reported impacted population count.
• Analyze seismic event characteristics for disaster risk reduction planning based on the magnitude and depth data.

Strengths

• Includes specific impact metrics, such as 5376 people affected within a 50km radius.
• Provides precise geographic coordinates (-5.4843 latitude, 147.0064 longitude) for the earthquake epicenter.
• Originates 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.
• Data may reflect geographic and temporal bias inherent to the specific event and reporting system.
