Tanzania Earthquake Impact Analysis for 85,522 People, January 2026

85,522 people were impacted within 50km of a magnitude 5.4 earthquake near Somanga, Tanzania, on January 20, 2026. The dataset is produced by the World Food Programme's Automated Disaster Analysis and Mapping (ADAM) system for rapid humanitarian assessment. It was last updated on May 21, 2026.

Use Cases

• Modeling population exposure to seismic hazards based on the reported 50km impact radius.
• Prioritizing emergency resource allocation based on the quantified impact of 85,522 people.
• Mapping the disaster footprint for situational awareness using the provided epicenter coordinates.
• Integrating event data into early warning systems based on magnitude, depth, and location parameters.

Strengths

• Includes specific impact metrics, such as 85,522 people affected within a defined 50km radius.
• Provides precise geolocation data with latitude (-8.3278) and longitude (39.3491) for the epicenter.
• Contains key event parameters including magnitude (5.4), depth (10.0 km), and date (Jan 20, 2026).
• Sourced from an operational humanitarian 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 large-scale modeling.
• Data may reflect geographic and temporal bias inherent to the specific event and reporting system.
