Tonga Earthquake Event of March 2026 with Geospatial Impact Data

A magnitude 7.6 earthquake occurred 153 km west of Neiafu, Tonga, on March 24, 2026. The dataset, produced by the WFP's Automated Disaster Analysis and Mapping (ADAM) system, provides geospatial coordinates and reports zero people impacted within a 50km radius. It was last updated on May 21, 2026.

Use Cases

• Map the earthquake's epicenter and affected area based on the provided latitude and longitude coordinates.
• Assess initial reported human impact for rapid response planning based on the stated population impact within 50km.
• Integrate event data into disaster risk models based on the magnitude, depth, and location details.

Strengths

• Specific magnitude (7.6) and depth (237.549) are provided for the event.
• Precise geographic coordinates (latitude -18.7004, longitude -175.4349) define the epicenter.
• Data is sourced from an operational humanitarian analysis system (WFP ADAM).

Limitations

• The description states zero people were impacted within 50km, which may indicate limited initial assessment or a remote location.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
