ADAM Earthquake Event: Magnitude 5.6 in Brazil, March 2025

WFP’s Automated Disaster Analysis and Mapping (ADAM) system provides data on a magnitude 5.6 earthquake that occurred on March 11, 2025, 81km south of Puerto Esperanza, Brazil. The dataset includes the epicenter coordinates (-10.4958, -70.6144), a depth of 640.71 km, and indicates 298 people were impacted within a 50km radius. It was last updated by the system on May 21, 2026.

Use Cases

• Map the earthquake's impact zone based on the provided epicenter coordinates and 50km radius.
• Analyze the relationship between earthquake depth and potential surface impact based on the 640.71 km depth figure.
• Estimate initial humanitarian needs based on the reported count of 298 impacted people.
• Integrate event data into larger disaster risk models using the standardized ADAM system format.

Strengths

• Includes specific event parameters: magnitude (5.6), depth (640.71 km), and precise epicenter coordinates.
• Provides a concrete impact metric, reporting 298 people affected within a 50km radius.
• Originates from an operational UN system (WFP ADAM) designed for humanitarian 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 statistical modeling.
• The description is for a single event; the dataset's full temporal and geographic scope is unclear.
