Indonesia Earthquake Impact Analysis for April 20 2025 Event

A geospatial dataset from the WFP's Automated Disaster Analysis and Mapping (ADAM) system details the impact of a magnitude 5.4 earthquake in Indonesia on April 20, 2025. The data includes the epicenter location at latitude -3.3636, longitude 131.0017, a depth of 10.0 km, and indicates 21,912 people were impacted within a 50km radius. 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 potential humanitarian needs based on the reported population of 21,912 people impacted.
• Analyze seismic event characteristics such as magnitude and depth for risk modeling.
• Integrate with other geospatial layers for comprehensive disaster analysis as suggested by the ADAM system's purpose.

Strengths

• Includes specific factual data: magnitude 5.4, depth 10.0 km, and 21,912 people impacted.
• Provides precise geographic coordinates for the epicenter: latitude -3.3636, longitude 131.0017.
• Originates from an operational humanitarian analysis system (WFP ADAM), suggesting a defined collection methodology.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset scale are unknown, which may limit suitability assessment.
• The description metadata is limited to a single event; the full data structure requires inspection.
