Indonesia Earthquake Impact Data for March 31, 2025

A geospatial dataset from the WFP's ADAM system documenting a magnitude 5.6 earthquake near Gg. Perintis, Indonesia, on March 31, 2025. The data includes the epicenter coordinates, depth, and an estimate of 80,865 people impacted within a 50km radius. It was last updated on May 21, 2026.

Use Cases

• Map the affected population density based on the reported 80,865 impacted people within 50km.
• Analyze earthquake characteristics and location using the provided magnitude, depth, and epicenter coordinates.
• Model humanitarian response needs for sudden-onset disasters based on the automated analysis framework described.
• Integrate event data into regional seismic risk assessments using the standardized geospatial format.

Strengths

• Provides specific event parameters: magnitude 5.6, depth of 28.472 km, and precise epicenter coordinates.
• Includes a concrete impact metric: 80,865 people estimated within the 50km impact zone.
