ADAM Earthquake Event: Magnitude 5.5 Near Buol, Indonesia, 2026

A magnitude 5.5 earthquake impacted an estimated 52,140 people within 50km of its epicenter in Indonesia on February 19, 2026. WFP’s Automated Disaster Analysis and Mapping (ADAM) system collected and mapped this geospatial and socio-economic information following the sudden onset emergency. The dataset was last updated on May 21, 2026.

Use Cases

• Modeling population exposure to seismic hazards based on the reported impact radius of 50km.
• Mapping disaster response priorities using the precise epicenter coordinates (latitude 1.3709, longitude 122.1572).
• Analyzing the relationship between earthquake depth (10.0 km) and ground-level impact for similar magnitude events.

Strengths

• Impact estimate quantifies the scale of the event, reporting 52,140 people affected.
• Provides precise geographic coordinates (latitude 1.3709, longitude 122.1572) for the epicenter.
• Includes key seismic parameters like magnitude (5.5) and depth (10.0 km).

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.
