El Salvador Earthquake Impact Analysis for June 18 2025

A geospatial dataset from the World Food Programme's ADAM system details the impact of a magnitude 5.4 earthquake near Usulután, El Salvador, on June 18, 2025. The data includes the epicenter location, depth, and an estimate of 324,483 people impacted within a 50km radius. It was last updated by the WFP Automated Disaster Analysis & Mapping system on May 21, 2026.

Use Cases

• Modeling population exposure to seismic hazards based on the reported impact radius and population count.
• Mapping the geographic distribution of earthquake effects using the provided epicenter coordinates and depth.
• Prioritizing emergency resource allocation based on the estimated scale of impacted people.
• Integrating event data into larger disaster risk models using the standardized ADAM system identifiers.

Strengths

• Includes specific event parameters: magnitude 5.4, depth of 81.191 km, and precise epicenter coordinates (13.0931, -88.5664).
• Provides a concrete impact metric, estimating 324,483 people affected within 50km.
• Sourced from an operational humanitarian analysis system (WFP ADAM), suggesting a standardized collection method.

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 metadata is limited to a single event; the full data schema is not detailed.
