Ecuador Earthquake Impact Analysis for September 2025

A magnitude 5.4 earthquake occurred on September 05, 2025, 34km NW of Ayangue, Ecuador, impacting an estimated 346,460 people within 50km. The dataset is produced by the World Food Programme's Automated Disaster Analysis and Mapping (ADAM) system for rapid humanitarian response. It was last updated on May 21, 2026.

Use Cases

• Modeling population exposure to seismic hazards based on the reported impact radius of 50km.
• Prioritizing emergency resource allocation based on the estimated 346,460 affected people.
• Mapping the disaster footprint for situational awareness based on the provided epicenter coordinates (latitude -1.8831, longitude -81.0479).
• Analyzing earthquake characteristics for risk assessment based on the reported magnitude of 5.4 and depth of 0.0 km.

Strengths

• Includes specific impact metrics, such as 346,460 people affected within a 50km radius.
• Provides precise geographic coordinates for the epicenter (latitude -1.8831, longitude -81.0479).
• Contains detailed event parameters including magnitude (5.4), depth (0.0 km), and date (Sep 05, 2025).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Description metadata is limited; actual data quality and completeness require manual inspection after download.
