Geographic Context

This fire event occurred near Siloam Springs (approximately 47 km away) in United States, an area where drought conditions, high temperatures, and dry vegetation frequently combine to create elevated wildfire risk. An estimated 818 people live within 50 km of the event location, placing this in the "minor" population impact tier.

Event Assessment

This event is a large-scale wildfire with a fire radiative power (FRP) of 2015 MW, indicating extreme heat output and rapid fire spread. Calamity.live has classified it as "critical" severity with a severity value of 100. The computed Calamity Score is 63 out of 100, reflecting a moderate-impact event. The primary scoring components are: intensity (95), historical (80), cascading (70). Data for this event was sourced from firms, one of the 250 scientific monitoring sources aggregated by Calamity.live.

Regional Monitoring Context

United States has a documented history of fire events. Wildfire activity in the region is monitored through NASA FIRMS (Fire Information for Resource Management System), which provides near-real-time active fire data from MODIS and VIIRS satellites. Fire behavior is influenced by vegetation type, moisture content, wind patterns, and terrain — all factors that determine whether an initial ignition becomes a major event.

Cascade Risk Analysis

This event may trigger secondary hazards through cascade effects. Cascade detection is an automated process that evaluates how primary disasters can trigger secondary events — for example, earthquakes triggering landslides, or volcanic eruptions causing lahars and pyroclastic flows. These secondary hazards can sometimes pose a greater threat than the initial event, particularly in mountainous terrain or densely populated areas.

Safety Information

If a wildfire is approaching: follow evacuation orders immediately. Do not wait to see the fire. Close all windows and doors, remove combustible materials from around your home, and have an emergency go-bag ready. Air quality can deteriorate rapidly even at distance from the fire front — monitor local air quality advisories.
