23 fire pixels detected · FRP: 83 MW · ~3.2 km²

Geographic Context

This fire event occurred near Vila Velha (approximately 11 km away) in Brazil, an area where deforestation, agricultural practices, and dry season conditions contribute to wildfire frequency. An estimated 939.0K people live within 35 km of the event location, placing this in the "severe" population impact tier.

Event Assessment

This event is a wildfire detected across 23 satellite thermal detection pixels, indicating an active fire zone. Calamity.live has classified it as "high" severity with a severity value of 39.616. The computed Calamity Score is 44 out of 100, reflecting a moderate-impact event. The primary scoring components are: population (85), intensity (40), historical (20). Data for this event was sourced from firms, one of the 250 scientific monitoring sources aggregated by Calamity.live.

Regional Monitoring Context

Brazil 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.
