4 fire pixels detected · FRP: 189 MW · ~0.6 km²
Geographic Context
This fire event occurred near Arcos de Valdevez (approximately 13 km away) in Portugal, an area in the Mediterranean climate zone where hot, dry summers elevate wildfire risk significantly. An estimated 16.9K people live within 20 km of the event location, placing this in the "significant" population impact tier.
Event Assessment
This event is a significant wildfire detected by satellite with a fire radiative power of 189 MW, suggesting active, intense burning across multiple detection pixels. Calamity.live has classified it as "high" severity with a severity value of 41.792. The computed Calamity Score is 39 out of 100, suggesting contained impact at this time. The primary scoring components are: intensity (60), population (40), historical (30). Data for this event was sourced from firms, one of the 250 scientific monitoring sources aggregated by Calamity.live.
Regional Monitoring Context
Portugal 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.

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.
