Causes
Wildfires occur when vegetated areas are set alight and are particularly common during hot and dry periods. They can happen in forests, grasslands, brush, and deserts, and with enough wind, they can spread rapidly. The most common causes include lightning strikes, sparks during arid conditions, volcanic eruptions, and human-induced fires from arson or accidents.
Consequences
Unchecked, wildfires can devastate forests and other vegetated areas. When fires approach or occur near towns or cities, precautionary evacuations are often necessary, as the path of fires can be unpredictable. A significant side-effect of wildfires is smoke, which can spread far with the wind and pose serious respiratory hazards to nearby populations.
Satellite data
Satellites play a crucial role in mapping the extent of wildfires by observing smoke plumes and identifying burn scars. Thermal infrared sensors can detect heat, allowing for precise identification of fire locations. Data acquired through the International Charter: Space and Major Disasters can be relayed to firefighters on the ground within hours, assisting them in locating and combating fires effectively.
