Want to predict wildfire severity? Research says look to the state of vegetation

Phys · · 466 words · By Rebecca Owen

Researchers analyzed three January 2025 wildfires in Los Angeles using satellite data to predict burn severity. The study, published in AGU Advances, found that pre-fire fuel conditions, specifically vegetation state, were the primary drivers of fire severity.
