Santa Coloma de Queralt

General information

Category: Wildfire
Fire classification: Deep PyroCu / PyroCb
Country: Catalonia, Spain
Year: 2021

The Santa Coloma de Queralt wildfire originated in a cereal field, and the presence of a moderate west wind contributed to its rapid spread. The incursion of the fire into the forest mass served to augment its intensity, with the advent of pyroconvective phenomena (overshooting PyroCu). On the second day of the fire, following an intense period of propagation, the transition to PyroCB occurred.
