A wildfire in Ventura County, California, has prompted thousands of evacuations and destroyed dozens of homes.

The Mountain Fire was burning in a region that has seen some of California’s most destructive fires over the years. The fire swiftly grew from less than half a square mile (about 1.2 square kilometers) to more than 16 square miles (41 square kilometers) in little more than five hours on Wednesday.

A Southern California wildfire has destroyed 132 structures, mostly homes, in less than two days, fire officials said Thursday as raging winds were forecast to ease.
