SAN FRANCISCO, Oct. 16 (Xinhua) -- A wildfire starting Friday from a prescribed burn in Santa Cruz County, U.S. northern California, was 83 acres (about 0.33 square km) large and 25 percent contained, fire officials said on Saturday.
The Estrada fire, burning between Watsonville and Morgan Hill above Hazel Del Road near Santa Clara County, was "part of the" Estrada Ranch Prescribed Burn, according to Cecile Juliette, a spokesperson for the San Mateo and Santa Cruz Unit (CZU) of the California Department of Forestry and Fire Protection (Cal Fire).
Prescribed burns are "intended to reduce fuel accumulations and restore and enhance grassland," officials said in a statement.
Officials said there will be a full investigation to determine what went wrong.
Four zones in Santa Cruz County are still under an evacuation order because of the blaze.
