Person missing in Vic bushfires

A person is missing as a bushfire tears through more than 2500 hectares of land in central Victoria.

Country Fire Authority crews and police are searching for the person after at least one house and numerous sheds and outbuildings were razed in the fire, near Lancefield, on Tuesday afternoon. The blaze was sparked by a controlled burn on public land which jumped containment lines.

CFA incident controller Greg Murphy confirmed the search.

"A person is currently unaccounted for," Mr Murphy told AAP.

Mr Murphy said it's possible the missing person has failed to link up with friends or family or is already in a relief centre for evacuees at Gisborne.

"We're not waiting until daylight to find out, and we have a number of aspects that we are working through now," Mr Murphy said.

Crews won't know until daylight whether more than one home has been lost.

Mr Murphy said a ground and aerial assessment will take place at dawn.

An emergency warning is in place for the fire affecting Pastoria East, Nulla Vale and Benloch.
