PORTLAND — Ten strike teams from all over the state are on their way to help California firefighters battle several massive blazes north of Los Angeles.

The Oregon Fire Marshal said Wednesday it is also sending heavy equipment to help.

The largest and most destructive of the fires, an 85-square-mile wildfire in Ventura County northwest of Los Angeles, had nearly reached the Pacific on Tuesday night after starting 30 miles (48 kilometers) inland a day earlier.

Strikes teams from Oregon will come from Lane, Multnomah, Washington, Linn, Marion, Clackamas, Klamath and Yamhill counties.

A combined team from Polk, Linn, and Benton counties and a team from the Rogue Valley area are also en route.

State fire officials say five more strike teams will be dispatched later Wednesday.
