An 18-acre brush fire on the south end of Anza was 100% contained Thursday.
The non-injury Chapman Fire was reported at 12:52 p.m. Wednesday in the area of Chapman and Ramsey roads, on the eastern boundary of the Cahuilla Indian Reservation, according to the Riverside County Fire Department.
The agency said multiple engine and hand crews were sent to the location, preceded by Cal Fire aircraft, encountering flames moving at a rapid rate to the southeast in medium brush, with 10 properties in its path.
Six air tankers and two water-dropping helicopters initiated runs on the fire that decelerated it, enabling crews to establish tentative containment lines and prevent the flames from jumping a road.
No evacuation orders were issued, and no structures were damaged.
Electrical lines collapsed in the vicinity of the fire, and SoCal Edison de-energized transmission lines for public safety. Power was restored hours later.
Shortly before 6 p.m. Thursday, crews concluded mop-up operations along the fire lines.
The cause of the fire was under investigation.
