Long Beach firefighters will investigate the cause of three small fires Wednesday evening that started close together.
The first fire started after 5:30 p.m. near the 605 Freeway at the southeast corner of the El Dorado Nature Center. Three different spot fires burned a total of one acre.
Orange County Fire Authority firefighters helped extinguish the blaze on the ground and with aerial water drops from a helicopter.
At 8:58 p.m., the Long Beach Fire Department received a call about another fire burning eucalyptus trees and brush near Willow Street and the 405 Freeway.
Another fire started nearby at 9:56 p.m. at 29th Street and Redondo Avenue.
It is unknown what started the fires.
“Sometimes it’s wind and arcing wires,” said Brian Fisk, a Long Beach Fire Department public information officer. “It’s under investigation, but it is out of the ordinary.”
A few months ago, Long Beach firefighters fought a similar fire at El Dorado Nature Center that was later determined to be arson, Fisk said.
