A cooking fire at a homeless encampment sparked a wildfire last week that destroyed six homes in the Bel Air neighborhood of Los Angeles, authorities say.
Meanwhile the fifth-largest wildfire in Californian history burns northwest of the city, and keeps expanding and kept thousands out of their homes.
They are among a half-dozen fires that flared in Southern California last week and were driven by fiercely gusting Santa Ana winds.
Arson investigators determined that the Bel Air fire near the world-famous Getty museum was started by an illegal fire at a camp near a freeway underpass, city fire Captain Erik Scott said.
The camp was empty when firefighters found it but people apparently had been sleeping and cooking there for at least several days, he said.
Northwest of Los Angeles, firefighters protected foothill homes while the fire grew mostly into forest land, Santa Barbara County Fire Department spokesman Mike Eliason said.
Red Flag warnings for fire danger due to Santa Ana winds and a critical lack of moisture were extended into the week, with a possible increase in gusts Thursday into Friday.
Tens of thousands of people remain evacuated, including many from the seaside enclaves of Montecito, Summerland and Carpinteria and the inland agricultural town of Fillmore.
Still among evacuees due to smoke Tuesday were Rock and Roll Hall of Fame member Eric Burdon and his wife, Marianna, of Ojai. Last week, Burdon wrote on Facebook about having to flee and returning temporarily to find their home still standing with ashes all around.
"A week like this gives you the perspective that life is what truly matters," he wrote.
A photo accompanying the post showed his handprint and signature written in ashes.
