Canyon Fire becomes one of four wildfires burning across Southern California on Thursday, forcing evacuations east of Lake Piru as crews battle flames.

Since it started on Friday afternoon, the Gifford Fire -- which is situated within the Los Padres National Forest in Solvang, California -- has burned 83,933 acres and has only reached 9% containment, prompting evacuation orders for those in the Santa Barbara and San Luis Obispo counties, officials said.

Wildfires that tore through Los Angeles early this year may have caused hundreds more deaths than official reports show, Boston University researchers suggest.
