Overview
- The blaze ignited near the 600 block of Sandy Avenue and grew extremely fast on Monday, threatening neighborhoods and prompting mandatory evacuation orders across many Simi Valley and Thousand Oaks zones.
- Fire crews from Ventura County, Cal Fire and mutual‑aid partners deployed hundreds of personnel plus air tankers, helicopters and dozers while officials opened human and animal shelters for displaced residents.
- At least one home was destroyed and no fatalities have been reported, with schools closed and tens of thousands of people ordered or warned to leave their homes.
- Investigators are examining a possible human‑related ignition after a caller reported striking a rock with a tractor while clearing brush, but authorities have not confirmed that as the cause.
- Crews reported containment gains after calmer overnight conditions, with officials mapping the fire at roughly 1,300–1,700 acres and containment reported up to about 15 percent while evacuation orders remain in effect.
