California Wildfires Force 10,000 Simi Valley Residents to Evacuate; Santa Rosa Island Blaze Uncontained

Satellite imagery has revealed the extent of two wildfires currently burning in Southern California. The Sandy Fire, which ignited on Monday morning, has forced the evacuation of over 10,000 homes in Simi Valley, north-west of Los Angeles, and surrounding communities.

California Governor Gavin Newsom confirmed the Sandy Fire's rapid spread, with officials reporting 1,364 acres (550 hectares) consumed and zero containment as of Tuesday morning. Some 750 firefighters are battling the blaze, supported by night-flying water-dropping helicopters.

The Simi Valley Police Department indicated the fire may have started after an individual struck a rock with a tractor. High winds on Monday morning contributed to its initial rapid expansion, although conditions reportedly eased later in the day.

Separately, a fire on Santa Rosa Island, part of the Channel Islands National Park off the coast of Los Angeles, has incinerated 14,600 acres (6,000 hectares). First reported on Friday, this blaze also remains entirely uncontained, with 70 firefighters and park rangers deployed. The island, largely uninhabited, is known for its unique ecosystem.

Both fires show active hotspots continuing to spread, according to NASA's wildfire monitoring platform. Los Angeles Mayor Karen Bass stated that while the Sandy Fire is not expected to reach the city, evacuation warnings have been issued as a precautionary measure.
