Days after they began, three separate named wildfires continue to ravage parts of Northern and Southern California. The largest and most catastrophic of the three has become the largest and deadliest wildfire in California's history. As of Tuesday afternoon, the Camp fire in Northern California had claimed 42 lives and burned 125,000 acres of land, according to state officials. In Southern California, the Woolsey fire claimed two additional lives, bringing the statewide death toll to 44 as of Tuesday afternoon as the fires continue to burn. Early analysis and estimates say these fires will result in major losses for P&C insurers, with Moody's analysts estimating insured losses of $3-6 billion.

Camp fire

Images of a completely devastated Paradise, California town depict the magnitude of the Camp fire. So far, the Camp fire has torched more than 125,000 acres and destroyed more than 6,500 homes and 260 commercial buildings in Northern California's Butte County. As of Tuesday afternoon, more than 15,500 structures remain threatened by the Camp fire in Northern California as the blaze was 30% contained, according to CAL Fire.

Woolsey fire

The Woolsey fire in Los Angeles and Ventura counties has left two dead as it has destroyed at least 435 structures and burned nearly 100,000 acres. As of Tuesday, the fire was only 35% contained. The fire threatens over 57,000 structures as it continues to ravage the greater Los Angeles area, including a town of particular concern for insurers: Malibu. In particular, the Camp fire continues to threaten more than 31,000 homes with an estimated rebuilding value of $7.28 billion, according to information from CoreLogic. The area is home to a number of celebrities and high-net-worth individuals with high-value properties. Several, including Miley Cyrus and Camille Grammer, have publicly announced the destruction of their homes. Because of the value of the houses and property in the area, analysts say the Woolsey fire could be among the costliest wildfires ever for home insurers. The Hill fire, which broke out Monday just west of the Woolsey fire, has burned 4,531 acres and was 90% contained as of Tuesday morning.
