The Camp Fire that has burned across more than 150,000 acres in California and become the deadliest blaze in state history has finally been contained, officials said Sunday.

California Fire officials said the blaze at Camp Creek Road near Jarbo Gap in Butte County, which had been burning since November 8, is "now 100 percent contained."

It has burned across a total of 153,336 acres, destroying 13,972 residences, 528 commercial and 4,293 other buildings. The nation's deadliest wildfire in the past century has killed at least 84 people, and more than 560 are still unaccounted for.

It comes after reports earlier Sunday that rescue workers are still combing through muddy ash and debris left behind by the catastrophic blaze for signs of human remains.

Crews resumed the grim work as the rain cleared out of the devastated town of Paradise. Some were looking through destroyed neighborhoods for a second time as hundreds of people remain unaccounted for. They were searching for telltale fragments or bone or anything that looks like a pile of cremated ashes.

The flames ignited November 8 in the parched Sierra Nevada foothills and quickly spread across 240 square miles.

The town of Paradise was almost completely destroyed in just one day. The fire burned down nearly 19,000 buildings, most of them homes, and displaced thousands of people, the California Department of Forestry and Fire Protection said.

The two-week firefight got a boost earlier in the week from the first significant storm to hit California. It dropped an estimated 7 inches of rain over the burn area over a three-day period without causing significant mudslides, Hannah Chandler-Cooley of the National Weather Service said.

The rain helped extinguish hotspots in smoldering areas, and containment increased to 95 percent. Despite the inclement weather, more than 800 volunteers kept searching for remains.

Crews worked on-and-off amid a downpour Friday. While the rain made everybody colder and wetter, they kept the mission in mind, Chris Stevens, a search volunteer who wore five layers of clothing to keep warm, said.

"It doesn't change the spirits of the guys working," he told the Associated press. "Everyone here is super committed to helping the folks here."

His search crew went home to Orange County on Saturday after completing its assignment. Authorities also lifted evacuation orders for certain sections of Paradise.

In Southern California, more residents have returned to areas evacuated in a destructive fire as crews repaired power, telephone and gas utilities.

Los Angeles County sheriff's officials said they were in the last phase of repopulating Malibu and unincorporated areas of the county. At the height of the fire, 250,000 fled their homes.

Flames erupted Nov. 8 just west of Los Angeles and burned through suburban communities and wilderness parklands to the ocean. Three people died, and 1,643 buildings, most of them homes, were destroyed, officials said.
