As Los Angeles recovers from its devastating wildfires, environmental engineers, urban planners and natural disaster experts are casting forward with visions of what could come next for neighborhoods that have been reduced to ash and rubble.

The Hughes Fire has now burned 8,096 acres in Los Angeles and Ventura counties since igniting late Wednesday morning near Castaic Lake, according to Cal Fire. As more than 400 firefighters responded to the scene, an air tanker and four helicopters attacked the blaze from the air, preventing it from jumping Interstate 5, officials said.

Green Day and Billie Eilish performed together, Billy Crystal spoke of the pain of losing his home in the fires, and Joni Mitchell gave a rare performance.

The FireAid benefit concerts will offer aid to LA after wildfires devastated the city. The lineup includes stars like Billie Eilish and Lady Gaga.

The FireAid benefit concerts are tonight, Jan. 30, at both the Kia Forum and Intuit Dome in Los Angeles. The event will raise funds for relief, rebuilding, and fire-prevention efforts in the wake of devastating blazes across the region claimed dozens of lives and thousands of homes.
