Explosion at a California fireworks warehouse sets off massive blaze and forces evacuations

An explosion at a fireworks warehouse in rural Northern California caused a massive fire, sending thick plumes of black smoke into the air and forcing evacuations, authorities said. There were no immediate reports of injuries.

People were urged to avoid the area for several days following the Tuesday night blast, which set off a barrage of fireworks and caused a huge blaze that led to other spot fires and collapsed the building near Esparto. The farming community is about 40 miles (64 kilometers) northwest of Sacramento.

“The fire will take time to cool, and once it does, explosive experts must safely enter the site to assess and secure the area,” the Yolo County Sheriff’s Office said in a news release.

The cause of the explosion was under investigation, the sheriff’s office said.

The fire was held at nearly 80 acres (33 hectares) as of Wednesday morning after scorching surrounding agricultural fields, the California Department of Forestry and Fire Protection said.

“We do believe this location is owned by an active pyrotechnic license holder,” Deputy State Fire Marshal Kara Garrett told KXTV in Sacramento. She added: “This type of incident is very rare, as facilities like this are required to not only follow our stringent California pyrotechnic requirements, but also federal explosive storage requirements.”

Gov. Gavin Newsom’s office said it was tracking what happened and that state ground and air resources were deployed.

“The State Fire Marshal has sent an arson and bomb investigation team, and stands ready to provide additional support as needed,” the governor’s office said on the social site X.
