The two biggest fires devastating the Los Angeles area grew just slightly as firefighters beat back the blazes that have killed at least 10 people, obliterated neighborhoods and left the nation’s second-largest city on edge.

Officials say the two biggest wildfires ravaging the Los Angeles area this week have burned at least 10,000 homes, buildings and other structures.

Authorities say a burning truck’s fuel tank exploded while Los Angeles firefighters were trying to battle the blaze.

When rainstorms like this week’s powerful atmospheric river hit California, the earth begins to move.
