The Oakland Firestorm of 1991 was a large urban fire that occurred on the hillsides of northern Oakland, California and southeastern Berkeley on Sunday October 20, 1991, almost two years after the Loma Prieta earthquake. The fire has also been called the Oakland hills firestorm, the East Bay Hills Fire, and the Tunnel Fire (because of its origin above the west portal of the Caldecott Tunnel) in Oakland. The fire ultimately killed 25 people and injured 150 others. The 1,520 acres (6.2 km²) destroyed included 3,354 single-family dwellings and 437 apartment and condominium units. The economic loss has been estimated at $1.5 billion.
