Like much of the state of California which it is based on, San Andreas suffers occasional earthquakes. One of these earthquakes took place a short time before the events of the game Grand Theft Auto: San Andreas. The earthquake is mentioned in the news on several radio stations. It is the cause of the closures of the inter-county bridges at the start of the game. No earthquakes ever occur during gameplay.
In 1988, an earthquake devastated the Doherty area in San Fierro. Several blocks were leveled and buildings were destroyed. Most of the area had been reconstructed but some damaged structures still remain.
