Assess the likelihood that earthquake hazards will become disasters in San Francisco Bay
the likelihood of an earthquake becoming a disaster in the San Francisco Bay area is reducing, due to the improvement of mitigation strategies and the preparation, education and awareness of the community. In 1906 there were 3000 deaths compared to 1989 where there were only 63 deaths- a decrease of 97.9%.
However, due to the very high HDI area of wealthy properties and commercial buildings the economic damage/losses are still very costly. Furthermore, the surrounding area of soft rock still provides the risk of liquefaction, severe ground shaking and landslides which could all lead to a disaster.
There is a 99.7% chance of another major earthquake in the San Francisco Bay area within the next 30 years, so the risk is prevalent however with mitigation strategies and community preparedness the likelihood of it becoming a disaster is decreasing.
