Regional Map of Ground Shaking Intensity from the Maacama Earthquake
This scenario earthquake is for a magnitude 6.8 earthquake on the Maacama fault in Sonoma County.
Of the estimates outlined in this report, an event along the Maacama fault seems to have, overall, the lowest damage forecasts. A total of 3,212 dwelling units, which represents only 0.1% of the total Bay Area housing stock, would be deemed uninhabitable.
The damage estimate is highest in San Francisco County, where almost 2,000 uninhabitable units, or 62% of the total Bay Area uninhabitable units during this event, would exist. In Sonoma County, the next hardest hit area during this event, most of the damage would occur to mobile homes; they represent 58% of the total uninhabitable units estimated for that county.
An event along the Maacama fault line would cause the largest numbers of displaced and shelter populations in San Francisco County. Over 61% of the total peak shelter population is expected to be from San Francisco County, while only 25% is expected to be from Sonoma County.
In Sonoma County, 80% of the shelter population is a result of uninhabitable red-tagged dwelling units; in San Francisco County, 81% of the shelter population is a result of uninhabitable yellow-tagged units. Since in San Francisco County 99% of the uninhabitable dwelling units are within multi-family buildings, it appears that individuals that reside within inner city multi-family buildings that are yellow tagged have a high likelihood of going to a shelter in the event of a major earthquake.
