redwood city liquefaction map

Redwood City is rich in history, from its earliest inhabitation by the Ohlone people, to its tradition as a port for lumber and other goods, to its place as the county seat of San Mateo County. Today the city is known as the home of several technology companies such as Oracle and Electronic Arts.

Figure on the right (USGS photo) shows part of the Cypress structure, the freeway approach to the Bay Bridge from Oakland, which collapsed during the Loma Prieta earthquake, killing 42 people. These maps are the result of over a decade of work and collaboration between geologists from the consulting firm Many of the region’s utilities and lifeline owners have made use of an Figure on the right (USGS photo) shows part of the Cypress structure, the freeway approach to the Bay Bridge from Oakland, which collapsed during the Loma Prieta earthquake, killing 42 people. Such areas along the Bay margins are found in San Francisco, Oakland and Alameda Island, as well as other places around San Francisco Bay. As of the 2010 census, the city had a total population of 76,815. These maps are the result of over a decade of work and collaboration between geologists from the consulting firm Many of the region’s utilities and lifeline owners have made use of an These maps are designed to give the general public as well as land-use planners, utilities and lifeline owners, and emergency response officials, new and better tools to assess their risk from earthquake damage.

Most residents of the Bay Area live and work in these low-lying areas that are underlain by these young deposits. When the ground liquefies, it may lose its ability to support buildings and other structures. Bay mud remains a seismic hazard because on the basis of its past performance in earthquakes it will produce stronger levels of shaking than other geologic units.The new maps show in unprecedented detail the nature of the materials that underlie areas of densest urban development and highlight areas that may be prone to shaking-related damage during future earthquakes. The older map also shows locations of liquefaction observed in historical earthquakes, particularly the In addition, the California Geological Survey has zoned the greater San Francisco area for liquefaction hazard in their We can expect history to repeat itself in the next big Bay Area earthquake.The highest hazard areas shown by the liquefaction hazard maps are concentrated in regions of man-made landfill, especially fill that was placed many decades ago in areas that were once submerged bay floor.

Liquefaction during large earthquakes commonly disrupts pipelines and road networks and also may cause buildings to settle and move downslope or toward stream banks.These new maps cover the San Francisco Bay region (outlined in red).

Other potentially hazardous areas include those along some of the larger streams, which produce the loose young soils that are particularly susceptible to liquefaction.These new maps show a lower likelihood of liquefaction than previously thought in regions underlain by Bay mud that fringes many parts of San Francisco Bay.
