SF Bay Liquefaction Susceptibility Map

inspired by US Geological Survey’s San Francisco Bay Liquefaction Susceptibility Map

~25% of the San Francisco Bay region may be exposed to liquefaction with the shaking that has been forecasted. Some of the most hazardous areas are beneath our urban core.  What is the grade of the land you and your loved tread?

New maps show the distribution of rock and sediment having different vulnerabilities to liquefaction when shaken by earthquakes, together with explanation of the process and examples of its effects.
