Detailed Description
A. Building area outlines for the San Francisco Bay region. The model boundary is also shown, which is coincident with a detailed 3D geologic model of the Bay Area (Aagaard et al., 2010, 2020).
B. The mass of buildings is summed within 1 km2 areas, and its distribution is shown on the surface. An equivalent water thickness (load change) scale in m is also given for comparison with seasonal loading.
C. A finite element model is shown gridded into 1 km cubes (the model boundary is shown in A). Young's modulus (elastic stiffness) variations are shown projected on the surface topography but which also vary throughout the model volume.
