| | Quake: N. California Earthquake Potential |
 | | The North Coast for the following discussion includes the Hayward and Calaveras fault subsystems that lie north of the metropolitan San Francisco Bay region (Figure 8: segments: H4, H5, H6, H7, C5, C6, C7, and C8). |
 | | North Coast seismicity (upper map, USGS catalog, 1968-1985) and creep localities (lower map). |
 | | Although the 5-6 yr duration of the survey is too brief to be highly exact, this demonstration of a sizable creep rate so near its north end may have important implications for the Calaveras fault subsystem as a whole. |
