SANTA CRUZ, Calif. — Three new sets of maps detail the offshore bathymetry, habitats, geology and submarine environment of the seafloor off the coast of San Francisco, Drakes Bay, and Tomales Point.Critical for resource managers, the maps are part of the California Seafloor and Coastal Mapping Program, a series of maps published by the U.S. Geological Survey with support from the California.

San Francisco Peaks Geology. By Bill Wade – a geologist and a 12-year member of Flagstaff’s USFS/NPS Interpretive Partnership. Introduction: The San Francisco Peaks are the eroded remains of a single, once-much-higher, stratovolcano called San Francisco Mountain (‘SFM’).Stratovolcanoes are large conical volcanoes composed of many alternating layers of hardened lava, and looser tephra.
The 1906 San Andreas fault event was preceded from 1881 to 1903 by 18 earthquakes of M ≥5.5 and was followed by quiescence, with only three earthquakes of M ≥5.5 until 1954. First known map of San Francisco Bay Area by Fray Juan Crespi in 1772. Map nerds rejoice—we've combed archives for old maps of San Francisco that cover everything from fire damage to failed. A geologic map is one of the basic tools to understand the geology, geologic hazards, and geologic history of a region.With heightened public awareness about earthquake hazards leading up to the 100th anniversary of the 1906 San Francisco earthquake, the U.S. Geological Survey (USGS) is releasing new maps of the San Francisco Bay Area designed.
The 1906 earthquake left 225,000 of San Francisco’s 400,000 citizens homeless. At the time of the earthquake, much of the Bay Area was sparsely populated; San Jose was a small town of 25,000. Today, the Bay Area population has increased ten-fold to 7 million people, all at risk from expected earthquakes on one or more of the Bay Area faults. The older map also shows locations of liquefaction observed in historical earthquakes, particularly the Great 1906 earthquake and the 1989 Loma Prieta quake. In addition, the California Geological Survey has zoned the greater San Francisco area for liquefaction hazard in their seismic hazard maps.
