USGS On-line Resources For Education Standards in California This website links selected USGS on-line resources to an established list of Science and History-Social Science content standards for California. Selected other science agencies and USGS collaborative organization web resources are included. The San Andreas Fault In The San Francisco Bay Area, California: A Geology Fieldtrip Guidebook To Selected Stops On Public Lands Bay Area landscape evolution, geology, and ecology are part of the discussions associated with the San Andreas Fault System and the impacts of the Great San Francisco Earthquake of 1906. This guide is in support of the effort of the 1906 Earthquake Centennial Alliance. |

| For a more recent technical summary of the San Andreas Fault in the San Francisco Bay Area, see: The Loma Prieta, California, Earthquake of October 17, 1989 - Geologic Setting and Crustal Structure Edited by Ray E. Wells (2004)The Loma Prieta earthquake of 1989 occurred 17 km beneath the Santa Cruz Mountains in California along a left-stepping restraining bend in the San Andreas fault system. Whereas the earthquake was anticipated by geologist, detailed subsequent geophysical and geologic investigations of provided new insights into the character of the earthquake and the crustal structure in the Loma Prieta region. This report includes chapters on geological and geophysical mapping of the region, and interpretations about the long history of both right-lateral faulting and fault-normal compression, thrusting, and uplift.

3D Geology Tours of National ParksStereographic photography of national park landscapes first became popular in the 1880s. This website freaturing selected national parks contains hundreds of anaglyphic (3D) images of seacliffs, volcanos, caverns, canyons, forests, cactus and other features. Red-and-cyan 3D viewing glasses are required to produce the stereographic effect of these images on the computer screen: http://3dparks.wr.usgs.gov. |

Lifelines and earthquake hazards in the greater Seattle areaSeattle and Puget Sound are earthquake country. In the early 1990s scientists and engineers accepted geologic evidence that great subduction zone earthquakes, of magnitude 8 to 9, repeatedly strike along the Washington coast. Since then, researchers have sought to understand the potential for large-magnitude earthquakes in the Seattle area. The results are sobering. Preliminary measurements show clear evidence that strain is slowly building toward the next earthquake. Like any modern urban area, the greater Seattle area depends on highways, railroads, pipelines, ports, airports, communications, and the electrical power system to sustain its economic life. Many of these critical lifelines lie across the path of faults. A new map shows the relation of lifeline elements to selected earthquake hazards. The map is designed to give citizens, engineers, planners, and decision-makers an overview of lifelines and earthquake hazards in the greater Seattle area. |

Geology and Natural History of the San Francisco Bay AreaThis bulletin (2188) was produced in cooperation with the National Association of Geoscience Teachers - Far Western Section. It contains six field trips to SF Bay region destinations including Santa Cruz and San Mateo coasts, the Marin Headlands, the East Bay Hills, and the southern Santa Clara Valley near Hollister. Trips examine geology, human impacts, landscape features, earthquake faults, landslides, and and natural hazards. Supplemental papers examine the regional climate, population history and growth, mineral resources, archeology, and a guide to existing published resources (on the web and in print) about the physical environment of the central California coastal region. |
