  11. Title: Relative Liquefaction Susceptibility of Monterey County, California, 2001

    Contributors:

    Summary: This polygon shapefile contains areas of relative liquefaction suceptability in Monterey County, California. A common type of ground failure associated with moderate and large earthquakes is liquefaction in which water-saturated fine-grained cohesionless sediments lose strength and may fail during strong ground shaking. Liquefaction susceptibility depends on the age and type of material, relative density of the material, and the depth to first (shallowest) water. Generally, younger sediments (especially latest Holocene that are less than 1,000 years old) such as loose fill, river channel, and flood plain deposits are more likely to liquefy than older Pleistocene terrace deposits. Relative liquefaction susceptibility was evaluated using a simplified version of the methodology developed for the Monterey Bay area by the USGS (Dupré and Tinsley, 1980; Dupré, 1990; Pike and others, 1994). The resulting data set shows that the areas of highest susceptibility include the Salinas, Carmel, San Antonio, and Peachtree Valleys. This layer is part of a collection describing Geology resources and constraints Monterey County, California. This map depicts the relative liquefaction susceptibility of sediments in Monterey County. The purpose of this map is to provide a comparison of relative liquefaction susceptibility for regional planning studies in Monterey County. Rosenberg, Lewis I. (2001).

  15. Title: Paleontological Resources of Monterey County, California, 2001

    Contributors:

    Summary: This point shapefile depicts paleontological resources within Monterey County, California. Fossils provide important evidence to help determine what happened in Earth history and when it happened. Today the animals and plants that live in the ocean are very different from those that live on land, and the animals and plants that live in one part of the ocean or on one part of the land are very different from those in other parts. Similarly, fossil animals and plants from different environments are different. It becomes a challenge to recognize rocks of the same age when one rock was deposited on land and another was deposited in the deep ocean. Scientists must study the fossils from a variety of environments to build a complete picture of the animals and plants that were living at a particular time in the past (Edwards and Pojeta, 1999). Because fossils are so useful to science, they need to be considered a resource and properly managed. The purpose of this database is to provide information on the type of fossil and the location so that these fossils may be preserved for science. Rosenberg, Lewis, I. and Clark, Joseph C. (2001).

  17. Title: Digital Geologic Map of Monterey County, California, 1934-2001

    Contributors:

    Summary: This poygon shapefile contains a geologic model of Monterey County, California. For geologic and seismic hazard evaluation, the most important factor is the geologic model. In this study, the geologic model is a digital compilation of stratigraphic formations and faults in Monterey County. T.W. Dibblee, Jr. mapped most of the geology in Monterey County for the U.S. Geological Survey in the 1960s and 1970s. Other major contributors of mapping include J.C. Tinsley, III, W.R. Dupré, V.M. Seiders, D.C. Ross, J.C. Clark, and C.A. Hall. To provide a logical framework for the many geologic units in Monterey County, T.W. Dibblee, Jr. prepared a countywide correlation of map units, with emphasis on the Tertiary and Cretaceous age sedimentary rocks. Cretaceous plutonic and metamorphic rocks follow the nomenclature of Ross (1972, 1976). Quaternary deposits are classified based on the work of Tinsley and Dupré. This data set presents a unified, seamless geologic coverage for the seventy-nine 1:24,000 scale quadrangles that cover Monterey County. This layer is part of a collection describing Geology resources and constraints Monterey County, California. The purpose of this map is to provide a seamless, regionally consistent geologic database for regional planning studies in Monterey County. Rosenberg, Lewis, I. (2001).

    Contributors:

    Summary: This point shapefile contains records of historical seismicity (1931-2001) recorded by the Northern California Earthquake Data Center. These data show clustered earthquakes along many of the faults in Monterey County. The largest concentration of events is along the San Andreas fault. Other faults with clustered seismicity include the San Gregorio fault zone (Rocky Creek segment), the Reliz fault, and the Nacimeinto fault. This layer is part of a collection describing Geology resources and constraints Monterey County, California. Epicenters occurring from 1931 to April 2001 with magnitudes of 3 or greater are plotted to provide a perspective on the historical seismicity of Monterey County. Rosenberg, Lewis, I. (2001).

  20. Title: Faults of Monterey County, California, 2001

    Contributors:

    Summary: This line shapefile depicts the relative activity of faults in Monterey County, California. Fault rupture is a seismic hazard that affects structures sited above or nearby an active fault (fault showing movement within the past 11,000 years). The only known historically active fault in Monterey County is the San Andreas fault, which ruptured during the 1966 Parkfield earthquake. The State of California has not zoned other faults within Monterey County as active; however, other studies document Holocene activity on local faults. These include the offshore parts of the Navy and Chupines faults (McCulloch and Greene, 1989); the Tularcitos, Sylvan thrust, Hatton Canyon (Rosenberg and Clark, 1994); the Garrapata/Palo Colorado and Rocky Creek fault segments of the southern San Gregorio fault zone (Clark and Rosenberg, 1999); the San Gregorio fault offshore of Point Sur (Eittreim and others, 1998), and the Zayante/Vergeles fault (Coppersmith, 1979). Other faults such as the Reliz/Rinconada, the Sur fault zone, the Laureles, the Cachagua, and the Miller Creek faults show indications of late Pleistocene activity (750,000 to 11,000 years before present). Detailed work on these faults may show that they are more recently active than currently known. Most of the faults in Monterey County are classified as pre-Quaternary (latest movement more than 1,600,000 years before present). This classification is a result of a lack of information, rather than conclusive evidence as to the timing of fault movement because the majority of geologic mapping did not focus on the activity assessment of faults. Faults classified as pre-Quaternary should not necessarily be regarded as inactive. This layer is part of a collection describing Geology resources and constraints Monterey County, California. The purposes of this data set are to show the location of faults and to provide a comparison of relative fault rupture hazard for regional planning studies in Monterey County. This map does not take the place of fault-rupture hazard zones designated by the California State Geologist (Hart and Bryant, 1999). Rosenberg, Lewis I. (2001).
