Where is research being conducted?
This map of the San Andreas Fault System in California shows the location of active and recently completed research areas associated with the 3D/4D mapping project. Project scientists (geologist and geophysicist) are teaming up to intensively study sections of the fault in four locations. North of the San Francisco Bay 3D mapping along the fault zone will focus in the Healdburg 100K Quadrangle region.
A 3D data set is largely completed for the greater San Francisco Bay region. New information, however, will be added to the model data sets as it becomes available.
Active research in the Central San Andreas Fault Zone region is subdivided into three field areas, 1) the "Creeping Section" of the fault between San Juan Bautista and Parkfield, California; 2) the section of the fault in the Carrizo Plain area north of Taft, California; and 3) and intermediate "locked" section of the fault zone between Parkfield and the Carrizo Plain.
Preliminary efforts will be to gather new data in these largely remote areas where information is spare or unavailable. New geophysical data will be collected and existing geologic mapping will be revised based on new palentological, geochronological, and other sources of data.
