This part of SIM 3261 presents data for faults for the geologic and geomorphic map (see sheet 10, SIM 3261) of the Offshore of Carpinteria map area, California. The vector data file is included in "Faults_OffshoreCarpinteria.zip," which is accessible from https://pubs.usgs.gov/ds/781/OffshoreCarpinteria/data_catalog_OffshoreCarpinteria.html.
This map area lies within the Western Transverse Ranges geologic province, which is north of the California Continental Borderland (Fisher and others, 2009). This province has undergone significant north-south compression since the Miocene, and recent GPS data suggest north-south shortening of about 6 to 10 mm/yr (Larson and Webb, 1992; Donnellan and others, 1993). The active, east-west-striking, north-dipping Pitas Point Fault (a broad zone that includes south-dipping reverse faults), Red Mountain Fault, and Rincon Creek Fault are some of the structures on which this shortening occurs (see, for example, Jackson and Yeats, 1982; Sorlien and others, 2000; Fisher and others, 2009). This fault system, in aggregate, extends for about 100 km through the Ventura and Santa Barbara Basins and represents an important earthquake hazard (see, for example, Fisher and others, 2009).

To expand geologic mapping to the seafloor within California's State
Waters, to update coastal geologic mapping, and to contribute to a
uniform regional geologic database. Additionally, to provide a geologic
map for the public and geoscience community to aid in assessments and
mitigation of geologic hazards in the Santa Barbara coastal plain region
and to provide sufficient geologic information for land-use and
land-management decisions both onshore and offshore.
Map political location: Santa Barbara and Ventura Counties, California

Base maps used are hillshades generated from IfSAR, LiDAR, and multibeam
mapping both onshore and offshore (see sheets 1 and 2, SIM 3261, for more information).

Map elements were visually checked for overshoots,
undershoots, duplicate features, and other errors by the
lead authors and by the GIS technician(s) who created the digital database.
Review drafts of the map were reviewed internally by at least two other geologists for consistency
with basic geologic principles and general conformity to USGS mapping
standards.
Data are complete: no offshore features that could be accurately identified and
represented at the compilation scale of 1:24,000 were eliminated or
generalized. The smallest area represented is approximately 100 square
meters. All geospatial database elements are attributed.
Faults were primarily mapped by interpretation of seismic reflection profile data (see sheet 8, SIM 3261).
Faults lines were digitized by heads-up screen digitization on to shot-point picks from seismic-
line navigation data - each shot point has an associated lat/long in the survey data. Error is introduced
from layback, as well as from interpretation of oblique features, so horizontal accuracy of fault and fold
location is estimated to be on the order of 10 to 20 meters.
