strain and therefore undiscovered faults might exist. This task will guide reconnaissance field
work of known and suspected regional Quaternary faults (Fig. 5). The locations, extent, sense of
displacement, paleoseismic activity, and/or slip rate activity of regional faults are needed for an
accurate understanding of faults in the Las Vegas Valley. Regional faults can also have
earthquakes that can cause damaging ground motion in Las Vegas basin and are worth
investigating on that basis alone. There are currently about a dozen regional faults that would be
included in this task (Fig. 5).
Task 2 has seven subtasks:
Task 2.1 - Unrecognized Fault Investigation,
Task 2.2 -Predevelopment Digital Elevation Model along Faults,
Task 2.3 -Evaluation of Potential Buried/Blind Faults within Las Vegas Basin,
Task 2.4 -Evaluation of Hydro-Compaction as a Source of Deformation,
Task 2.5 -Regional Faults Investigation,
Task 2.6 -Development of a Tectonic and Deformation Model,
Task 2.7 - Fault Map and Reporting.
These tasks will be conducted within the first three years of the project so that the seismic
sources are developed for the final analysis of earthquake hazard.
