The uncertainties in the estimates of the loss from individual earthquakes is at least a factor of 3-4, and may be as high as a factor of ten. In spite of this, it should be emphasized that the report uses a national methodology that can be regarded as the best available. The uncertainties can be reduced by more research. Specifically, more research can help to characterize the earthquake hazards that face Nevada much more precisely than what is presently known. Research can include mapping faults, characterizing the ground motion that will affect structures including complications caused by local soil conditions, and improved understanding of the locations and rates of earthquakes.
Some research is ongoing.
The FEMA report confirms that it has been an appropriate decision on the part of the USGS to support this network and other research projects. It also confirms the importance of continuing and hopefully expanding that support. Everyone in Nevada will benefit if Congress approves and fully funds continuation of the National Earthquake Hazard Reduction Program. Las Vegas has never been a priority for seismic monitoring, either with Nevada or Federal support. It is our hope that this will change in the near future.
