The Las Vegas area averages about 0.5 magnitude 4.0+ earthquakes per year and has recorded 0 earthquakes (M1.0+) within 75 km in the past 30 days.
Las Vegas sits in the moderate category for U.S. seismic activity. The largest earthquake in or near Las Vegas since records began was the magnitude 5.7 Little Skull Mountain earthquake in 1992, which struck approximately 90 km northwest of the city.
According to the U.S. Geological Survey's National Seismic Hazard Model, there is approximately a 12% probability of a magnitude 6.7 or greater earthquake within 100 km of Las Vegas in the next 30 years, and a 5% probability of a magnitude 7.0 or greater event. The largest credible earthquake predicted for the Las Vegas area is a magnitude 6.8 event on the Frenchman Mountain Fault, which lies 15 km from downtown Las Vegas.
