There are thousands of earthquakes each year that are too small for anyone to feel. "There might be tens to over one hundred earthquakes over a year in Nevada and eastern California that are large enough to be felt. On average an earthquake that is strong enough to be damaging, if it strikes a populated area, occurs about every three years in this region. "
See map showing relative size and location of quakes from 1850s to 1998.http://www.seismo.unr.edu/htdocs/nv-eq.html
Average magnitude would be less than 4.
