Friday Night's

earthquake here in Reno was the strongest since 1953. At least one expert doesn't rule out the possibility of magnitude 6 sometime down the road.

From the University of Nevada, Reno's website:

Earthquake Severity

Less than 3.5 Generally not felt, but recorded.

3.5-5.4 Often felt, but rarely causes damage.

Under 6.0 At most slight damage to well-designed buildings.
Can cause major damage to poorly constructed buildings
over small regions.

6.1-6.9 Can be destructive in areas up to about 100 kilometers
across where people live.

7.0-7.9 Major earthquake. Can cause serious damage over larger areas.

hundred kilometers across.

There have been 25 "microquakes" since midnight.

A 3.0 hit Reno about an hour ago.
