Overview
- The quake, recorded Monday around 6:29 p.m. PT near the Lahontan State Recreation Area, was revised to about magnitude 5.5 after an initial 5.7 estimate.
- USGS aftershock modeling points to a measurable short‑term risk, with a 17% chance of one or more aftershocks larger than magnitude 5 over the next seven days.
- Dozens of aftershocks followed within minutes, including several between magnitude 2.5 and 3.6, as the ShakeAlert system activated to issue early warnings.
- Shaking was widely felt from Reno and Carson City to Lake Tahoe and Truckee, and early checks showed toppled goods and shattered glass in Fallon but no confirmed major structural damage or injuries.
- Nevada sits in the stretching Basin and Range region, which makes it one of the most quake‑prone U.S. states, so shallow events like this can be felt over long distances and still cause local minor damage.
