Updated , with the latest earthquake of M2.5 or more within 10 km of the trace: M 2.7, 32 km SE of Bodie, CA.

In plain English

The two sides move less than 0.2 mm a year — under 2 cm a century. Slow faults can still produce large earthquakes, just rarely.

Its most recent surface rupture is younger than 15,000 years.

The largest earthquake recorded near it was M 6.3 in 1934 (The 1934 Excelsior Mountains, Nevada Earthquake) — about 89,000 times the energy of an M3.0, the size people start to feel. It released about 43 kilotons of TNT.

This week vs. its last ten years

quiet

No quakes of M1.5+ within 5 km of the trace in the last 7 days. A normal week: 0–0.

The Huntoon Valley fault system as mapped at the surface (glowing), with the other mapped faults nearby, 167 of the M2.5+ earthquakes within 10 km of it since 2016 (dots) and the epicentres of the large historic earthquakes recorded near it (rings). Traces: USGS Quaternary Fault and Fold Database. Historic epicentres are estimates.

Every year since 2016

Earthquakes of M2.5+ with an epicentre within 10 km of the mapped trace. Near is not the same as on: some will have slipped on neighbouring faults.
