Central Nevada Seismic Belt
Nevada, USA · continental rift · 1216.3 km of mapped active fault in 11 traces
unknown as of 7 November 2026.
no baseline good enough to compare against; the catalogue holds too few events on this system to say what normal is

What this system normally does
From 1995 to 2025 the catalogue holds 1 earthquakes of M4.5 or larger attributable to this system: about 0.03 a year. That figure is what "elevated" on this page is measured against.
Confidence in that rate is low: the catalogue holds too few events here for the average to carry much weight, and this system is never called elevated on the strength of it alone.
