In plain English

The two sides move 0.2 to 1 mm a year — 2 to 10 cm every century.

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

The largest earthquake recorded near it was M 6.8 in 1932 (The 1932 Cedar Mountain, Nevada Earthquake) — about 500,000 times the energy of an M3.0, the size people start to feel. It released about 240 kilotons of TNT.

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.
