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 6.3 in 1902 (Near Pine Valley, Utah) — about 100,000 times the energy of an M3.0, the size people start to feel. It released about 49 kilotons of TNT.

USGS maps it as 6 sections: Anderson Junction section, Ash Creek section, Cedar City section, Shivwitz section, Whitmore Canyon section, southern section.

The Hurricane fault as mapped at the surface (glowing), with the other mapped faults nearby, 15 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.
