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.

It has broken the ground surface within the last 150 years.

The largest earthquake recorded near it was M 7.1 in 1954 (The 1954 Fairview Peak, Nevada Earthquake) — about 1,400,000 times the energy of an M3.0, the size people start to feel. It released about 670 kilotons of TNT.

This week vs. its last ten years

Too quiet to rank: fewer than half a year's worth of weeks with any M1.5+ quake within 5 km, in ten years. A single quake here would read as "unusual", so we do not score it.
