Fault · Wyoming
Eagle Bay fault
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.
USGS maps it as 3 sections: middle section, northern section, southern section.
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.

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.
