Earthquakes in Slope County, North Dakota
Too few earthquakes here to say what is "normal"
Only 1 earthquake of M1.5 or largerhas been recorded within 100 km in the 10 years of record we hold, and most weeks have none. A QuakeIndex score is a percentile against this place's own weeks — and when almost every week is empty, that number would just be reporting whether anything happened at all, dressed up as a percentile. So we do not publish one.
This is a statement about Slope County, North Dakota, not about our data: it is a quiet place. There have been none of M1.5 or larger in the last 7 days.
