Earthquakes in Clinton County, Illinois
Too few earthquakes here to say what is "normal"
Only 29 earthquakes of M1.5 or largerhave 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 So we do not publish one.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 Clinton County, Illinois, not about our data: it is a quiet place. There have been none of M1.5 or larger in the last 7 days.
