This was a minor earthquake. Quakes this small are rarely felt and do not cause damage.
At this magnitude and depth, people at rest would likely notice it out to about 24 km (15 mi) from the epicentre. In North Madison, 7 km away, the estimate is intensity II (weak). Estimated from magnitude, depth and distance with the intensity equation USGS Did You Feel It? uses; felt reports, where there are any, are the measurement.
Likely felt in: Madison 9 km, intensity II · Painesville 13 km, intensity II. Estimated for each town centre; each link is that town's own record.
How big was it?
This earthquake released about 30 lb of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 3.0 would have released about 32 times as much.
- Mineral, Virginia 2011 M 5.8 500,000× the energy of this one
- Magna, Utah 2020 M 5.7 350,000× the energy of this one
- Around the size people start to feel M 3.0 32× the energy of this one
- This earthquake M 2.0 about 30 lb of TNT
Energy from the Gutenberg–Richter relation (log10E = 1.5M + 4.8), rounded to two figures; bar length is magnitude, which is already a logarithm of energy. Magnitudes of past earthquakes from the USGS catalogue.
For this area
The largest earthquake within 50 km since 2016 was M 4.0 on 2019-06-10 — about 1,000 times the energy of this one.
Before 2016, the USGS record lists one earthquake of M5 or more within 50 km:
