In the first six weeks of 2022, seven earthquakes were recorded in the eastern basin of Lake Erie. Over 200 earthquakes have been recorded since 1776 in Ohio, mostly around Lake Erie.
Seismic activity rarely exceeds 3.5 magnitude, but there have been a few earthquakes that have eclipsed 4.0. In 2019, for example, the Ohio Department of Natural Resources detected a 4.2 magnitude earthquake off Lake Erie. It was the 5th earthquake to break 4.0 in Ohio since 1986.
Scientists are working on figuring out why. Read the full story here.
