![]() I believe its a story of two halves, between the Northern and Southern hemispheres and the action runs along the Southern flank of the Eurasian plate and the two plates to the west, being the bigger North American plate and the much smaller Caribbean plate on its Southern flank. That said, that's enough to establish a picture as to the overall trend of movements that's happening globally. I'm fortunate in that I gather screenshots of movements and normally just keep 2 years worth so as to save memory in my tablet. It generally takes a quake of 2.0 or more to be noticed by people.Įventide It's easy to get buried in a mountain of detail when trying to expand upon the movement ot Earth's tectonic plates, so I'll try by best not to do just that. Onshore, Ohio DNR data shows three small inland quakes of 1.0 to 1.5 already in 2022 epicentered in Trumbull, Ashtabula and Tuscarawas counties. The largest was a 5.0 quake that struck Lake County on Jan. More than 300 earthquakes of 2.0 magnitude or greater with epicenters in the state have occurred since 1776, according to Ohio DNR. Minor seismic activity is fairly common in northeast Ohio, which sits atop ancient fault lines in subsurface Precambrian Age rock. Ohio has more seismic monitors in the area than USGS, which lists seven offshore quakes in Lake Erie thus far this year. "It could be the activity is just migrating along the fault, or it could be remnant aftershock activity from that larger earthquake two years ago." "All these earthquakes are happening right in the same spot, so we're pretty sure they're on the same fault," Fox told WKYC in Ohio. Fox speculated the recent cluster may be aftershocks. Ohio DNR seismologist Jeff Fox said quakes are occurring along a fault that produced a larger, 4.0 magnitude quake in June 2019 which was felt as far away as Michigan. The most recent quake was a 2.4 magnitude on Feb. Quake depths range from 2.1 to 7.4 kilometers under the surface. They range from 1.3 to 3.0 in magnitude and some are being felt locally on shore. The quake epicenters are clustered about two miles offshore of Lake County east of Cleveland. Geological Survey (USGS), tracks seismic activity in the region. ![]() Nine weak, shallow earthquakes have already struck central Lake Erie in the first weeks of 2022, according to the Ohio Department of Natural Resources, which, alongside the U.S. The Earth is trembling underneath Lake Erie. Nine small earthquakes have shaken Lake Erie off Lake County, Ohio, in the first six weeks of 2022, according to Ohio Department of Natural Resources seismic monitoring.
