The USGS reports that residents in Lake and McHenry counties felt the shaking from the 3.6-magnitude earthquake in north-central Illinois Wednesday morning.
The earthquake occurred in Putnam County on the border of LaSalle County, according to the United States Geological Survey (USGS).
The quake, which was at a depth of 2.86 miles, occurred around 4:41 a.m. Wednesday near the town of Standard.
No injuries were reported and no major damage was reported but many residents in the immediate area called 911, according to the Chicago Sun-Times.
At a 3.6 magnitude, the earthquake is considered to be on the weaker end of the scale.
Residents as far away as Lake County and McHenry County reported feeling it.
The USGS said they received reports from Lake County residents in Round Lake, Lake Villa and Mundelein.
The agency also received reports from McHenry County residents in McHenry, Cary, Huntley and Harvard.
The last earthquake reported in Illinois was a 2.9 magnitude quake that occurred near Lake in the Hills in June 2016.
