Earthquake Hits Illinois, Registers 3.4 Magnitude

ILLINOIS — A 3.4 magnitude earthquake hit Illinois early Monday, the U.S. Geological Survey (USGS) confirmed.

The earthquake hit at 2:53 a.m.

Just after 3 a.m., the DeKalb County Sheriff's Office took to Facebook to inform residents, saying, "Information for those who were woken up a short time ago to your house shaking, there was just a 3.4 magnitude earthquake northwest of Somonauk."

Police in Plano, in nearby Kendall County, also notified residents who may have felt the rumbling.

"If you heard or felt anything, this is what it was," police said on social media. "We are not aware of any damage or injuries in our town. People are reporting feeling the quake from Plainfield to Rochelle."

On Facebook, residents of neighboring communities including Aurora, Oswego and Sandwich also reported feeling the earthquake and hearing a loud boom. "Thought a car hit the side of my house," one resident wrote, while another said, "I thought a tree fell!" Others said they thought it was particularly loud thunder, given Sunday night's storms.

Somonauk Police Chief William King said there were no reports of injuries or property damage, Fox 32 Chicago reported.

The USGS said more than 200 people reported feeling the earthquake. Those who did can share their experience online with the USGS.
