A magnitude-6.3 earthquake has hit Illinois in the eastern part of the state, killing at least three people and injuring five others.
The quake struck about 12:15pm (03:15 GMT) and was felt across Illinois, the state’s largest, the National Weather Service said.
The US Geological Survey said a magnitude-5.8 quake was recorded near Springfield, Illinois, at about the same time.
The epicenter was about 500km (310 miles) east of Chicago.
The temblor was felt in the Chicago area as far north as Milwaukee and east to as far south as Minneapolis.
The death toll was expected to rise because there was a “strong likelihood” that more people were hurt, the USGS said.
“There is no reason to believe the death toll will rise as the initial number of fatalities increases,” the US Geological Service said in a statement.
“However, as the number of people injured grows, the number who die is likely to rise.”
The USGS estimated the quake was caused by the fault that runs between Illinois and Michigan, which is about 100km (60 miles) north-east of Chicago, and has been in place since 1923.
The fault, known as the Wessinger fault, was first recorded in 1908.
In some areas, the quake caused landslides and mudslides.
The Associated Press said at least two people died in a fire at a storage facility in Illinois.
“This is a significant event,” said Mike McCracken, a seismologist with the US Army Corps of Engineers.
“The number of injuries is very high, but it’s a very small number compared to what we’ve seen in the past.”
The agency did not provide further details about the extent of damage or the victims.
The city of Springfield, which includes Chicago, is a major hub for construction of roads, bridges and other infrastructure.
A large number of workers were evacuated from the city’s downtown area, where some roads had been blocked by landslides.
It was unclear if anyone else was hurt in the city, according to Reuters news agency.
Illinois Governor Bruce Rauner said his state was still in shock.
“We have lost three people.
We are in shock,” he said.
Mr Rauners statement did not say how many people were killed or how many were injured.
The Illinois Geological Survey recorded the quake at a depth of about 300km (186 miles).
