Early this morning Illinois was rocked with with a Magnitude 4.3 Earthquake at aprox 3:59 am on February 10th 2010.
Depth: 5 km (3.1 miles) set by location program
Distances:
The USGS estimates that several million earthquakes occur in the world each year, but many go undetected because they occur in remote areas or have very small magnitudes. The USGS now locates about 50 earthquakes each day; 20,000 a year. For more details about the earthquake click on the link below.
The USGS is working to improve its earthquake monitoring and reporting capabilities through the Advanced National Seismic System (ANSS). In the past three years the USGS has installed approximately 300 new earthquake monitoring instruments in the San Francisco, Seattle, Salt Lake City, Anchorage, Reno, Las Vegas, and Memphis areas. Full implementation of ANSS will result in 6000 new instruments on the ground and in structures in at-risk urban areas, as well as a backbone of modern seismic instruments for the entire Nation. Once in place, the ANSS will provide emergency response personnel with real-time (within 5-10 minutes of an event) information on the intensity and distribution of ground shaking that can be used to guide emergency response efforts. Similarly, information on building “shaking” will equip engineers with the data they need to improve building designs in the future.

I felt it! My house shook and it woke me up.
It woke me up. The bed was shaking and the TV was moving around on the table. I had no idea what happened and never expected an earthquake in Naperville.
First there was rumbling, then we had a good shake, finished off with a jolt! Only lasted a few seconds but nice shaker! I felt like I was back in Portland!
Felt it in north naperville. I88 and Rt. 59. Shook my house and woke me up out of deep sleep. Really strange feeling
I felt it too!
My house shook!
omg!
It was scary we just woke up suddenly! we’re just 10 I mean. It was making our house viberate! Our house was shaking……….. really scary!
I felt a shake and a lesser shake seconds later. I live in Naperville.
I thought the house might collapse.
My house shook quite a bit. This definitely felt bigger than a 5.6 I experienced in SanFran some years ago
I felt the whole house was shaking and it woke me up.
North Naperville Resident Also - so did I! A big boom woke me up at 4am this morning. Scared the hell out of me. Had no idea it was an earthquake -
It was for short duration but really woke me .
I was awakened by a large boom and my bedside lamp was rocking back and forth, ready to fall over. I remember grabbing the lamp.
My son said it felt like a meteor hit somewhere and the shaking lasted 5 seconds.
We have the BNSF railroad lines right behind our house so I thought it was a train but my son said no train was going through at the time.
i woke up at about 4:02 and still felt it!
I thought my fridge fell over! My first ever earthquake experience…
