Northern Illinois Experiences Magnitude 4.3 Earthquake



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:

  • 6 km (4 miles) WNW (292°) from Virgil, IL
  • 8 km (5 miles) E (94°) from Sycamore, IL
  • 8 km (5 miles) N (1°) from Maple Park, IL
  • 14 km (8 miles) ENE (67°) from DeKalb, IL
  • 35 km (22 miles) NW (315°) from Aurora, IL
  • 77 km (48 miles) WNW (282°) from Chicago, IL

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 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.
