200th Anniversary of the 1811-1812 New Madrid Earthquakes - Second Major Earthquake
On January 23, 1812 an earthquake of magnitude in the mid-7s occurred at 9:15 am in the New Madrid, Missouri area. This earthquake was slightly less than the Dec 16th earthquake that was located on the southernmost fault and was 5 weeks previous. The January earthquake is believed to be associated with the northern most of the 3 New Madrid faults and would have caused nearly as extensive damage as the December 16th event. This second major earthquake was followed by a week of aftershocks of 1 in the 6s, 11 in the 5s and 78 in the 4s.

ISGS-Led Consortium Begins Injection of CO2 for
storage at the Illinois Basin - Decatur Project
The Midwest Geological Sequestration Consortium (MGSC) has begun
injecting carbon dioxide (CO2) for the first million-tonne
demonstration of carbon sequestration in the U.S. The CO2 will
be stored permanently in the Mt. Simon Sandstone more than a mile beneath
the Illinois surface at Decatur. The MGSC is led by the Illinois State
Geological Survey (ISGS), part of the Prairie Research Institute at the
University of Illinois.
