Land subsidence outside of Ruler Foods in Belleville, Ill., where an old mine below the store caused the land surrounding the building to sink into the ground on Sept. 26, 2023.
The Illinois Basin is a Paleozoic depositional and structural basin in the United States, centered in and underlying most of the state of Illinois, and extending into southwestern Indiana and western Kentucky. The basin is elongate, extending approximately 400 miles (640 km) northwest-southeast, and 200 miles (320 km) southwest-northeast.
The Illinois Department of Mines and Minerals' Springfield Mine Rescue Station is a historic facility located at 609 Princeton Avenue in Springfield, Illinois.Built in 1910–11, it was the first dedicated state-run institution in the United States established to prevent and respond to mining disasters.
Subsidence frequently causes major problems in karst terrains, where dissolution of limestone by fluid flow in the subsurface creates voids (i.e., caves).If the roof of a void becomes too weak, it can collapse and the overlying rock and earth will fall into the space, causing subsidence at the surface.
“It’s messing with our lives in a big way,” said a neighbor who lives behind the Ruler Foods store.

Precambrian rocks of Illinois are highly faulted; tectonic extension and related thermal subsidence have led to the formation of two major sedimentary basins. These basins, termed the Illinois Basin and Michigan Basin , allowed for extensive deposition of sedimentary rock during the Palaeozoic Era. [ 2 ]
Tectonic subsidence is the sinking of the Earth's crust on a large scale, relative to crustal-scale features or the geoid. [1] The movement of crustal plates and accommodation spaces produced by faulting [2] brought about subsidence on a large scale in a variety of environments, including passive margins, aulacogens, fore-arc basins, foreland basins, intercontinental basins and pull-apart basins.
