The Wabash Valley seismic zone consists largely of vertically oriented ("normal") faults deeply buried under layers of sediment. Although the tectonics of the region are not fully understood and are the subject of ongoing research, these faults are thought by some to be associated with a branch of the New Madrid aulacogen, an old rift zone where the lithosphere actively began to pull apart at ...
Situated in a stable continental region of the Midwestern United States, the Wabash Valley seismic zone (WVSZ) is an area of dispersed seismic activity that encompasses the border areas of Illinois, Indiana, and Kentucky.
The fault, which is aligned east–west, is connected to the north–south-trending Wabash Valley Fault System at its eastern end. [15] Seismographic mapping completed by geologists revealed monoclines , anticlines , and synclines , all of which suggest deformation during the Paleozoic era , when strike-slip faulting took place nearby.

In 2008 in the nearby Wabash Valley seismic zone, a similar magnitude 5.4 earthquake occurred with its epicenter in Illinois near West Salem and Mount Carmel. Instruments were installed in and around the area in 1974 to closely monitor seismic activity. Since then, more than 4,000 earthquakes have been recorded, most of which were too small to ...
The Wabash River, shown within its drainage basin. The Wabash Valley is a region located in sections of both Illinois and Indiana.It is named for the Wabash River and, as the name is typically used, spans the middle to the middle-lower portion of the river's valley and is centered at Terre Haute, Indiana.
In 1971, the race took place at the Wabash Valley Fairgrounds on the Action Track, a half-mile oval dirt track. It consisted of a 50-mile, 100- lap test of endurance and speed. Activities included midget-races, skydiving, arts and crafts, entertainment, and full-fledged carnival with rides.
Mount Carmel is 5 miles (8.0 km) northeast of the Forest of the Wabash, a National Natural Landmark within Beall Woods State Park and about a mile north-northeast of one of its main employers, the Gibson Generating Station. Mount Carmel is also the home of Wabash Valley College, part of the Community College System of Eastern Illinois. Some ...
The facility is part of 240 acres (0.97 km 2) that comprise the Wabash Valley Family Sports Center just east of the Terre Haute International Airport. The course itself is built on a reclaimed coal mine and consists of an external loop of 3 km and four internal loops that allow for circuits of varying lengths.
