It can be felt hundreds of miles, even if it was a smaller earthquake. The Wabash Valley Seismic Zone (also known as the Wabash Valley Fault System or Zone) is a tectonic region located in the Midwest of the United States, centered on the valley of the Lower Wabash River, along the state line between southeastern Illinois and southwestern Indiana. The November 9, 1968 Wabash Valley Zone magnitude 5.5, was the strongest in the central U.S. since the October 31, 1895 New Madrid Zone quake, centered near Charleston, Missouri. Red circles indicate earthquakes that Deformation of the land surface directly over a fault that moves may manifest as very localized uplift or subsidence, or lateral distortions of up to several meters (for a very large earthquake). Earthquake activity in the Wabash Seismic Zone has a history of affecting the St. Charles and the St. Louis metropolitan area and its residents. in the New Madrid seismic zone.”. Ones strong enough to be felt usually happen once or twice a year, and those large enough to cause moderate damage have occurred every decade or so. Enhancement of short-wavelength magnetic anomalies reveal numerous NW- to NNE-trending ultramafic dikes and six intrusive complexes (including those at Hicks Dome and Omaha Dome). is the threat? what is the chance that the shaking they cause will be damaging? Present-day GPS measurements show that the region deforms at about 1–2 mm/yr with compression along the Wabash Valley Fault Zone, and extension in SW Indiana. Louis was here at the time, and all that happened was some chimneys fell in East St. Louis. The initial earthquake was felt in parts of 16 states. Studying earthquakes is especially challenging because they happen infrequently The concern of Douglas Wiens, Ph.D., and Michael Wysession, Ph.D., seismologists at Washington University in St. Louis, is that the New Madrid Fault may have seen its day and the Wabash Fault is the new kid on the block. “As the continents bang into each other, sometimes they pull apart, and the crust cracks and ruptures, causing, earthquakes, “ he explained. Both the interpreted dike pattern and mapped Wabash Valley Fault System terminate near the Reelfoot-Rough Creek-Rome rift system. The best writers in science tackle science's hottest topics. Chapter6! of the Internal Revenue Code that's At Science 2.0, scientists are the journalists, and withoutany advanced warning. “. Vernon and West Franklin in Posey County, in an area that is known as the Wabash Valley Seismic Zone. h޼XkS�8�+��d-��a�t� �fR����v��/�nH��m����خR:��8z]�q�=GR��B donation today and 100 percent of your Please donate so science experts can write .

This fault system is about 90 km long and 50 km wide in southeastern Illinois, southwestern Indiana, and northwestern Kentucky near the deepest part of the Illinois Basin (fig.

“These are changes we can measure with instruments, but we can’t sense them as humans,” he said.

To the surprise of many, originated in the Wabash Valley Fault, not the better-known and more-dreaded New Madrid Fault in Missouri’s boot heel.

After a major earthquake in the New Madrid or Wabash Valley seismic zone, what changes to the landscape would we most likely see?

The cracks in the sidewalk are the fault lines, and the rest of the sidewalk represents tectonic plates. [4], According to the United States Geological Survey, lesser earthquakes occur relatively frequently, but those at a magnitude less than 3.5 or so are usually not felt. Also, the processes that cause earthquakes work over many thousands of years and deep beneath the Earth’s surface.

Nonetheless, research The Wabash Valley Seismic Zone consists largely of vertically oriented ("normal") faults deeply buried under layers of sediment. The crust got stretched and thinned. You could not be signed in.

“. We are a nonprofit science journalism the region has been mounting since the late 1970s. [5], The concern of seismologists Douglas Wiens and Michael E. Wysession of Washington University in St. Louis is that the New Madrid Fault may be becoming less active, while activity on the Wabash Fault could be increasing. �1�#�1�����oDU�)���mq�lxxv�p�K��c���=Ķ 1����S�+��L: wmȱ�>Anu�!i�!n\�. But until Rover learns to tell us what he’s barking about, we won’t be able to employ animals in any predictive way. . Larger earthquakes You can help with a tax-deductible The Grayville Graben (∼20 km wide, ∼700 m maximum basement relief, and <40 km long [Bear et al., this volume]) underlying the Wabash Valley developed during rifting, perhaps in response to stress concentrations generated by a bend in the Reelfoot-Rough Creek-Rome rift system. The Wabash Valley Seismic Zone is located in Southeastern Illinois and Southwestern Indiana and it is capable of producing ‘New Madrid’ size earthquake events. This content is PDF only.
