Rivers Partly to Blame for Sinkholes
ST. LOUIS (AP) - Sinkholes periodically cause problems in eastern Missouri, and an expert at the Missouri University of Science and Technology says the Mississippi River and its tributaries are part of the problem.
Geological engineer J. David Rogers told KMOX Radio that rivers in eastern Missouri cause seepage that over time erodes the soil. Parts of the St. Louis region and Cape Girardeau in southeast Missouri have been victimized by significant sinkholes in recent years.
Rogers says the sinkholes have no connection to the New Madrid fault line, although he says a strong earthquake could cause existing sinkholes to collapse.
