What to do about a house in New Madrid County

No soluble bedrock is mapped here, so natural sinkholes are unlikely. Collapses from broken pipes or old mines are a separate risk.

Across 675 square miles, under one square mile of New Madrid County maps onto soluble rock. With about 15,212 residents (23 per square mile), much of the land is open, and the mapped rock may sit far from where people actually live. The figures come from 544 map points about 1.1 miles apart, so a pocket smaller than that can be missed or overstated.
