What causes a sinkhole in your yard?
Sinkholes are the result of collapsing underground bedrock, leaving behind a hole. They occur in nature but also can be a result of humans cutting down trees and leaving rotting stumps behind, or because of buried construction debris. Look for rotting tree stumps or old construction debris.
Where do sinkholes happen at?
The USGS calls areas like this “karst terrain.” According to the USGS, about 20 percent of U.S. land is susceptible to sinkholes. The most damage from sinkholes tends to occur in Florida, Texas, Alabama, Missouri, Kentucky, Tennessee, and Pennsylvania.
Can you fix a sinkhole?
A sinkhole is best repaired by excavating to rock and then building an aggregate filter in the hole. Step 1: Excavate the sinkhole down to rock if possible. Step 2: Put a layer of large stones in the hole (cabbage size). Step 3: Put a layer of smaller stones on top (fist size).
What is a sinkhole and what causes them?

What are the effects of a sinkhole?
Natural sinkholes can form on land and in the ocean as well. When they are formed on land, they can change the general topography of the area and divert streams of underground water. If they form suddenly in areas with heavy population, they can cause a lot of damage to human life and property.
How deadly are sinkholes?
Sinkholes can be very destructive, but they are rarely deadly . An exception occurred in February 2013, when a sinkhole suddenly opened up under a bedroom in a home in Seffner, Fla., sending Jeffrey Bush, 37, tumbling to his death.
