Various experts agree that many areas exhibit tell tale signs that a sinkhole could form. While it may be difficult to predict the magnitude of the sinkhole or when exactly it can come up, noting down a few of these sinkhole symptoms can help you be prepared for this phenomenon.
The doors and windows don’t fit
When a sinkhole is in the making, a house situated on the uneven surface may bend to a side. This causes inconvenience in closing and opening doors/ windows. If you live in a sinkhole prone area, and the doors and windows don’t seem to fit properly, for no apparent reason, probably it is time to get not a carpenter, but a geologist.
Depression in the yard/ street
If you notice a circular depression either in your yard, your neighbor’s yard or the nearby street, then it could be a sinkhole in the making. You can ask experts to check the region if you notice such phenomena.
Circular patches around wilting plants
Nature is the best indicator of sinkhole activity. If you notice that your plants are wilting and appear to do so within an unusual circular patch, it could be a sinkhole activity again.
Sediment in water
If the water supply to your house, appears to have sediment particles in it, then it could be a case of ruptured pipeline. It could also be that the ground water has imbibed within it dissolving rock of the region. You may want to get it checked.
Appearance of cracks on a building
Another important sign that conveys about sinkhole activity is the formation of large cracks and fissures on external and internal walls. These indicate that the building is on unstable ground and pressure is being exerted from below.
An actual sinkhole opening up
