While the two may seem completely unrelated, a hurricane on the surface and a sinkhole below the ground, hurricanes, storms and heavy rains can have a dramatic impact on sinkhole formation. In fact, heavy rain may be the biggest driving force in sinkhole development. Everyone probably thinks of sinkhole activity as a hole below the ground and in a way that is right. However, without any movement of the earth above that hole it just sits dormant and not causing any problems. So what causes the soils to move downward? Gravity if course has an impact but water is the biggest driving force of soil movement. Water entering the ground surface can drag soil particles down and into voids bellow ground. Once this happens we see the true impact of sinkhole activity and the soils begins o move and ravel downward resulting in an impact at the surface.
