Subsidence is a geological term that refers to the gradual or sudden sinking, settling, or caving in of the Earth's surface. It is typically caused by the removal or depletion of underground fluids or the collapse of underground spaces. Subsidence can occur naturally, but it is often induced or accelerated by human activities such as mining, excessive groundwater extraction, oil and gas extraction, and even construction.
In natural subsidence, the ground sinks due to various factors such as the dissolution of soluble rocks, geological faulting, or the compaction of sediments over time. Human-induced subsidence, on the other hand, is caused by the lowering of the water table due to excessive pumping of groundwater, resulting in the compaction of the underlying soil layers.
The consequences of subsidence can be detrimental to infrastructure and the environment. Buildings, roads, bridges, and other structures can suffer structural damage or even collapse due to the uneven settling of the ground. In coastal areas, subsidence can lead to the increased risks of flooding and the intrusion of saltwater into freshwater aquifers.
Monitoring and managing subsidence are essential to mitigate its negative impacts. This includes techniques like land surveying, geotechnical investigations, and implementing regulations and preventative measures. Additionally, the implementation of sustainable groundwater management practices can help reduce the occurrence of subsidence.

The word "subsidence" comes from the Latin term "subsidentem", which is the present participle of the verb "subsīdere". "Subsīdere" is composed of two Latin elements: "sub", meaning "under" or "below", and "sīdere", meaning "to settle" or "to sink". When combined, these elements form the meaning of "subsidence" as the act or process of sinking or settling down.
