The sinking of the ground, when the groundwater beneath it depletes.

This phenomenon is known as land subsidence. It occurs when the natural underground water reservoirs, such as aquifers, are removed faster than they can be recharged. As the groundwater is pumped out, the soil loses its support and begins to compact and sink. This can lead to a variety of issues, including damage to infrastructure, such as buildings, roads, and pipelines, as well as an increased risk of flooding. Land subsidence is a serious issue in many parts of the world, particularly in areas where groundwater is heavily relied upon for agriculture and urban development. Sustainable groundwater management practices are essential to prevent further land subsidence and preserve the integrity of the land.
