Land subsidence is when the ground sinks or settles down. It happens when the soil or rock beneath the surface gets compressed or collapses. This can occur naturally because of processes like erosion or underground water movement, or it can be caused by human activities such as mining, groundwater extraction, or the weight of buildings. Overall, it refers to the sinking of land surface, which can lead to problems like sinkholes, damage to infrastructure, and flooding.
