What causes sinkholes to form in urban areas?

Sinkholes in urban areas are often caused by the collapse of underground cavities, exacerbated by human activities. Leaking water pipes, drainage systems, or excessive groundwater extraction can erode the underlying soil and rock, leading to instability. Construction and heavy traffic add stress to already weakened ground. Sinkholes may appear suddenly and pose significant risks to infrastructure and safety, especially in areas built on limestone or other soluble rock formations.
