The presence of dead vegetation or bubbling in the ground above a pipeline serves as a common visual indicator of a gas leak due to the way natural gas interacts with the environment. When a gas leak occurs, it can displace the soil and create pockets of gas that may lead to bubbling at the surface, particularly if the gas is escaping from a pipeline. Additionally, the release of gas can damage nearby plant life, leading to areas of dead or dying vegetation, as the roots cannot access the necessary nutrients and water when gas disrupts the soil's oxygen levels.

This phenomenon is a practical way to detect leaks since gas is often odorless, and visually observing changes in the environment surrounding a gas pipeline can be crucial for safety. Identifying these signs can prompt timely investigation and remediation to prevent potential hazards associated with gas leaks.
