Fragment propagation refers to the process by which small pieces, or fragments, of a larger entity spread or move away from the original source. This concept is often observed in various fields, such as biology, where it can describe how plant cuttings grow roots and develop into new plants. In technology, it can refer to how data packets travel through networks. In the context of geology, fragment propagation can occur during events like landslides or volcanic eruptions, where debris is dispersed over a wide area. Understanding this process is crucial for predicting the impact of such events and for implementing safety measures in affected regions.
