Which risk increases when a river's sinuosity nears cut-off?

💡 Explanation

When a river channel's meanders become very pronounced, the *neck* between bends narrows, forming an oxbow shape progressing to a shortcut. *Avulsion accelerates* because the river flows straight, thereby favoring cutoff rather than the path of least resistance, rather than seismic adjustments.
