Which hazard increases immediately following a lahar flow?

💡 Explanation

Floodplain sedimentation increases because lahar flows deposit large volumes of sediment downstream; therefore, sedimentation overwhelms typical river flow, rather than triggering distant tectonic shifts or unrelated fires since it is an immediate effect during and after the lahaar, rather than glacial formations.
