On stratovolcano slopes, which outcome increases with lahar water saturation?

💡 Explanation

Lahars gain mobility through increased saturation, thus raising flow velocity; this is because increased pore pressure reduces the effective frictional resistance. The volume increase enhances momentum and lowers viscosity, thereby causing channelized debris flows rather than alternatives limited by saturation.
