Which outcome results when pyroclastic flows enter a drainage basin?

💡 Explanation

Formation of lahars results because the pyroclastic flow's heat melts ice/snow or saturates loose sediment. This decreases stability via saturation, therefore flows turn into mudflows rather than stabilizing, since runoff rates rapidly rise.
