Which environmental consequence develops following sustained pyroclastic flows?

💡 Explanation

Extensive vegetation will be destroyed by pyroclastic flows; rain then mobilizes loose debris into lahars because surface stabilization by plant roots is absent. Therefore widespread vegetation loss and lahars are expected, rather than ozone depletion or deep ocean changes.
