Which outcome results when pyroclastic flows enter water?

💡 Explanation

Tsunamis and lahars result from pyroclastic flows meeting water because rapid cooling causes steam explosions and debris flows via fluidization, therefore violent displacement occurs, rather than chemical sublimation or altered porous rock formation as might happen terrestrially.
