Question

Quizplus · Accepted Answer

Pyroclastic flows move at incredibly high speeds, often exceeding 100 km/hr, making them much harder to escape. They can also contain hot gases, ash, and large boulders, making them much more dangerous than lava flows. While lava flows can also cause damage and destruction, they are generally slower moving and more predictable, allowing for better evacuation and preparation.
