Which of the hazards brought by volcanic eruption would you consider the most devastating? Explain.

Lava-flows, together with gas exhalations, mud pools, hot springs and rock avalanches, have an intermediate range, being most lethal in the surrounding of the volcano. Tephra fall can be dangerous, especially for persons with respiratory problems, over a distance of 270 miles (170km).

Hope this helps!

Ambivalence means uncertainty, doubt, and hesitation.
