Which outcome is most immediate during intense pyroclastic surge?

💡 Explanation

Forest incineration happens because pyroclastic surges carry extreme heat and gases; the mechanism is rapid convective heat transfer. Therefore, immediate burning occurs first and fastest, rather than being delayed like mudflows, global dimming effects or ecological rebound processes.
