Where it comes from
From pyroclastic + flow.
noun pyroclastic flows
-
A dense flow of volcanic ash, dust, rocks and debris that cascades at high speed down the slope of a volcano during an eruption.
Most of the material was erupted in the most dangerous way as ‘pyroclastic flows’: incredibly hot volcanic fragments all buoyed up with gas that can travel fasted than a speeding car in pulse after pulse.
Similar: pyroclastic density current, PDC, pyroclastic surge
- Used other than figuratively or idiomatically: see pyroclastic, flow: flow (uncountable) of pyroclastic particles. Viscous debris flow is different not only from inertial debris flow but also from granular flow, pyroclastic flow and snow avalanche, because the effect of inelastic collision of particles does not play an important role in viscous debris flow.
