Pyroclastic Flow 3
Pyroclastic Flow 3 : Natural Disaster. A cloud denser than air made up of fragments of rocks and gas, characterised by high temperature and speed. It is generated by the collapse of an eruption plume supported either by a dome or by a lateral blast. It tends to flow to the ground under the force of gravity, to channel into valleys and fill depressions and some have enough energy to make their way over even tall morphological barriers. Their distribution in the area will therefore depend on morphology
