  • When Vesuvius exploded, (Pliny the Elder) apparently couldn't believe his luck at having an opportunity to witness such a momentous eruption. He climbed to the highest point he could find and watched the ash cloud develop. Later his nephew (Pliny the Younger) recalled how they saw the plume grow into a shape 'like an umbrella pine, for it rose to a great height on a sort of trunk and then split off into branches, I imagine because it was thrust upwards by the first blast and then left unsupported as the pressure subsided.' This classic, umbrella-like shape forms when a volanic ash plume hits winds going sideways in the upper atmosphere and spreads out. We now use the adjective 'plinian' for this type of ash cloud, after the man who first described it.
