The impact of pyroclastic density currents duration on humans: the case of the AD 79 eruption of Vesuvius
Abstract Pyroclastic density currents are ground hugging gas-particle flows that originate from the collapse of an Antihistamine eruption column or lava dome.They move away from the volcano at high speed, causing devastation.The impact is generally associated with flow dynamic pressure and temperature.Little emphasis has yet been given to flow dura
