Subsequently, a second column deposited a grey pumice with clastics up to 10 cm (4 in), temperature unsampled, but presumed to be higher, for 18 hours. These two falls were the Plinian phase. The collapse of the edges of these clouds generated the first dilute PDCs, which must have been devastating to Herculaneum, but did not enter Pompeii.
Since Herculaneum lay west of Vesuvius, it was only mildly affected by the first phase of the eruption. While roofs in Pompeii collapsed under the weight of falling debris, only a few centimetres of ash fell on Herculaneum, causing little damage; nevertheless, the ash prompted most inhabitants to flee.
Herculaneum, much closer to the crater, was saved from tephra falls by the wind direction but was buried under 23 metres (75 ft) of material deposited by pyroclastic surges. Likely, most of the known victims in this town were killed by the surges. People in Herculaneum, caught on the former seashore by the first surge, died of thermal shock.
The beach at the Herculaneum archaeological park is thought to be the site where more than 300 men tried in vain to save themselves from the natural disaster in 79AD while awaiting rescue by a ...
Henri de Saint-Blanquat identifies thirty-one plants in Pompeii, which, after growing in patches of bare earth, grow outward and attack the surrounding buildings, as well as dislodging tiles and mosaics. In particular, ivy grows along the walls, making parts crumble, and the roots undermine the foundations of the buildings.
The Herculaneum scrolls are hundreds of papyri that survived the eruption of Mount Vesuvius in AD 79. In their charred state, the ancient documents would crumble if anyone attempted to unroll them ...
ROME — Buried in ash after Mount Vesuvius’ cataclysmic eruption in A.D. 79, hundreds of papyrus scrolls have kept their secrets hidden for centuries. But archeologists have now been able to ...
Plinian eruptions or Vesuvian eruptions are volcanic eruptions marked by their similarity to the eruption of Mount Vesuvius in 79 AD, which destroyed the ancient Roman cities of Herculaneum and Pompeii. The eruption was described in a letter [1] written by Pliny the Younger, after the death of his uncle Pliny the Elder.
