That is a much better representation of what occurred than the movie though I
still have a few quibbles based on the latest works, including Paul
Roberts "Life and Death in Pompeii and Herculaneum" for the 2013 British Museum exhibition:
The largest dense airborne projectiles were about 1'
diameter. Overall the 6" to 1'
diameter projectiles were quite
rare. Tiny pebbles and pumice made up 99.99% of the ejecta which landed on Pompeii. Thus the massive impact on the temple is unlikely.
The greatest structural destruction occurred when the pyroclastic flows swept over Pompeii, whereas the video shows most of the destruction, including to the temple,
complete earlier due to the "pumice rain". Yes many small buildings collapsed early due to pumice (
weight load on roof), or burned down due to
lamp fires, but temples/columns etc generally survived until the pyroclastic flows.
The morning is too light. It was described as continued night.
The pyroclastic flows actually consisted of two stages - a surge of lighter materials (super-heated dust and gasses) followed by a flow of denser material. And they would have glowed in the dark due to the heat.
Finally, the comment at the end is wrong. Pompeii was not lost in a short time. It was buried to slightly less than two stories height. Large parts stuck up through the new surface level. Large
scale excavations, possibly ordered by
Titus, plus extensive looting occurred soon after.
Nevertheless, despite these quibbles this is a
good video of a proper lava-less Plinian eruption. It shows many accurate details including the late evening "first pyroclastic flow" which went down the western slopes of Vesuvius and completely destroyed Herculaneum. Also the multiple flows which assailed Pompeii with the walls stopping the first one or two.
