My dad was serving in Italy at the time. Got a ring side seat at the eruption. Made an ash tray out of the lava. Still has it in his old trunk.
On March 6, the first earthquake struck the area. Another hit on March 11, and two more hit on March 13, it was reported.
It's crazy everywhere, near my home recently:
Statistically, volcano / lava eruptions have killed more life than any other process. The Permian Extinction event of 252 million years ago (252ma), that ranks as the worst of the great 5 extinctions, shows strong coincidence with the Siberian Traps flood basalt lava eruption. When the red stuff comes out, it is best to be far, far away. Given the nature of the vulcanology of the area, an eruption of Campi Flegrei would be high altitude, high ash that is maximum disaster for modern civilization pattens. UGH!
Wherever I go, I hope there’s rum!
Tambora, the cause of “the year without a summer” left a caldera 5 miles in diameter. The Campi Flegrei caldera is 7.5 miles in diameter. Try cubing those diameters to determine how much more “nuclear winter” CF could have caused. I would do it myself, but never was a math wizz.
Sunken Civ: I looked at some of the articles on CF that you provided the link for. On one of them I found the link below which is an interesting one on the language possibilities of Neanderthals.

I meant to say volcano, not earthquake, regarding the volcanic eruptions at St. Vincent and Santa Maria. Another interesting report was from a ship at sea. Apparently at the time of Pelee’s final big eruption, the sea became so hot that sharks and other fish were jumping to get out of it. Also, the sea dropped about 4 feet suddenly, I would suspect from the sudden emptying of a large magma chamber spread over a wide area under the crust.
The Phlegraean Fields Neapolitan: Campe Flegree, from Greek phlego, “to burn”)[2][citation needed] is a large volcanic area situated to the west of Naples, Italy. It was declared a regional park in 2003. The area of the caldera consists of 24 craters and volcanic edifices; most of them lie under water. Hydrothermal activity can be observed at Lucrino, Agnano and the town of Pozzuoli. There are also effusive gaseous manifestations in the Solfatara crater, the mythological home of the Roman god of fire, Vulcan. This area is monitored by the Vesuvius Observatory.
The area also features bradyseismic phenomena, which are most evident at the Macellum of Pozzuoli (misidentified as a temple of Serapis): bands of boreholes left by marine molluscs on marble columns, show that the level of the site in relation to sea level has varied.

Scary.
Thanks glee'.
Tambora's crater is 3.7 miles across; although some sources put the amount of crud expelled at 50 cubic miles, the current consensus estimate is about 36 cubic miles.In 2004, scientists discovered the remains of a village, and two adults buried under approximately 3 meters (nearly 10 feet) of ash in a gully on Tamboras flank -- remnants of the former Kingdom of Tambora preserved by the 1815 eruption that destroyed it. *Wow, they must have been thirsty when they found 'em.
Volcanic eruptions are locally devastating, but any worldwide effects are mild. The Campi Flegrei eruption 39,000 years ago has been linked to the so-called extinction of the Neandertal (see the keyword links for a couple of topics), the fact is, volcanic eruptions and their effects are typically exaggerated and/or misstated.
The wikipage-ia has the figure of 48 cubic miles expelled in that CF eruption -- which compares well with Tambora -- followed by a period of 25,000 years of undersea activity which over that time produced a volcano 9.3 miles in diameter (that's not the crater, apparently, but the whole cone etc).
After a couple of thousand years of apparent quiesence, the current, even slower, and geologically different activity started going on, continuing about 7500 years, with Monte Nuovo forming in the 16th century. Overall the caldera is a lake, but there are a bunch of big muddy sloppy gassy vents where the activity is going on today.

"It was the best fishin' day we ever had!"
