If you check it out, tou won.t find any recorded eruption between the Avellino (circa 1660 BC) and the Plinian at 79 AD.

 

If you actually read the article, you will find them.

What explanation?

 

 

edit: just noticed you edited your post.

I wasn't referring to my own article or the 217BC eruption.

 

You said "If you check it out, tou won.t find any recorded eruption between the Avellino (circa 1660 BC) and the Plinian at 79 AD.", while the article states that

During this period of activity there were three plinian eruptions: the eruption of Pomici di Mercato (8,000 years ago), the eruption of Pomici di Avellino (3,800 years ago) and the Pompei eruption (79 A.D.). These eruptions alternated with at least six subplinian eruptions, dated between the Pomici di Avellino and Pompei eruptions, and preceded by long periods of inactivity.

You're right, my mistake.

I was counting only the Plinian eruptions.

 

BTW, here's the Volcanic Explosivity Index (VEI):

Pliny the Younger tells us the romans weren't bothered by earth tremors - they occured often enough on a small scale to become an unwelcome but ordinary event.

 

His recollections have been dismissed as nonsense pretty much up until the modern day, but he made a pretty good record of what happened. Its noticeable from the actions of his father that the effects of a volcanic eruption were simply not known, and therefore whilst there was some immediate hazard, the true scale of the peril wasn't understood.

 

Pliny the Elder received an SOS from a woman named Rectina (she didn't survive), and although he sailed with a number of vessels to rescue her and those with her, he instead was forced to sail further south to Stabaiae where he stayed overnight in the villa of his friend, Pomponianus, where he was nearly trapped in his bedroom by the accumulation of volcanic refuse. Making his way to the beach that morning he overcome by the fumes.

 

In a way he was lucky. Many victims were crushed as the roofs collapsed under the sheer weight of pumice, others were overwhelmed by pyroclastic flows.

 

These violent clouds of hot ash and dust are not for the faint-hearted. The cloud will burn the skin, the lungs, which are also lacerated by tiny volcanic glass fragments, and the dust will form cement in the throat and suffocate the individual. Moving at up to two hundred miles an hour, the cloud can travel for some distance as the refugees at the boathouse in Stabaiae found to their cost as they waited for a boat to evacuate them.
