An earthquake happened 17 years before the eruption.
Generally pyroclastic flows happen during an eruption.

The series of low-level tremors was a clue, but vulcanologists found it hard to persuade the state or federal government that an eruption was imminent. Only just before the mountain exploded, there were late efforts to evacuate the few that lived there. . . . I am a 'down-winder' of that eruption, and remember the devastation well.
Mount Vesuvius erupted suddenly, without warning. The people of the cities of Pompeii and Herculaneum were caught by surprise The cities were covered with ashes. The people did not have time to run away.
Before a volcano erupts, people are just living their lives, going about their daily routines. There typically wasn't much warning before a major eruption, and there still isn't a good early detection and warning system.
Yes, there is early warning before most volcanic eruptions. The primary sign is small earthquakes or land tremors and shakes near the volcano.
yes there was a few quakes before this disastrous eruption.....

Movement of high pressure magma underground typically occurs before a volcanic eruption. This magma is under such a high pressure that it can cause hydraulic fracturing of the surrounding rocks and even bulging of the crust. Both these events will release seismic waves (cause earthquakes). All these data help geologists predict that an eruption is about to occur.
The first eruption was about 3.825,this was before human was alive!!

Pompeii had experienced many earth tremors before the fatal eruption. Also the water supply began dropping.
