Re: One does wonder
It most certainly had. The people who were killed following the last eruption were the generation who had pretty much rebuilt the city following a devastating eruption a number of years earlier.
IIRC, the people living there at the time didn't know that Vesuvius was a volcano. The previous eruption had been almost 2000 years earlier, and before the eruption in 79 AD, the mountain wasn't volcano-shaped as it is now with a big crater, but had a single peak some 4,500 metres high.
Pompeii had been rebuilt several times after earthquakes, but the Romans didn't link these to volcanic activity, thinking that either could happen at any point at the whim of the gods.
