When I visited Pompei and Herculaneum my first thought is I couldn't help but to think how stupid humans are for rebuilding those towns in exactly the same place, and even closer to the volcano than the ancient destroyed towns.

Farms, I get it -- fertile soil -- but why cities? Did people not learn from the historical records of their time, to draw lines around the boundaries of destruction and not build again within those lines?

I feel a bit the same about other similar hazards. Cities built on flood plains that regularly get washed away. Cities built on volcanic hotspots with regular serious earthquakes. Cities, as you say, in the shadow of active volcanoes. But people always seem to think "it won't happen again."

Also reminds me of this thing I saw in satellite maps near Mt. Shasta. Train track cutting right through a lava flow, and a highway (that might serve as a valuable escape route) cutting right next to it. Seriously? Are humans that stupid? The very FIRST thing I see when I look at this satellite map is "oh shit lava how about we stay the hell away from it"

And yet protagonists survive after going through a pyroclastic flow routinely in the movies, such as Jurassic World: FK and 2012. It is a recurring trope in movies!

Well, most bad Hollywood movies are not scientifically accurate.

Even the good ones are not very scientifically accurate, tbh.

Hi there, I live around 30 km from Pompeii and I'm in a "safe zone". I'm only expected to receive some ashes in case of eruption (if the eruption is like the one of 1600, that is more probable but less strong than the one of 79BC).

After a few years after the eruption, nobody knew the exact location of Pompeii and Ercolanum, and also for quite some time these two areas were unhabitated and used only for farming. The emperor at the time of the eruption, Tito, tried to rebuild the cities but nobody wanted to live there anymore.

They only found out that Pompeii was there around 1500-1600. The repopulation of the area has happened during the last century, mainly because Italy was, after the second world war, in an economic boom and people built houses (and factories) without any permit. Politics was usually corrupted or "closed their eyes" for votes.

And here we are. At the point we are now, it is impossible to relocate this huge amount of people (around 2M) anywhere. The evacuation plan itself is a joke, due to the nature of the eruptions of a stratovolcano.

So, let's hope for the best, as there's nothing we can do to prepare for the worse.

The airport in Kona on Hawaii is built on a lava flow from Hualalai’s last major eruption about 200 years ago. Hualalai is still considered an active volcano, too. Maybe they’ve got a force field they haven’t told anyone about.
