So the archaeologists think that, after the destruction of 79 A.D., some survivors returned to Pompeii and found their homes half-buried in ash. They tried recover their belongings by digging underground, and some apparently attempted to rebuild their lives in their old homes, because they had nowhere else to go.

While their efforts ultimately proved to be futile, they did leave some historical artifacts behind (e.g. bread oven entirely made of salvaged materials), and the archaeologists recently unearthed them.

Modern day Indonesian and Philippines and Pac rim Island farmers don't stay away from volcanoes any longer than they have to. Mud flows different. Ash? That's plantable. And tuff forms, you can build with it.
