One of the things the host brings up is that a US Geological Survey volcanologist was pivotal in preventing area governmental agencies from ending the "red zone" that had been put in place around the mountain to prevent anyone who didn't need to be there from being there, as homeowners who lived within the "red zone" were demanding to return to get their personal possessions. 

Sadly, he was killed when the volcano went erupted, as the "red zone" was calculated based on a vertical eruption when it actually erupted laterally, meaning that many areas considered "safe" were actually in the area of effect. 

It's a tragic reminder of the need to have bug-out bags and other critical material handy in case of an evacuation, as there may be no means of safely returning for an extended period.
