Death toll up to 47 bodies recovered. All reported missing have now been accounted for.

Article confirms that most of the injured hikers were due to falling rocky debris, so the many mentions of fractures that I saw were due to impact injuries and not falls.

The chance of getting caught in an eruption is tiny, but the story interests me in terms of how people reacted and survived such a situation.

It's not easy to deduce if certain actions increased chances for survival. There were a large number of survivors who took shelter inside buildings near the summit, and some found dead nearby in the open, but we don't know if those who died were simply closer to the eruption than the ones who took shelter. The largest number of survivors are those who hiked down, but we don't know how high up they were. They might have just been at a lower elevation when the eruption started.

I do get the sense that taking shelter improved survival. I'm not sure what I would do when the adrenaline is pumping--head downhill or head for shelter, particularly if the shelter is possibly above you, towards the imminent threat.
