I live in Hilo area. I wouldn't be in a big threat (if the missile were to be aimed at logistical assets) but either way there's always the fallout.
There are two abandoned concrete bomb shelters from WW2 right across my house and they're in bad shape. It's been covered in dirt, boulders, thick vines, and used to have big avocado trees growing around it, a ton of trash from homeless folks. Recently they cleared out most of the vegetation put a new door and a lock on it.
Considering that it's made of concrete, it might be safer than my own house if the county cleans the bunker out and does minimal restoration to it.
On the other hand, probably invest in more of those SOS food bars off amazon, K-iodine, hazmat suits I guess.
