It always amazes me how young this island is yet how big it is but that might be because I tend to study things that have been around for billions of years! Hawaii Island is less than half a million years old. I'm doing this bit from memory but think HPP was last covered in lava about 500 years ago, other areas south of there much less. On the other hand, yes, it takes several generations between lava flows, so it's not something you probably should worry about in lava zones three and above, but it's a fast moving island, at least geologically speaking...
