I would like to live in Hawaii someday (Big Island) and take my chances with the volcano - especially since it is, as you describe, the type of volcano that gives you plenty of warning.
I like driving around the Big Island, all the different micro-climates. Some parts look like a rain forest and other parts look like ranch land in Texas.
I love the big island. We own property there (inherited years ago) and have tried and tried to get hubby to move there. I’m thinking about putting a yurt on our property so that anyone in the family can go when they want. Daughters boyfriend is an electrician and said he’d do solar on it. We’re headed there in September to get the process started.

I actually had plans to do a central living area surrounded by 3 small yurts as bedrooms. A small yurt is a good way to start.
When i left for college in 1962, our population was about 90,000 on the island. We are now beyond 200,000 and growing. Just driving around the island only let’s you notice what’s available. Get a 4 wheel drive and go to places like Waipio Valley, Mauna Kea summit, Mana Road, etc to really see snow, sunny beaches, desert and rain forest in one day. But please, don’t try to make the Big Island like the place you left when you get here. It is a different lifestyle, different culture, different climate. Embrace it as it is or you will not like it.
