And as Reno89519 points out, the impact goes even further. One sad effect, ironically, is that Hawaii Volcanoes National Park is closed indefinitely. It gets over 2 million visitors annually.
What many people seem to fail to realize is the downwind vog along Kona (where most of the resorts + 80% of the island population is located) is not only visually depressing, but unhealthy to boot. For those familiar with western states forest fires, while they too make any experience highly unpleasant and disrupt the quality of life, they're usually limited to late summer/early fall and don't last forever.
The human time scale is so tiny that I wonder if the last 200 hundred years of HI history was really just an anomaly. Perhaps the islands are somewhat actually unlivable, and it was only due to dormant activity that allowed relatively recent development and utilization. I mean, when you see how massive the Mauna Kea & Loa domes are, you gotta wonder just how much lava flow had to come out to build those peaks.
In comparison, Kilauea is just a small baby. For it to reach a similar size/shape would require untold amounts of lava with attendant dangerous levels of vog.
