Now that you've told me about the fertile ground on volcanos I understand better about why people stay in such dangerous places. I lived half the year on the Big Island of Hawaii for many years and it was so lovely people forget the danger. In fact the whole island could just blow up without warning one day. There are dangers everywhere there. They have something called lava tubes, bubbles that solidified with the lava when it cooled. Once in a while a bull dozer driver is killed when he drives over a tube near the surface and falls a hundred feet or so onto solid lava. Bicyclers fear making a header onto Lava because it doesn't bend if your head hits it, causing a lot of Traumatic Brain Injuries. There are lots of places where there is a tradeoff between living in a beautiful but dangerous place. Oh, I forgot about the Vog (a local word for volcano fog) on the Big Island. Kilauea constantly leaks Sulfur Dioxide gas but some days are worse than others. A heavy day will close your sinuses and make you really lethargic. Otherwise it's a lovely place.
