Land formation, lava tunnels, shelves etc.

[eigoya]

Has anyone had first-hand experience with finding geologic features on land here? When I worked planning stateside, you could research geography of any parcel. In Fairbanks, we read permafrost maps (before buying). Here with lava, it’s more fluid, I’m sure, but to get building permits, do they make some study on each parcel (I’m talking HPP not leilani) and where is that information kept? Is there anything else to consider when buying near coast (besides crumbling shelf or tube— not moon wobble)?TIA
