Yep... rip and roll it with a D-9 where you intend to build as it's a must in Ah Ah.
After that... if you want to be off the ground, pour some round or square footings about 8-16" into the lava rubble and bolt some steel posts atop the footings or pour some more small columns atop the footings and or do a monolithic pour for the columns and footings in one shot.
It's a very simple process although I believe if using posts & footings only - I swore that I read while skimming through a revised code a few months back, the new code stipulates a rafting pad be poured to connect the footing blocks and that’s probably applicable to any solely based footing block and column base structure. In some measure or another, a pad or direct connect foundation is required to a particular point now.
I just finished up the 4th or 5th design for our house and it will use several footing blocks and columns but it’s all based around and atop a 26’X38’ turn down footing pad so rafting out to the footing blocks will not be necessary though there are exterior pads that do by default connect most of them.
E ho'a'o no i pau kuhihewa.
