Puna is a district on the southern tip of the Big Island. Are you saying 90% of Puna, or 90% of the Big Island was covered with lava flows in the last millennium?

90% of Puna. Puna is more on the right hand lower side, the souther tip is Kau distict. Kau also has a lot of recent lava flows. So does Kona, north and south. But Puna is the most active.
