Kure is 34 million years old, Kauai is about 4 million years old, BI is about 800K (various books say between 600K-1,000,000) they get this figure by adding up the height of Mauna Loa/Mauna Kea etc at their tallest and then average out the thickness of the average flow and how often they cover ea other on average ie each flow averages 3'-5' thick and covers the same spot every 100-150 years on average...
there used to many more islands above Kure but as they go farther north as the plate moves over the hot spot the water gets colder and coral ceases to live and thrive... thus ea island sink below the surface when it gets to this spot in ocean.... unlike a former volcanic island that became an atoll in warmer waters which grows up (coral) at the same rate as it sinks (volcanic islands slowly sink) so stays just above the sea level.

save our indigenous and endemic Hawaiian Plants... learn about them, grow them, and plant them on your property, ....instead of all that invasive non-native garbage I see in most yards... aloha
