It's on the island of O'ahu. Which is purely volcanic, created by the the Hawaii hotspot. And O'ahu is now fading away, because that hotspot has moved on. So part of the seeming sea level rise there could be due to the ground subsiding a bit, both from thermal contraction as deeper rocks slowly cool, and perhaps some draining of deep magma chambers. https://en.wikipedia.org/wiki/Evolution_of_Hawaiian_volcanoes https://en.wikipedia.org/wiki/Evolution_of_Hawaiian_volcanoe...
