How It Began

Sometime around 70 million years ago a cataclysmic rupture occurred in the Earth’s mantle, deep below the crust. A hot spot of liquid rock blasted through the Pacific plate like a giant cutting torch, forcing magma to the surface off the coast of Russia, forming the Emperor Seamounts. As the tectonic plate moved slowly over this hot spot, this torch cut a long scar along the plate, piling up mountains of rock, producing island after island. The oldest of these islands to have survived is Kure. Once a massive island with its own unique ecosystem, only its ghost remains in the form of a fringing coral reef, called an atoll. As soon as the islands were born, a conspiracy of elements proceeded to dismantle them. Ocean waves unmercifully battered the fragile and fractured rock.

Abundant rain, especially on the northeastern sides of the mountains, easily carved up the rock surface, seeking faults in the rock and forming rivers and streams. In forming these channels, the water carried away the rock and soil, robbing the islands of their very essence. Additionally, the weight of the islands ensured their doom. Lava flows on top of other lava, and the union of these flows is always weak. This lava also contains countless air pockets and is criss-crossed with hollow lava tubes, making it inherently unstable. As these massive amounts of rock accumulated, their bases were crushed under the weight of subsequent lava flows, causing their summits to sink back into the sea. What we call the Hawaiian Islands are simply the latest creations from this island-making machine. Someday they will disappear, existing as nothing more than footnotes in the Earth’s turbulent geologic history.
