My thesis is that there must be some order in time and space for what is obviously 1,700 miles of submarine volcanic upbuilding in the Hawaiian chain. Active volcanoes are hot and erupting in Hawaii; sunken ones are covered with coral at Midway Island; and intermediate ones, half coral and half lava, are in the middle of the chain. Disregarding the ocean water, all of these are gigantic mountains below sea level. On the island of Hawaii I found symmetry, which I called “The cross of Hawaii” in an address to the Honolulu Chamber of Commerce in 1912. I noted that Mauna Kea forms the top of a cross on the map; the upright extends along the southwest rift of Mauna Loa, and two symmetrical curved arms extend to Hualalai summit and Kilauea summit. The lava flows from Mauna Loa north and south arrange themselves symmetrically about this design, with every evidence that Mauna Loa dome was piled up in a spoon underlaid by Hualalai, Mauna Kea, and Kilauea. It is obvious on the map that Mauna Loa upbuilding was obstructed by grandpa Mauna Kea and that it has been forced off to the southwest by the two daughters, to build the elongate point of the island. Kilauea is old on the Haleakala, Kohala, Kea line; and Hualalai is old on a right angle line at Kea. From my training in physiography under W. M. Davis of Harvard, I was convinced when I first saw Hawaii and studied the books about it that downward faulting toward the sea bottom, of sliding island blocks, is conspicuous. It shows in the V-shaped fracture of Haleakala Crater, a broken sector, and in the straight fracture of the north half of Molokai volcano, leaving the mighty cliffs there. It shows in the eastern half of Kohala volcano leaving the fault facets and hanging valleys of Waimanu, and in the Mohokea embayment of the southeast end of Mauna Loa. The embayment shows evidence of the breakdown of an ancient crater as described by Hitchcock. Moreover, Kilauea, Wood Valley, Mohokea, and Waiohinu amphitheater are four old calderas of faulting in a line. This seemed to me confirmed by the down-faulted steps of the southeast side of Kilauea Mountain, and the observed down-breaking there of the shoreline during earthquakes. This, in 1868, drowned coconut trees below the sea and caused big earthquakes on a submerged fault in 1868 and 1952. Such action was further confirmed by our experience of a down-faulted block during earthquakes at Kapoho in April 1924, before Halemaumau exploded, confirming the view that the active volcanoes break downward in slices along shorelines, even when they swell upward around craters. Harold Stearns always combatted the idea of faulting and made Mohokea, Haleakala, and Waipio erosion forms; but this I cannot accept.
