Summary:

Jaggar defines the symmetrical arrangement of Mauna Kea, Hualalai, Mauna Loa, Puu Keokeo [located on the lower southwest rift of Mauna Loa and considered to be a separate volcano {Bishop, 1906b, 1907a}], and Kilauea, as the "cross of Hawaii." Mauna Loa is at the center of the cross, and Jaggar considers it to be the youngest volcano, growing on a base formed by the other volcanoes. He considers Kilauea to be older and dying. He gives the first of his appeals to make Mauna Loa ("our great volcano") accessible by road and trail. He concludes by describing the cycles of Mauna Loa eruptions, noting in passing that eruptions on the southwest rift have been accompanied by earthquakes, whereas eruptions on the northeast rift have not, and predicts the next Mauna Loa summit activity to be before February 1, 1915, to be followed within 5 yrs by activity on the northeast rift. [Jaggar's age analysis runs counter to Dana's locus lines and Daly's ideas of Kilauea as a satellite of Mauna Loa and is denied by modern study, which shows Kilauea to be both younger and more active. The predicted summit eruption occurred in 1914, and the rift eruption followed in 1916, but broke out on the southwest rift zone, the first time historically that two successive Mauna Loa eruptions had occurred on the same rift zone. - Hawaiian Volcano Observatory]
