In the evening of November 14, 1959, Kilauea Volcano on the Island of Hawaii renewed activity with an eruption at its summit. This chapter is a detailed pictorial chronological narrative of that summit eruption and the interrelated flank eruption and summit collapse that followed. • The 1959 summit eruption occurred in Kilauea Iki, a collapse crater adjacent to the main summit caldera of Kilauea. • The eruption consisted of 17 separate eruptive phases, which ranged in duration from 1 week to 1%, hours. At the cessation of activity on December 20, 1959, Kilauea Iki Crater held 50 million cubic yards of lava in a lake 335-feet deep. After the summit eruption shallow earthquakes migrated out Kilauea's east rift zone, and on January 14, 1960, a flank eruption began near the town of Kapoho. During the next 37 days of virtually uninterrupted activity, 160 million cubic yards of lava, covering about 2,500 acres, was erupted. The small villages of Kapoho and and Koae, a United States Coast Guard station, and a number of residences along the coast were destroyed. Almost concurrent with the beginning of the flank eruption, the summit area of Kilaue•a rapidly deflated as magma moved from beneath the summit out the rift zone to the flank eruption area. Culmination of the summit subsidence occurred on February 7, 1960, when the floor of Halemaumau-a deep crater in Kilauea caldera-co!lapsed because of the withdrawal of the still fluid core of the 1952 lava lake. Two smaller collapses on March 9 and March 11 in Halemaumau marked the end of the 1959-60 eruption of Kilauea. 1840 May30 June (?) 1868 April2 April2 (?) April 1877 May4 May 21(?)

A suite of alkalic mafic and associated plutonic rocks occurs north of the Denali fault in the Windy terrane, and in the Hayes Glacier and southern Jarvis Creek Glacier subterranes of the Yukon-Tanana terrane. The suite consists of lamprophyre, alkalic gabbro, alkalic diorite, and monzonite, and diorite in dikes,
