On 5 November 1967 Kilauea volcano began erupting lava from vents on the floor of its summit pit crater. Halemaumau, 170 meters deep. This eruption ended nearly 2 years of the quiescence that followed a short lived eruption on the east rift zone of Kilauea in December 1965 (1). The 1967-68 eruption was the first activity in Halemaumau since July 1961 (2). The eruption ceased on 13 July 1968 following 31 separate phases of fountaining separated by short periods of quiescence. Six weeks after the end of the summit eruption, a short eruption occurred on the upper east rift zone of Kilauea. As the article goes to press there have been four eruptions, all of the upper east rift zone. The last of the four began in May 1969 and have just completed its seventh phase. The article summarizes the eruption in Halemanumau and complements an article Fiske and Kinoshita on the deformation that preceded the eruption (3). The methods of study and the instrumentation used during the eruption are the same as those discussed in the earlier article. The locations of all seismographs tiltmeter stations and bench marks are shown in Fig. 1.
