Abstract The Puu Oo eruption has been remarkable in the historical record of Kilauea Volcano for its duration (over 13 years), volume (>1 km3) and compositional variation (5.7–10 wt.% MgO). During the summer of 1986, the main vent for lava production moved 3 km down the east rift zone and the eruption style changed from episodic geyser-like fountaining at Puu Oo to virtually continuous, relatively quiescent effusion at the Kupaianaha vent. This paper examines this next chapter in the Puu Oo… 
Olivine-liquid relations of lava erupted by Kilauea volcano from 1994 to 1998: Implications for shallow magmatic processes associated with the ongoing east-rift-zone eruption
From 1994 through 1998, the eruption of K¯ilauea, in Hawai'i, was dominated by steady-state effusion at Pu'u ' O'¯ o that was briefly disrupted by an eruption 4 km uprift at Napau Crater on January
Kilauea East Rift Zone Magmatism: an Episode 54 Perspective
On January 29±30, 1997, prolonged steady-state effusion of lava from Pu'u'O'o was briefly disrupted by shallow extension beneath Napau Crater, 1±4 km uprift of the active Kilauea vent. A 23-h-long
Magma-reservoir processes revealed by geochemistry of the Pu'u 'ō''Ō-KŪpaianaha eruption
Geochemical data were examined for a suite of approximately 1,000 near-vent lava samples, collected from January 1983 to October 2001, from the Pu'u 'O'o-Kupaianaha eruption of Kilauea Volcano,
238U–230Th–226Ra–210Pb–210Po Disequilibria Constraints on Magma Generation, Ascent, and Degassing during the Ongoing Eruption of Kīlauea
The timescales of magma genesis, ascent, storage and degassing at Kı̄lauea volcano, Hawai‘i are addressed by measuring U-series radionuclide abundances in lava and tephra erupted between 1982 and
1998 Eruption at Volcán Cerro Azul, Galápagos Islands: I. Syn-Eruptive Petrogenesis
The 1998 eruption of Volcán Cerro Azul in the Galápagos Islands produced two intra-caldera vents and a flank vent that erupted more than 1.0×108 m3 of lava. Lava compositions changed notably during
A Petrologic Perspective of Kīlauea Volcano's Summit Magma Reservoir
Two hundred years of magmatic history are documented by the lavas and tephra sampled from K olauea's historical summit eruptions. This paper presents detailed petrographic and geochemical data for a
Accumulated Puʻu ʻŌʻō magma fed the voluminous 2018 rift eruption of Kīlauea Volcano: evidence from lava chemistry
The 2018 rift eruption of Kīlauea Volcano presents a superb opportunity to decipher the underlying role of magmatic processes on the behavior and hazards of basaltic volcanoes. Here, we examine the
Crustal Contamination of Kilauea Volcano Magmas Revealed by Oxygen Isotope Analyses of Glass and Olivine from Puu Oo Eruption Lavas
Oceanic island basalts have a large range in δ^(18)O values (4.5−7.5‰) compared with the assumed primordial mantle values (5.5–6.0‰) and with mid-ocean ridge basalts (5.7 ± 0.2‰). Some Hawaiian
Rapid Change of Lava Composition from 1998 to 2002 at Piton de la Fournaise (Reunion) Inferred from Pb Isotopes and Trace Elements: Evidence for Variable Crustal Contamination
After an unusually long quiet period of nearly 6 years, in 1998 the Piton de la Fournaise volcano started a new cycle of intense volcanic activity. We report geochemical data on the first nine events
Magmatic history of the East Rift Zone of Kilauea Volcano, Hawaii based on drill core from SOH 1
Abstract Deep drilling has allowed for the first time an examination of most of the shield stage of a Hawaiian volcano when it is centered over the hotspot and most of its volume is produced. We


Petrology of lavas from episodes 2–47 of the Puu Oo eruption of Kilauea Volcano, Hawaii: Evaluation of magmatic processes
The Puu Oo eruption of Kilauea Volcano in Hawaii is one of its largest and most compositionally varied historical eruptions. The mineral and whole-rock compositions of the Puu Oo lavas indicate that
Petrologic constraints on rift-zone processes
The Puu Oo eruption in the middle of Kilauea volcano's east rift zone provides an excellent opportunity to utilize petrologic constraints to interpret rift-zone processes. Emplacement of a dike began
A quantitative look at the demise of a basaltic vent: the death of Kupaianaha, Kilauea Volcano, Hawai'i
Abstract The Kupaianaha vent, the source of the 48th episode of the 1983-to-present Pu'u 'O'o–Kupaianaha eruption, erupted nearly continuously from July 1986 until February 1992. This investigation
The 1983–86 Pu'u ‘O’o eruption of Kilauea Volcano, Hawaii: a study of dike geometry and eruption mechanisms for a long-lived eruption.
Abstract The 1983–1986 Pu'u ‘O’o eruption of Kilauea volcano had a very distinctive episodic character which later changed to steady-state activity. In this paper we present a physical model of
Motion of Kilauea Volcano during sustained eruption from the Puu Oo and Kupaianaha Vents, 1983–1991
Kilauea erupted almost continuously from January 1983 through 1991. Although the summit began subsiding during the rift zone dike intrusion that initiated this eruption, remarkably steady ground
Geochemistry of the 1984 Mauna Loa Eruption: Implications for magma storage and supply
The 1984 eruption of Mauna Loa volcano, Hawaii, produced about 220×106 m3 of lava of remarkably homogeneous composition. No significant compositional changes occurred during the 22-day eruption, and
