The 1875 rhyolitic eruption of Askja volcano in Iceland was a complex but well-documented silicic explosive eruption. Eyewitness chronologies, coupled with examination of very proximal exposures and historical records of distal deposit thickness, provide an unusual opportunity for study of Plinian and phreatoplinian eruption and plume dynamics. The ∼ 17 hour-long main eruption was characterized by abrupt and reversible shifts in eruption style, e.g., from ‘wet’ to ‘dry’ eruption conditions, and… 
Dispersal of key subplinian–Plinian tephras from Hekla volcano, Iceland: implications for eruption source parameters
Hekla is the most active silicic volcano in Iceland, with 18 subplinian–Plinian eruptions since AD 1104. In the period 1970 to 2000, the frequency of such eruptions increased to once every decade.
First timeseries record of a large-scale silicic shallow-sea phreatomagmatic eruption
Phreatomagmatic eruptions are one of the most common styles of volcanic eruptions on Earth1–2. Recent studies have highlighted the importance of the eruption depth and magma discharge rate on the
Magma Vesiculation and Nature of the Explosive Activity in the 2011 Grímsvötn Eruption
Grímsvötn is a basaltic, subglacial volcano and is the most active volcano in Iceland. It is known for phreatomagmatism and historically large fissure eruptions from its associated fissure swarm. The
Rifting and recharge as triggers of the mixed basalt–rhyolite Halarauður ignimbrite eruption (Krafla, Iceland)
We present a petrologic study of the ca. 110 ka Halarauður eruption (7 ± 6 km3 magma), associated with collapse of Krafla caldera in northeast Iceland. Whole-rock compositions of juvenile Halarauður
The 1963–1964 eruption of Agung volcano (Bali, Indonesia)
The February 1963 to January 1964 eruption of Gunung Agung, Indonesia’s largest and most devastating eruption of the twentieth century, was a multi-phase explosive and effusive event that produced


The pyroclastic deposits of the 1875 eruption of Askja, Iceland
The 1875 explosive eruption of Askja, Iceland was part of a series of regional volcanic and tectonic events which took place in the northern rift zone in 1874 and 1875. These events were marked by
Vent migration and changing eruptive style during the 1800a Taupo eruption: new evidence from the Hatepe and Rotongaio phreatoplinian ashes
The 1800a Taupo eruption was one of the most complex silicic eruptions worldwide within the past 5000 years. New work on phases 3 and 4, the Hatepe and Rotongaio ashes, has identified a mappable
The physical volcanology of the 1600 eruption of Huaynaputina, southern Peru
Abstract. Volcán Huaynaputina is a group of four vents located at 16°36'S, 70°51'W in southern Peru that produced one of the largest eruptions of historical times when ~11 km3 of magma was erupted
Sedimentological analysis of the tephra from the 12–15 August 1991 eruption of Hudson volcano
The tephra fallout from the 12–15 August 1991 explosive eruption of Hudson volcano (Cordillera de los Andes, 45°54′ S-72°58′ W; Chile) was dispersed on a narrow, elongated ESE sector of Patagonia,
Types of eruptions of Etna volcano AD 1670–2003: implications for short-term eruptive behaviour
Analysis of the historical records of Etna’s eruptive activity for the past three centuries shows that, after the large 1669 eruption, a period of about 60 years of low-level activity followed.
The plinian eruptions of 1912 at Novarupta, Katmai National Park, Alaska
The three-day eruption at Novarupta in 1912 consisted of three discrete episodes. Episode I began with plinian dispersal of rhyolitic fallout (Layer A) and contemporaneous emplacement of rhyolitic
Fallout and distribution of volcanic ash over Argentina following the May 2008 explosive eruption of Chaitén, Chile
[1] The major explosive eruption of Chaiten volcano, Chile, in May 2008 provided a rare opportunity to track the long-range dispersal and deposition of fine volcanic ash. The eruption followed
The millennium eruption of Hekla in February 2000
The 18th historic eruption of Hekla started on 26 February, 2000. It was a short-lived but intense event, emitting basaltic andesitic (55.5 wt% SiO2) pyroclastic fragments and lava. During the course
