Characterising the wind-advected medial fall deposit from fissure 8 fountaining during the 2018 lower East Rift Zone eruption, Kīlauea
The 2018 eruption on the lower East Rift Zone, Hawaii, involved the opening of 24 fissures before the eruption focussed on a single point source,...

Evolving shallow conduit revealed by tremor and vent activity observations during episodic lava fountaining of the 2021 Geldingadalir eruption, Iceland
Cyclic behaviour is observed in volcanic phenomena ranging from caldera collapses to explosions, spattering or lava fountaining. The repeating...

Total grain size distribution of an intense Hawaiian fountaining event: case study of the 1959 Kīlauea Iki eruption
The 1959 eruption of Kīlauea Iki on the Island of Hawai’i is a principal example of powerful Hawaiian fountaining. Over 36 days (including repose...

Infrasound observations and constraints on the 2018 eruption of Kīlauea Volcano, Hawaii
The 2018 eruption of Kīlauea Volcano was a dynamic event involving explosions, collapses, and fountaining at multiple vents spread over tens of...

The 23–24 March 2021 lava fountain at Mt Etna, Italy
In 2021, more than 50 paroxysmal episodes occurred at the South-East Crater (SEC) of Mt Etna, Italy. The 23–24 March lava fountain was one of the...

Acoustic observations of lava fountain activity during the 2021 Fagradalsfjall eruption, Iceland
The 2021 eruption within the Fagradalsfjall volcanic system in Iceland provided a rare opportunity to record acoustic data generated by a basaltic...

Brittle fragmentation by rapid gas separation in a Hawaiian fountain
Brittle fragmentation, generating small pyroclasts from magma, is a key process determining eruptive style. How low-viscosity magma fragments within...
-
Explosive Eruption Styles, Columns, and Pyroclastic Fallout Deposits
In this chapter, we consider the range of volcanic explosive eruption styles, from the smallest and least intense to the largest and most intense...

Variability of ash deposits at Piton de la Fournaise (La Reunion Island): insights into fragmentation processes at basaltic shield volcanoes
It is commonly accepted that effusive activity emplaces the main emitted magmatic volume in basaltic shield volcanoes. At Piton de La Fournaise (La...

Controls on juvenile ash morphologies in lava fountains: insights from laboratory experiments
Hawaiian lava fountains produce a wide variety of pyroclasts, including achneliths, i.e., fluidal juvenile fragments. These range from nearly perfect...

Intricate episodic growth of a Hawaiian tephra deposit: case study of the 1959 Kīlauea Iki eruption
The 1959 Kīlauea Iki eruption on Hawai’i generated a succession of fountains, most reaching hundreds of meters high. The 16 episodes of fountaining...

Tertiary monogenetic volcanism in the Gabal Marssous, Bahariya Depression, Western Desert, Egypt: implication for multi-phases, mafic scoria cone suite related to Red Sea rift in the Afro-Arabian realm
An integrated stratigraphic, sedimentological, volcanological, and geochemical studies were conducted for the first time on the eruptive products of...

Monogenetic to Polygenetic Mafic Volcanism
The mafic back-arc volcanism, uncommon in the Andean Central Volcanic Zone, is represented in the Puna region by late Miocene to Quaternary small...

Fragmentation Processes in Magmas and Volcanic Rocks
In this chapter, we consider the many processes by which magma and volcanic rock can be fragmented. This comprehensive review describes the...
-
Magma storage and transport timescales for the 1959 Kīlauea Iki eruption and implications for diffusion chronometry studies using time-series samples versus tephra deposits
Complex crystal cargo in basaltic eruptions has the potential to yield diverse insights on pre- and syn-eruptive timescales of magma storage and...

High variability of interaction energy between volcanic particles: implications for deposit stability
Landslides on the flanks of stratovolcanoes can significantly modify the structure of the volcano. Macroscopic factors that determine the stability...
-
Magma fragmentation: a perspective on emerging topics and future directions
The breaking apart of magma into fragments is intimately related to the eruptive style and thus the nature and footprint of volcanic hazards. The...

Pre-existing ground cracks as lava flow pathways at Kīlauea in 2014
In 2014, the Pāhoa lava flow at Kīlauea, on the Island of Hawaiʻi (USA), entered a string of pre-existing meter-width ground cracks in the volcano’s...

Submarine lava deltas of the 2018 eruption of Kīlauea volcano
Hawaiian and other ocean island lava flows that reach the coastline can deposit significant volumes of lava in submarine deltas. The catastrophic...
