Between December 1998 and April 2001, a submarine basaltic eruption occurred west of Terceira Island, Azores (Portugal) in water depths between 300 and 1,000 m. Physical evidence for the eruption was provided by the periodic occurrence of hot lava “balloons” floating on the sea surface. The balloons consisted of a large gas-filled cavity surrounded by a thin shell (a few centimetres thick). The shells of the collected balloons are composed of two layers, termed the outer layer and the inner… 
The third of five known lava balloon eruptions occurred January 1993 to March 1994 west of Socorro Island, Mexico. Large highly-vesicular basaltic scoria rose to the sea surface in pulses. Buoyant
Progressive Changes in Magma Transport at the Active Serreta Ridge, Azores
Volcanism in the Eastern Azores Plateau occurs at large central volcanoes and along subaerial and submarine fissure zones, resulting from a mantle melting anomaly combined with transtensional
The 1891 submarine eruption offshore Pantelleria Island (Sicily Channel, Italy): Identification of the vent and characterization of products and eruptive style
High‐resolution bathymetry and seafloor sampling have been used to characterize the 1891 submarine eruption of the Pantelleria volcanic complex. This submarine eruption has been documented mainly by
Exploration of the 1891 Foerstner submarine vent site (Pantelleria, Italy): insights into the formation of basaltic balloons
On October 17, 1891, a submarine eruption started at Foerstner volcano located within the Pantelleria Rift of the Strait of Sicily (Italy). Activity occurred for a period of 1 week from an eruptive
1891 AD Submarine Eruptive Processes and Geochemical Studies of Floating Scoria at Foerstner Volcano, Pantelleria
On October 17, 1891 a submarine eruption occurred at Foerstner volcano in the Straits of Sicily 4 km northwest of the island of Pantelleria, Italy. The eruption produced floating scoria bombs, or
Evolution of submarine eruptive activity during the 2011–2012 El Hierro event as documented by hydroacoustic images and remotely operated vehicle observations
Submarine volcanic eruptions are frequent and important events, yet they are rarely observed. Here we relate bathymetric and hydroacoustic images from the 2011 to 2012 El Hierro eruption with surface
Chapter 5 The magmatism of the Azores islands
Abstract Magmas in the Azores (Portugal) were erupted from both fissure zones and central volcanoes during overlapping periods. Fissure zones follow extensional trends oriented accordingly with the
Highly vesicular pumice generated by buoyant detachment of magma in subaqueous volcanism
Many submarine caldera volcanoes are blanketed with deposits of highly vesicular pumice, typically attributed to vigorous explosive activity1, 2, 3, 4. However, it is challenging to relate volcanic


Basaltic Lava Balloons Produced During the 1998–2001 Serreta Submarine Ridge Eruption (Azores)
In December 1998 a volcanic eruption started about 10 km W of Terceira Island, Azores, on the so-called Terceira Rift. The eruptive vents were located in the Serreta Submarine Ridge, at depths

Magma genesis by rifting of oceanic lithosphere above anomalous mantle: Terceira Rift, Azores
The Terceira Rift formed relatively recently (∼1 Ma ago) by rifting of the old oceanic lithosphere of the Azores Plateau and is currently spreading at a rate of 2–4mm/a. Together with the
Magma Evolution of the Sete Cidades Volcano, Sao Miguel, Azores
The Sete Cidades volcano (Sao Miguel, Azores) is situated at the eastern end of the ultraslow spreading Terceira rift axis. The volcano comprises several dominantly basaltic pre-caldera eruptions, a
Petrology, volume and age relations of alkaline and saturated peralkaline volcanics from Terceira, Azores
Four volcanoes form Terceira, one of the islands of the Azores group; three contain both basaltic and peralkaline and one only peralkaline rocks. A recently active basaltic fissure zone trends NW-SE
Floating stones off El Hierro, Canary Islands: xenoliths of pre-island sedimentary origin in the early products of the October 2011 eruption
Abstract. A submarine eruption started off the south coast of El Hierro, Canary Islands, on 10 October 2011 and continues at the time of this writing (February 2012). In the first days of the event,
Submarine basaltic volcanism: Morphometric parameters for discriminating hyaloclastites from hyalotuffs
Hyaloclastites are volcaniclastic rocks generated by non-explosive granulation of volcanic glass which takes place when basaltic magmas are quenched by contact with water; hyaloclastites are common
Two-stage fractionation history of the alkali basalt-trachyte series of Sete Cidades volcano (São Miguel Island, Azores).
A comprehensive data set of mineral and whole-rock major element compositions of the Na-alkaline lavas and pumices erupted by the Sete Cidades volcano (Sao Miguel Island, Azores) is here presented.
