The first direct evidence that patterns of basaltic eruptive activity may be very similar on Io and Earth was seen on November 26, 1999, when the solid-state imaging system on board the Galileo spacecraft obtained high-resolution images of a fissure eruption taking place in one of the calderas of the Tvashtar Catena complex. We analyzed the dynamics of the fissure eruption from the morphology of the lava fountains and pyroclastic deposits and derived an estimate of the eruption rate. Our best… 
The summer 1997 eruption at Pillan Patera on Io: Implications for ultrabasic lava flow emplacement
Galileo data and numerical modeling were used to investigate the summer 1997 eruption at Pillan Patera on Io. This event, now defined as “Pillanian” eruption style [Keszthelyi et al., this issue],
Imaging of volcanic activity on Jupiter's moon Io by Galileo during the Galileo Europa Mission and the Galileo Millennium Mission
The Solid-State Imaging (SSI) instrument provided the first high- and medium-resolution views of Io as the Galileo spacecraft closed in on the volcanic body in late 1999 and early 2000. While each
A model for large‐scale volcanic plumes on Io: Implications for eruption rates and interactions between magmas and near‐surface volatiles
[1] Volcanic plumes deposit magmatic pyroclasts and SO2 frost on the surface of Io. We model the plume activity detected by Galileo at the Pillan and Pele sites from 1996 to 1997 assuming that
Valles Marineris tectonic and volcanic history inferred from dikes in eastern Coprates Chasma
Magmatic dikes have been proposed to have weakened and fractured the crust, allowing the formation of Valles Marineris. Hence, dikes were studied in the region of eastern Coprates Chasma in an area


Ascent and eruption of basaltic magma on the earth and moon
Geological and physical observations and constraints are applied to the development of a model of the ascent and emplacement of basaltic magma on the earth and moon. Mathematical models of the nature
Ascent and Eruption of Magmas on Io: Application to Pele
Pele is one of the most active volcaniccentres on Io. Unlike other Ionian volcanoes imaged by boththe Voyager and Galileo spacecraft, eruptions at this locationappear to be short lived and associated
The fate of pyroclasts produced in explosive eruptions on the asteroid 4 Vesta
Abstract— We evaluate the consequences of explosive activity having taken place during volcanic eruptions on the differentiated asteroid 4 Vesta, which is the likely parent body of the
Nature of Local Magma Storage Zones and Geometry of Conduit Systems Below Basaltic Eruption Sites: Pu'u 'O'o, Kilauea East Rift, Hawaii, Example
The fluid dynamics of the well-documented eruptive episodes at Pu'u 'O' o, Kilauea (Wolfe et at., 1987) are used to investigate quantitativeely the size and shape of the shallow conduit system
Dark ring in southwestern Orientale Basin: Origin as a single pyroclastic eruption
[1] A large, 154 km diameter dark annular ring, located in the southwestern part of the Orientale Basin along the Montes Rook ring, was first discovered and documented in Soviet Zond 8 images.
Galileo at Io: results from high-resolution imaging.
During late 1999/early 2000, the solid state imaging experiment on the Galileo spacecraft returned more than 100 high-resolution images of volcanically active Io, observing an active lava lake, an active curtain of lava, active lava flows, calderas, mountains, plateaus, and plains.
Dynamics of a confined lava flow on Kilauea volcano, Hawaii
This paper presents a new method of analysing lava flow deposits which allows the velocity, discharge rate and rheological properties of channelled moving lavas to be calculated. The theory is
The Laki (Skaftár Fires) and Grímsvötn eruptions in 1783–1785
The Laki (Skaftár Fires) fissure eruption in southern Iceland lasted for eight months during 1783 to 1784, and produced one of the largest basaltic lava flows in historic times (14.7±1.0 km3). In
Mountains and Calderas on Io: Possible Implications for Lithosphere Structure and Magma Generation
Abstract The combination of Voyager images and newly acquired Galileo images with low illumination and resolutions ranging from 2 to 6 km/pixel now allows determination of the global distribution of
