Observations of eruptive activity at Santiaguito volcano, Guatemala
Journal of Volcanology and Geothermal Research, 2004Abstract The study of active vent dynamics is hindered by the difficulty of directly observing features and processes during eruptive periods. Here, we describe some recent observations of the summit dome activity of Santiaguito volcano, Guatemala, from the vantage point of its parent, Santa Maria. We have taken 12 h of digital video of activity over

Organic Compounds in Volcanic Gas from Santiaguito Volcano, Guatemala
Geological Society of America Bulletin, 1971Gas samples collected at Sapper fumarole, Santiaguito, Guatemala, on December 5, 1969, were analyzed by gas chromatography-mass spectrometry. A number of compounds were found, including saturated and unsaturated hydrocarbons, aldehydes, ketones, alcohols, aromatics, halogenated hydrocarbons, and inorganic sulfur compounds.

Nuée ardente from santiaguito volcano April 1973
Bulletin Volcanologique, 1973The largest nuee ardente eruption of Santiaguito since November 1929, occurred April 19, 1973. The nuee descended the valley of the Rio Nima II for a distance of about 4 km. The ash flow itself was restricted to the river bed, but the hot gas cloud devastated an area of more than 3 square kilometers extending hundreds of meters on both sides of the ...

Santiaguito Volcanic Dome, Guatemala
Geological Society of America Bulletin, 1972The Santiaguito volcanic dome insouthwestern Guatemala is a multiple extrusive dome that has shown constant volcanic activity since its birth in 1922. Fourteen extrusive units are mapped. Five of these are volcanic domes; the remaining nine are lava flows which generally cling to the sides of the domes.

Volcanic activity at Santiaguito volcano, Guatemala June 1968 – August 1969
Bulletin Volcanologique, 1970Information regarding activity of Santiaguito dome, in western Guatemala, for the period June 1968–August 1969, has been derived from phots taken repeatedly at strategic locations, weekly geologic observations from a nearby lookout and ten expeditions to the mountain.

Recent volcanic and fumarolic activity at Santiaguito volcano, Guatemala
Bulletin Volcanologique, 1969Santiaguito, an extrusive domal complex in southwestern Guatemala has recently exhibited renewed domal growth, as much as 50 meters vertically in the first twelve months of growth. Synchronous with this activity, near the other end of the complex 1.3 km distant, there are pyroclastic eruptions.

Mapping complex vent eruptive activity at Santiaguito, Guatemala using network infrasound semblance
Journal of Volcanology and Geothermal Research, 2011Pyroclastic-laden explosive eruptions from Santiaguito Volcano (Guatemala) are vented from the 200-m diameter Caliente Dome summit and result in a superposition of spatially extensive and temporally sustained (tens of seconds to minutes) acoustic sources.

Degassing processes during lava dome growth: Insights from Santiaguito lava dome, Guatemala
Journal of Volcanology and Geothermal Research, 2011Abstract Eruptions of intermediate magma may be explosive or effusive. The development of open system degassing has been proposed as a pre-requisite for effusion of intermediate magma, however processes leading to open system degassing are poorly understood.
