Volcanic activity at Santiaguito volcano, 1976–1984
1987Santiaguito volcano, active for the past 62 yr, has produced almost 1 km 3of compositionally uniform, soda-rich, calc-alkalic dacite lava that is preserved in 22 distinct extrusive units. The volcanic activity has consisted of endogenous extrusions, block-lava flows, Merapi-type block and ash flows, vertical pyroclastic eruptions, and lahars.

Abstract We implement an infrasound semblance technique to identify acoustic sources originating from volcanic vents and apply the technique to the generally low-amplitude infrasound (

Nuée ardente eruption from the foot of a dacite lava flow, Santiaguito volcano, Guatemala
Bulletin Volcanologique, 1976Field observations of the zone affected by a small nuee ardente which issued from Santiaguito volcanic dome on 15 September 1973, have established clearly that the eruption came from the distal end of a blocky dacite lava flow. This emphasizes that such eruptions need not be related to an underground magma storage.

Abstract Broadband seismic observations made near the active vent at Santiaguito provide constraints on changing pressures inside the edifice. During January 2009 we recorded episodic ultra-long period signals (ULPs, > 30 s) that were coincident with eruptive activity centered on the active El Caliente vent.

Pattern and mechanism of volcanic activity at the Santiaguito Volcanic Dome, Guatemala
Bulletin of Volcanology, 1973Santiaguito volcano has shown a continuous slow extrusion of dacite lava since 1922. In the 50 years of activity there have been four periods of abnormally high extrusion rates, interspersed by periods of little magma production. The type of activity shown by the volcano has been varied and crudely cyclic.

Abstract Data from a December 2008–January 2009 seismometer deployment show substantial variation in seismic signal characteristics among different sites and eruptive events at Santiaguito volcano. A station on one of the inactive domes typically records higher amplitudes and a more peaked spectrum than does another station closer to the vent on lower
