Abstract

Information 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.

Activity continues at the principal Caliente vent. Ash, bombs and gas eruptions have been interspersed with repeated extrusion and blasting away of small plug domes. At the subsidiary vent, El Brujo, dome extrusion and accompanying avalanching, so prominent in 1967–68, has declined since late 1968. The minimum volume of the El Brujo dome (formed since 1966) is estimated to be 8.5 × 10⁶ m³.
