Abstract
Tacana Volcano is at the northwestern end of the Central American volcanic belt. It has erupted silicic andesites of calc-alkalic affinity and moderate K-enrichment. Tacana has no record of magmatic eruptive activity in historic times, but has shown a pattern of brief periods of fumarolic and phreatic activity spaced one quarter to half a century apart. The latest started on December 1985 and continued at the time of preparation of this paper (1988). Analysis of ashes indicates that the eruptions were phreatic. Magmatic activity is likely in the future and may follow scenarios based on similar volcanoes (Arenal, Santa Maria, St. Helens) and result in considerable hazards. A photogeologic map and two volcanic hazard maps are presented. -from English summary
