Geological Summary

Tajumulco is Guatemala's highest peak and the highest volcano in Central America. Two summits, one with a 50-70 m wide crater, lie along a NW-SE line. A lava flow from the ~4200-m-high NW summit traveled down a deep valley on the NW flank. The andesitic-dacitic volcano was constructed over the NW end of a large arcuate SW-facing escarpment of uncertain origin. Tajumulco has had several unconfirmed reports of historical eruptions. Sapper (1917) considered it to have erupted during historical time, but without accurate dates. The volcano was reported to eject many rocks, destroying houses on 24 October 1765, but this may have been a rock avalanche. Juarros reported some eruptions before 1808, and there are unlikely reports of eruptions in 1821 (or 1822), 1863, and 1893 (Incer 1988, unpublished manuscript).

Photo Gallery


Tajumulco, the highest volcano in Central America, is seen here from the NW from the slopes of Tacaná volcano, which lies along the México/Guatemala border. Conical Tajumulco volcano has twin summits, which are not distinguishable in this view. A lava flow from Tajumulco's NW summit traveled NW down a deep valley on the flank. Tajumulco has had several unconfirmed reports of historical eruptions.

A road in the relatively sparsely populated far western part of Guatemala approaches the NE side of the summit massif of Tajumulco volcano; this side has gentler slopes and higher agricultural use than the NW side. Tajumulco lies NW of the main tourist areas in the Central Highlands and is infrequently visited. The volcano is located closer to Tacaná volcano on the México/Guatemala border than it is to other Guatemalan volcanoes.

Tajumulco, the highest volcano in Central America, is seen here from the NNW. The volcano rises steeply above deeply dissected valleys cut in plutonic and Tertiary volcanic rocks. Despite its prominence, the 4220-m-high volcano is located in a relatively infrequently visited part of western Guatemala and is much less known than many other Guatemalan volcanoes. Tajumulco has had several unconfirmed reports of historical eruptions.

Tajumulco's southern flanks (left), which descend toward the Pacific coastal plain, are steeper than its northern flanks. Dioritic plutonic rocks are exposed at the base of the volcano. Tajumulco is Guatemala's (and Central America's) highest volcano, but is one of the least known of the country's major volcanoes.

MODVOLC - HIGP MODIS Thermal Alert System Using infrared satellite Moderate Resolution Imaging Spectroradiometer (MODIS) data, scientists at the Hawai'i Institute of Geophysics and Planetology, University of Hawai'i, developed an automated system called MODVOLC to map thermal hot-spots in near real time. For each MODIS image, the algorithm automatically scans each 1 km pixel within it to check for high-temperature hot-spots. When one is found the date, time, location, and intensity are recorded. MODIS looks at every square km of the Earth every 48 hours, once during the day and once during the night, and the presence of two MODIS sensors in space allows at least four hot-spot observations every two days. Each day updated global maps are compiled to display the locations of all hot spots detected in the previous 24 hours. There is a drop-down list with volcano names which allow users to 'zoom-in' and examine the distribution of hot-spots at a variety of spatial scales.
MIROVA Middle InfraRed Observation of Volcanic Activity (MIROVA) is a near real time volcanic hot-spot detection system based on the analysis of MODIS (Moderate Resolution Imaging Spectroradiometer) data. In particular, MIROVA uses the Middle InfraRed Radiation (MIR), measured over target volcanoes, in order to detect, locate and measure the heat radiation sourced from volcanic activity.
