11/1994 (BGVN 19:11) Phreatic explosion in January 1994

On about 15 January 1994, Bolivar Miranda, a SERNAGEOMIN chemical engineer, observed a 5-km-high explosive column rising above Tinguiririca from a location 65 km W. A photograph taken by his son, Matías, showed a distinct white cauliflower-shaped column on a clear day. Based on the shape and growth of the column, this eruption was most likely phreatic.

Tinguiririca is composed of at least seven Holocene scoria cones west of the Chile-Argentina border constructed along a NNE-SSW fissure over an eroded Pleistocene stratovolcano. The complex was constructed during three eruptive cycles dating back to the middle Pleistocene. The latest activity produced a series of youthful small stratovolcanoes and craters, of which the youngest appear to be Tinguiririca and Fray Carlos. Constant fumarolic activity occurs within and on the NW wall of the summit crater of Tinguiririca, and hot springs and fumaroles with sulfur deposits are found on the western flanks of the summit cones. A single historical eruption from Tinguiririca was recorded in 1917.

Tinguiririca is composed of at least seven Holocene scoria cones constructed along a N-S fissure over an eroded Pleistocene stratovolcano. The central part of the chain from Tinguiririca to Fray Carlos is seen in this view. Sulfur deposits are found on the western flanks of the summit cones. A single historical eruption from Tinguiririca was recorded in 1917.

Alternating lava flows and pyroclastic deposits are exposed in the crater walls of Tinguiririca volcano. Hydrothermally altered rocks are prominent in the lower parts of the crater walls.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
