The National Geology and Mining Service (Sernagomin) detected an activity , Monday on Tupungatito volcano.
It was recorded an earthquake measuring M 3.2 on the Richter scale, 25 km northwest from the main crater associated with rock fracturing, at a depth of 8.2 kilometers.
The institution said the volcano kept its level of alert Green, but with “special attention”.
The Tupungatito is one of three massifs active in the Metropolitan region, next to San Jose and Maipo. In addition, it is the number 54 in the ranking of the most dangerous volcanoes in the country.
SERNAGEOMIN said the volcano is located in the upper reaches of the Colorado River, an affluent of the Maipo River, 65 km north of Pirque. It has eight craters that have focused historical eruptive activity and are the seat of permanent fumaroles.
Historical records of eruptions are reported 19 events in 1829 and 25 events since 1646. His most recent eruption occurred in 1959-1960 with recognizable filing, issuance of a lava flow of 1.85 kilometers from long and ash falls in Argentina. The slight increase in the most recent event took place in 1986 with a small column of black ash that covered a small area of its glaciers, the agency said.
Tupungatito volcano, the northernmost historically active volcano of the central Chilean Andes, is located along the Chile-Argentina border about 90 km E of Santiago and immediately SW of the Pleistocene Tupungato volcano. Tupungatito consists of a group of 12 Holocene andesitic and basaltic andesite craters and a pyroclastic cone at the NW end of the 4-km-wide, Pleistocene dacitic Nevado Sin Nombre caldera, which is filled by glaciers at its southern end and is breached to the NW. Lava flows from the northernmost vent have traveled down the NW flank breach. Tupungatito has produced frequent mild explosive eruptions during the 19th and 20th centuries.
