Typical eruption style: explosive
Chachimbiro volcano eruptions: 3740 BC (?) Last earthquakes nearby:
There are no historic eruptions. The most recent activity took place from the Pitzantzi lava dome and produced a wide-spread ash deposit that extends NW. Background:From Smithsonian / GVP volcano information:Late Pleistocene collapse of the andesitic Huanguillaro stratovolcano produced a 6.8 cu km debris-avalanche deposit and a 4-km-wide avalanche caldera open to the east that has largely been filled by lava domes, including the rhyodacitic Hugá lava dome. The avalanche deposit is overlain by three large ignimbrites and pyroclastic-flow deposits related to dome growth. The late Pleistocene-to-Holocene, NNE-trending dacitic Chachimbiro-Pucará line of lava domes includes the Pitzantzi lava dome, which erupted about 5700 years ago, producing an ash deposit that extends to the NW. Hot springs and thermal areas are present at the Chachimbiro complex. |
