Add to ORKGThe little known Tutupaca volcano (17 degrees 01' S, 70 degrees 21' W), located at the southern end of the Peruvian arc, is a dacitic dome complex that experienced a large explosive eruption during historical times. Based on historic chronicles and our radiometric data, this eruption occurred 218 +/- 14 aBP, probably between 1787 and 1802 AD. This eruption was characterised by a large sector collapse that triggered a small debris avalanche (<1 km(3)) and an associated pyroclastic eruption whose bulk volume was 6.5-7.5x10(7) m(3). Both units were emplaced synchronously and spread onto the plain situated to the northeast of Tutupaca volcano. The spatial and temporal relationship between the debris avalanche and the pyroclastic density current...
