The value of historical documents for risk reduction: the 1600 Huaynaputina Eruption (Peru)

Abstract

On the 14th of February of 1600, one of the most explosive eruptions occurred in historical times in South America (VEI 6) plunged the city of Arequipa (Peru) and surrounding villages into a severe crisis, with long lasting dramatic economic consequences. The eruption was produced by the Huaynaputina dacitic stratovolcano (16º37’S-70º51’W), although many historical sources attribute the activity to the volcano of Arequipa or Omate, among others. This eruption also produced alterations in the global climate, between 1601 and 1603. The aim of this research is to demonstrate how historical documents and an adequate working methodology, may aid to reduce disasters.
