Quick Summary

Sigurður Þórarinsson was an Icelandic scientist who founded the science of tephrochronology. This method of age determination uses layers of volcanic ash (tephra) as time-stratigraphic markers. Due to Iceland's numerous volcanic eruptions, Þórarinsson was able to create a detailed chronology of geological and archaeological events there. His work allowed for a thorough study of climate changes in Iceland and the impact of agriculture on its ecology.1
