Abstract: During volcanic eruptions, ash (tephra) is instantaneously deposited across the landscape as a blanket of material. Over time, it is buried, preserving a record of past volcanism. In countries like New Zealand, where volcanic eruptions have occurred consistently throughout geologic history, tephra(s) found in the geological record contain a wealth of information including the size, style, and frequency of events. Identifying the ash, and unlocking it’s story, is key to uncovering the characteristics of past eruptions. In this seminar I will guide us through the advancement of tephra studies in New Zealand in recent years, from geochemical fingerprinting and dating of volcanic ash deposits, through to identifying hidden ash, cryptotephra, which cannot be seen with the naked eye.
