Its latest explosive activity about 1800 years ago generated the spectacular Taupo eruption, the most violent eruption known in the world in the last 5,000 years.The Taupo eruption is a key event for the international volcanological community because the resultant deposits, well preserved and easily accessible, have been the subject of intense study in the fields of physical volcanology, volcanic hazard analysis, and volcanic petrology.Accelerator mass spectrometry is not dependent upon the radioactive decay.

Dr Hogg used Hogg A, Lowe D, Palmer J, Boswijk G, Ramsey C. Definitive high-precision calendar date for the Taupo eruption derived by wiggle-match dating using a New Zealand kauri-derived calibration curve.The core instruments of the Electron Microscope Facility are the Hitachi S-4700 Field Emission Scanning Electron Microscope (SEM) with Quorum Technologies Cryo-system, and the Philips CM30 High Resolution Transmission Electron Microscope (TEM).Both have x-ray analytical capability for elemental analysis.The SEM system allows high magnification imaging and elemental analysis of small samples including hydrated materials.Sample type may range from bacteria and plant material to metal alloys.DR CHRISTINE PRIOR In conventional radiocarbon dating, you’re measuring the presence of the C-14 when you measure the radioactive decay.
