Observations of tephra fall impacts from the 2011 Shinmoedake eruption, Japan [PDF]
Earth, Planets and Space, 2013 The 2011 eruption of Shinmoedake, Japan, deposited tephra across Miyazaki prefecture impacting both urban and rural environments. We provide an overview of the impacts, management and recovery of a modern city, infrastructure networks and a diverse agricultural region following this moderate sized explosive eruption, focusing on four key sectors ...

Hybrid rhyolitic eruption at Big Glass Mountain, CA, USA
Volcanica, 2021 Eruptive dynamics of the 1060 CE rhyolitic eruption of Big Glass Mountain (BGM), USA, are investigated with field observations, hydrogen isotope and H2O content analysis of pyroclastic obsidian chips and lavas.

Revised calendar date for the Taupo eruption derived by ¹⁴C wiggle-matching using a New Zealand kauri ¹⁴C calibration data set [PDF]
, 2011 Taupo volcano in central North Island, New Zealand, is the most frequently active and productive rhyolite volcano on Earth. Its latest explosive activity about 1800 years ago generated the spectacular Taupo eruption, the most violent eruption known in ...

Statistical methods for estimating tephra source and dispersal : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Statistics at Massey University, Palmerston North, New Zealand [PDF]
, 2016 Tephra refers to any pyroclastic fragments ejected from a volcanic vent and its dispersal is one of the major hazards with explosive eruptions. The attenuation of tephra fall thickness is most commonly estimated after contouring field measurements into

Natural and anthropogenic lead in sediments of the Rotorua lakes, New Zealand [PDF]
, 2010 Global atmospheric sources of lead have increased more than 100-fold over the past century as a result of deforestation, coal combustion, ore smelting and leaded petroleum. Lead compounds generally accumulate in depositional areas across the globe where,

Effects of tephra falls on vegetation: A Late‐Quaternary record from southern Italy [PDF]
Journal of Ecology, 2018 Abstract Impacts of tephra deposition on vegetation are recorded in a series of 10 high temporal resolution absolute pollen diagrams from Lago Grande di Monticchio, each diagram spanning a single tephra deposition event during the last glacial–interglacial cycle.

Decoupling climate and human impacts on the nitrogen cycle during the Irish Bronze Age
Journal of Quaternary Science, EarlyView.ABSTRACT Disentangling climate variability and human activity in past nitrogen cycling is key to understanding ecosystems. Previous studies in Ireland observed a widespread, permanent shift in terrestrial nitrogen cycling during Later Prehistory, potentially linked to intensifying land‐use.
