Stratigraphy and chronology of a 15ka sequence of multi-sourced silicic tephras in a montane peat bog, eastern North Island, New Zealand. [PDF]
, 1999 We document the stratigraphy, composition, and chronology of a succession of 16 distal, silicic tephra layers interbedded with lateglacial and Holocene peats and muds up to c. 15 000 radiocarbon years (c.

Atmosphere, 2021 Vulcanian eruptions (short-lived explosions consisting of a rising thermal) occur daily in volcanoes around the world. Such small-scale eruptions represent a challenge in numerical modeling due to local-scale effects, such as the volcano’s topography ...

Residential building and occupant vulnerability to tephra fall [PDF]
Natural Hazards and Earth System Sciences, 2005 Plinian and subplinian volcanic eruptions can be accompanied by tephra falls which may last hours or days, posing threats to people, buildings and economic activity. Numerous historical examples exist of tephra damage and tephra casualties.

Ice core evidence for a second volcanic eruption around 1809 in the Northern Hemisphere [PDF]
, 2006 A volcanic signal observed in ice cores from both polar regions six years prior to Tambora is attributed to an unknown tropical eruption in 1809. Recovery of dacitic tephra from the 1809 horizon in a Yukon ice core (Eclipse) that is chemically distinct ...

Reliability of Total Grain-Size Distribution of Tephra Deposits
Scientific Reports, 2019 Total Grain-Size Distribution (TGSD) of tephra deposits is key to the characterization of explosive volcanism, plume-dispersal modeling, and magmatic fragmentation studies. Nonetheless, various aspects that includes deposit exposure and data fitting make

Introduction to the landscapes and soils of the Hamilton Basin [PDF]
, 2010 The Hamilton Basin area is characterised by four main landscape units or landforms as depicted in the block diagrams below (McCraw, 1967, 2002; Bruce, 1979; Selby and Lowe, 1992), and these provide a soil-landscape model to predict the soil ...

Hiroshi Machida −respected tephrochronologist, teacher, leader [PDF]
, 2011 Professor Emeritus Hiroshi Machida (Hiroshi hereafter) is the leading tephrochronologist of his generation in Japan. Perhaps more than any other geoscientist from Japan, Hiroshi carried the insights and advances of tephra studies and their application in
