Major‐Minor‐Trace Element Analyses and Oceanographic Modeling Confirms Circumpolar Transport of the 1962 Protector Shoal Pumice Raft

Journal of Geophysical Research: Oceans, Volume 130, Issue 12, December 2025.
Abstract Pumice rafts derived from submarine eruptions can remain afloat for months or even years, traveling thousands of kilometers on ocean currents. These natural phenomena disperse marine organisms and provide important evidence for submarine volcanism yet are not fully understood.

A Cryptotephra Layer in Sediments of an Infilled Maar Lake from the Eifel (Germany): First Evidence of Campanian Ignimbrite Ash Airfall in Central Europe

Quaternary
We analyzed mineralogical characteristics, and major as well as rare earth element concentrations, from a cryptotephra layer in sediments of the infilled maar of Auel (Eifel, Germany).

Contemporary carbon fluxes do not reflect the long-term carbon balance for an Atlantic blanket bog [PDF]

, 2017
Peatlands are one of the largest terrestrial stores of carbon. Carbon exchange in peatlands is often assessed solely by measurement of contemporary fluxes; however, these fluxes frequently indicate a much stronger sink strength than that measured by the ...

The Te Puninga Fault, Hauraki Plains: a new seismic source in the low seismicity northern region of New Zealand

New Zealand Journal of Geology and Geophysics, Volume 68, Issue 4, Page 609-627, December 2025.
ABSTRACT In this study, we provide the first field‐based assessment of the seismic potential of the Te Puninga Fault, Hauraki Plains, Waikato region. Initially considered to be part of the nearby Kerepehi Fault, our new mapping and field data suggest the Te Puninga Fault is independent.

An ashy septingentenarian: the Kaharoa tephra turns 700 (with notes on its volcanological, archaeological, and historical importance) [PDF]

, 2014
Most of us are aware of the basaltic Tarawera eruption on 10th June 1886: the high toll on life (~120 people), landscape devastation, and loss of the Pink and White Terraces.

The 600 yr eruptive history of Villarrica Volcano (Chile) revealed by annually laminated lake sediments [PDF]

, 2014
Lake sediments contain valuable information about past volcanic and seismic events that have affected the lake catchment, and they provide unique records of the recurrence interval and magnitude of such events.

A tephrostratigraphic investigation of the continuously varved Holocene Boreal lake Nautajärvi, Finland, provides precise age estimate for Lairg A/Hekla 5 eruption

Journal of Quaternary Science, Volume 40, Issue 7, Page 1212-1229, October 2025.
ABSTRACT Numerous cryptotephra layers originating from Icelandic volcanoes and further afield have reached Northern Europe during the Holocene. Refining the precise timing and the relative frequency of local and distal eruptions requires well‐resolved continuous sediment archives. Lake Nautajärvi is located in central‐southern Finland (61°48′ N, 24°41′

First discovery of Holocene Alaskan and Icelandic tephra in Polish peatlands [PDF]

, 2017
Despite the discovery of cryptotephra layers in over 100 peatlands across northern Europe, Holocene cryptotephra layers have not previously been reported from Polish peatlands.

Offshore Record of Explosive Volcanic Eruptions in the Southern Part of the Panamá Basin During the Past 10 Myr: 1. Tephrostratigraphy, Cross‐Correlations and Geochemical Characterization

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 9, September 2025.
Abstract Northern Andean volcanism is characterized by an intense Quaternary activity, whose onshore deposits have partly covered Mio‐Pliocene products associated with the early development of the arc, making it difficult to obtain an exhaustive catalog of past eruptions.
