Expanding the Tephrochronological Record in the Alps: Discovery of the Laacher See Tephra in Lake Plansee (Austria)

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 12, December 2025.
Abstract We present the first documented occurrence of the Laacher See tephra (LST) in the Eastern Alps, identified in lake Plansee, Austria. The LST is a key chronostratigraphic marker for correlating and dating Late Glacial sedimentary archives. This discovery was made by progressively narrowing down observational limits from rough estimates of ...

Synchronisation of sedimentary records using tephra : a postglacial tephrochronological model for the Chilean Lake District [PDF]

, 2016
Well-characterised tephra horizons deposited in various sedimentary environments provide a means of synchronising sedimentary archives. The use of tephra as a chronological tool is however still widely underutilised in southern Chile and Argentina.

Facies Characterization and Volcanic Source Assignment of Marine Tephra Deposits Around São Miguel Island, Azores Archipelago

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 12, December 2025.
Abstract Long‐term tephrostratigraphies of volcanic islands such as the Azores are often limited to young and incomplete subaerial records. Here, we present a Pleistocene‐Holocene marine tephra archive around the eastern islands of the Azores based on 22 marine gravity cores.

Sedimentary record of submarine gravity‐flow events in the southern Ryukyu forearc during the last 200 000 years: Archive of mega‐earthquakes and tsunamis

Sedimentology, Volume 72, Issue 7, Page 2323-2360, December 2025.
ABSTRACT Despite high convergence velocity, the southern Ryukyu subduction has relatively low and sparse instrumental seismicity, in contrast with the Yaeyama Islands, hit by huge tsunamis over the last few thousand years. This study explores the potential of deep marine sediments to record past large earthquakes and tsunamis.

Tephra without borders: Far-reaching clues into past explosive eruptions

Frontiers in Earth Science, 2015
This review is intended to highlight recent exciting advances in the study of distal (>100 km from the source) tephra and cryptotephra deposits and their potential application for volcanology.

Connecting and dating with tephras: principles, functioning, and application of tephrochronology in Quaternary research [PDF]

, 2015
Tephrochronology, the characterisation and use of volcanic-ash layers as a unique chronostratigraphic linking, synchronizing, and dating tool, has become a globally-practised discipline of immense practical value in a wide range of subjects including ...

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′

Tephrochronology of the central Mediterranean MIS 11c interglacial (∼425–395 ka): New constraints from the Vico volcano and Tiber delta, central Italy

, 2020
Through a systematic integrated approach, which combined lithostratigraphic, geochronological and geochemical analyses of tephra from near-source sections of the peri-Tyrrhenian volcanoes and mid to distal settings, here we provide an improved ...
