Relation between Central European Climate Change and Eifel Volcanism during the Last 130,000 Years: The ELSA-23-Tephra-Stack

Quaternary
The analysis of tephra layers in maar lake sediments of the Eifel shows 14 well-visible tephra during the last glacial cycle from the Holocene to the Eemian (0–130,000 yr b2k).

Geological evidence for paleotsunamis along eastern Sicily (Italy): an overview [PDF]

Natural Hazards and Earth System Sciences, 2012
We present geological evidence for paleotsunamis along the ~230 km-long coast of eastern Sicily (Italy); combining this information with historical data, we reconstruct a unique history of tsunami inundations.

Cryptotephras in the marine sediment record of the Edisto Inlet, Ross Sea: Implications for the volcanology and tephrochronology of northern Victoria Land, Antarctica

Quaternary Science Advances, 2023
We present the results of the tephrochronology study of a 14.49 m long marine sediment core (TR 17–08) collected in the Edisto Inlet, Ross Sea (Antarctica).

Big grains go far: understanding the discrepancy between tephrochronology and satellite infrared measurements of volcanic ash [PDF]

Atmospheric Measurement Techniques, 2015
There is a large discrepancy between the size of volcanic ash particles measured on the ground at least 500 km from their source volcano (known as cryptotephra) and those reported by satellite remote sensing (effective radius of 0.5–9 μm; 95% of ...

Variable preservation of the 1991 Hudson tephra in small lakes and on land

Frontiers in Earth Science
Volcanic ash (tephra) preserved in terrestrial environments and lake sediments contains information about volcanic processes and can be used to infer eruptive parameters and frequency of past eruptions, contributing to the understanding of volcanic ...

Tephrochronological evidence for the late Holocene eruption history of El Chichón Volcano, Mexico [PDF]

Geofísica Internacional, 2009
Pre-Columbian societies in the Maya Lowlands were repeatedly exposed to tephra-fall from past eruptions of El Chichón volcano, Chiapas, Mexico. Late Holocene tephra layers are well preserved in sediments of the Usumacinta-Grijalva river delta, about 150 ...

Vedde Ash constrains Younger Dryas glacier re-advance and rapid glacio-isostatic rebound on Svalbard

Quaternary Science Advances, 2022
The distal deposition of tephra from explosive volcanism has the potential to geochronologically constrain sedimentary archives and landforms.

Role of tephra in dating Polynesian settlement and impact, New Zealand

, 2004
Tephrochronology in its original sense is the use of tephra layers as time-stratigraphic marker beds to establish numerical or relative ages (Lowe and Hunt, 2001).

Possible climate preconditioning on submarine landslides along a convergent margin, Nankai Trough (NE Pacific)

Progress in Earth and Planetary Science, 2017
Submarine landslides are major agents of sediment mass transfer from the shallow to deep sea. Due to their rapid emplacement and tsunamigenic potential, such landslides are significant geohazards for society and off- and on-shore infrastructure.

Development of a multi-method chronology spanning the Last Glacial Interval from Orakei maar lake, Auckland, New Zealand [PDF]

Geochronology, 2020
Northern New Zealand is an important location for understanding Last Glacial Interval (LGI) palaeoclimate dynamics, since it is influenced by both tropical and polar climate systems which have varied in relative strength and timing.
