The 1723 AD violent Strombolian and phreatomagatic eruption at Irazu volcano (Costa Rica) [PDF]
The largest of the recorded historic eruptions at Irazú volcano began on February 16, 1723 and lasted until at least December 11. We here critically examine deposits of this eruption exposed on the summit of Irazú. Our reconstruction of the eruption is

New Zealand Geological Timescale 2025
New Zealand Geological Timescale 2025 (NZGT 2025) is the first comprehensive update and revision of the New Zealand Geological Timescale in a decade. The criteria used to establish age ranges of New Zealand Stages within the NZGT have been reviewed, calibrated, and revised where required against the 2023/04 International Chronostratigraphic Chart and ...

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

Re-identification of c. 15 700 cal yr BP tephra bed at Kaipo Bog, eastern North Island: implications for dispersal of Rotorua and Puketarata tephra beds. [PDF]
A 10 mm thick, c. 15 700 calendar yr BP (c. 13 100 14C yr BP) rhyolitic tephra bed in the well-studied montane Kaipo Bog sequence of eastern North Island was previously correlated with Maroa-derived Puketarata Tephra.

Early Jurassic volcanism was in the southern north Victoria Land portion of the Ferrar Large Igneous Province preceded by multiple phases of shallow‐level intrusions of Ferrar sills into the 300 m thick cover of sedimentary rocks of the Triassic‐Jurassic Victoria Group.

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