Historical Volcanic Eruptions Mitigated the Expected Rapid Arctic Sea Ice Decline Prior to 2000

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Arctic sea ice has declined at sharply contrasting rates over the past four decades—modest before 2000 and rapid thereafter. Using observational and model evidence, we show that large tropical volcanic eruptions can trigger decade‐long Arctic sea ice recoveries, and that without the 1982 El Chichón and 1991 Pinatubo eruptions, Arctic sea ice ...

Volcanic History and Eruption Processes of Blue Lake Crater, Tongariro [PDF]

, 2014
Blue Lake Crater (BLC) is a volcanic crater lake situated on the northern end of the Tongariro Volcanic Centre (TgVC) and is one of at least 11 vents that have been active since c. 25 ka.

Rapid changes of the lava‐delta coastlines formed by the 2021 volcanic eruption on La Palma, Canary Islands

Earth Surface Processes and Landforms, Volume 51, Issue 6, June 2026.
A new coastline formed during the 2021 eruption of La Palma quickly eroded, becoming crenellated and with pocket beaches, then retreated more gradually as resistant interiors of the lava were exposed. In contrast, a second thicker lava delta changed more gradually, highlighting the importance of lithology to coastal erosion.

Volcanology of tuff rings at Kellyville, Onewhero and Bombay, South Auckland Volcanic Field [PDF]

, 2011
The South Auckland volcanic field hosts 82 volcanic centres over an area of approximately 300 km2 in the Pukekohe, Bombay, Tuakau, Pukekawa and Onewhero regions. The intraplate, monogenetic basaltic volcanic field was active between 1.59 and 0.51 Ma, and

An Overview of Tsunami Hazards in the Southwest Pacific Ocean

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
The southwest Pacific region is geologically complex and exhibits all the principal causes of tsunami generation. While contemporary events and historical catalogs indicate that trans‐Pacific tsunamis have affected this area (∼18% of tsunamis reported globally), it is unique in that a large part of the tsunami effects over the ∼200‐year historical ...

Fracture mechanics of volcanic eruptions [PDF]

, 2009
Seismology is a key tool in the forecasting of volcanic eruptions. The onset of an eruption is often preceded and accompanied by an increase in local seismic activity, driven by fracturing within the edifice.

Integrating Olivine Diffusion Chronometry With Monitoring Data to Decipher the Magma Dynamics at the Submarine Fani Maoré Volcano

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Monitoring data are critical for understanding volcanic unrest and eruption, but they often lack the ability to constrain the pre‐eruptive magma processes. As such, an increasing number of studies couple monitoring data with petrological tools to obtain insights into the causes and durations of magmatic processes. The 2018–2020 eruption of the

Forced and free waves of simulated volcanic meteo-tsunamis in the South China Sea

npj Natural Hazards
Volcanic meteo-tsunamis (VMTs) are rare, devastating phenomena first recognised after the 1883 Krakatau eruption in Indonesia and recently quantified following the 2022 Hunga Tonga-Hunga Ha’apai volcanic eruption in the Kingdom of Tonga.

The chronology of the Aegean late bronze age with special reference to the "Minoan” eruption of Thera [PDF]

, 2002
The chronology of the Aegean Late Bronze Age is a vigorously contested area of archaeological study, with "high" and "low" schemes emerging over the last three decades.

Eruption Dynamics and Hydrological Implications of Basaltic Volcanic Centres at Lake Taupo [PDF]

, 2010
The Taupo Volcanic Centre (TVC) is a major rhyolite centre within the Taupo Volcanic Zone, yet a small volume of the centre is comprised of monogenetic basalt volcanoes. Four TVC basalts that lie north of Lake Taupo have been examined in this study: the
