The dynamics of volcanic jets : Temporal evolution of particles exit velocity from shock‐tube experiments [PDF]

, 2017
Pyroclast ejection during explosive volcanic eruptions occurs under highly dynamic conditions involving great variations in flux, particle sizes, and velocities.

Enhanced Continental Weathering Contributed to the Termination of the Middle Miocene Climatic Optimum

Geophysical Research Letters, Volume 52, Issue 17, 16 September 2025.
Abstract The Middle Miocene Climatic Optimum (MMCO, ca. 17.0 to 14.7 million years (Myr) ago) is a period of global warming that could be relevant to future projections for 2100 AD. However, the mechanism of atmospheric CO2 removal during this interval, particularly, whether silicate weathering is critically involved, is currently unclear.

Investigations of the Sinus Aestuum DMD: An Anomalously Large and Compositionally Distinct Lunar Pyroclastic Deposit

Journal of Geophysical Research: Planets, Volume 130, Issue 9, September 2025.
Abstract The Sinus Aestuum (SA) dark mantle deposit (DMD) is a regional pyroclastic deposit on the central lunar near‐side. Spectra from the SA DMD are anomalous when compared to other DMDs and have been interpreted to represent a high abundance of the mineral spinel. The SA spinels are compositionally distinct compared to other lunar spinels and their

Using Lake Sediment Cores to Improve Records of Volcanism at Aluto Volcano in the Main Ethiopian Rift

Geochemistry, Geophysics, Geosystems, 2018
Aluto is a silicic volcano in central Ethiopia, flanked by two large population centers and home to an expanding geothermal power plant. Here we present data from two lake sediment cores sampled 12 and 25 km from the volcano, which record at least 24 ...

Stronger or longer: Discriminating between Hawaiian and Strombolian eruption styles [PDF]

, 2016
The weakest explosive volcanic eruptions globally, Strombolian explosions and Hawaiian fountaining, are also the most common. Yet, despite over a hundred years of observations, no classifications have offered a convincing, quantitative way of demarcating

Deformation and Gravitational Instability at Anak Krakatau (Sunda Strait, Indonesia): Insights From Direct Shear Experiments and Finite‐Element Models

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 5, May 2025.
Abstract Volcanic edifices are known to be unstable and their collapses have been observed several times in history. A collapse of island or coastal volcanoes is especially hazardous for the population living on regional shorelines due to the generation of destructive tsunami waves.

Common processes at unique volcanoes – a volcanological conundrum

Frontiers in Earth Science, 2014
An emerging challenge in modern volcanology is the apparent contradiction between the perception that every volcano is unique, and classification systems based on commonalities among volcano morphology and eruptive style.

Seismic Wavefield Change Preceding the Eruption of Shinmoe‐Dake, Kirishima Volcano, Japan, Inferred From Polarization Analysis

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 3, March 2025.
Abstract A volcanic tremor is a seismic event linked to volcanic processes, identified by ongoing ground shaking. They play a crucial role in understanding internal volcanic activities and forecasting eruptions. Detecting weak volcanic tremor signals before an eruption has remained a difficult task.

The color systematics of volcanic ashfall samples in estimating eruption sequences: a case study of the 2017–2018 eruption at Shinmoe-dake, Kirishima volcano, Southwest Japan

Earth, Planets and Space
The color of pyroclasts is fundamental, because it reflects various magma properties and eruption processes, including particle morphology, chemistry, and petrological characteristics.
