Robust multi-year climate impacts of volcanic eruptions in decadal prediction systems [PDF]

, 2020
Major tropical volcanic eruptions have a large impact on climate, but there have only been three major eruptions during the recent relatively well-observed period.

Assessment of directional accuracy of GNSS-Acoustic measurement using a slackly moored buoy

Progress in Earth and Planetary Science, 2019
We assessed the positioning accuracy of GNSS-Acoustic (GNSS-A) measurement using a slackly moored buoy. A key feature of real-time buoy-based GNSS-A measurement is that positioning must be performed via single ranging from an arbitrary observation ...

Predictability of Volcano Eruption: lessons from a basaltic effusive volcano [PDF]

, 2003
Volcano eruption forecast remains a challenging and controversial problem despite the fact that data from volcano monitoring significantly increased in quantity and quality during the last decades.This study uses pattern recognition techniques to ...

The Influences of Tropical Volcanic Eruptions with Different Magnitudes on Persistent Droughts over Eastern China

Atmosphere, 2020
In this study, the influences on persistent droughts over Eastern China from tropical volcanic eruptions with three categories of magnitudes, i.e., 25 Tg, 50 Tg, and 100 Tg, were investigated through three groups of volcanic sensitivity experiments based

Precise aftershock distribution of the 2019 Yamagata-oki earthquake using newly developed simple anchored-buoy ocean bottom seismometers and land seismic stations

Earth, Planets and Space, 2022
An earthquake with a magnitude of 6.7 occurred in the Japan Sea off Yamagata on June 18, 2019. The mainshock had a source mechanism of reverse-fault type with a compression axis of WNW–ESE direction.

Evaluation of the favorability of faults to slip: the case of the 2024 Noto Peninsula earthquake

Earth, Planets and Space
The 2024 Noto Peninsula earthquake (M 7.6) occurred at a depth of approximately 15 km in the eastern part of Noto Peninsula. The high dip angle faults (50–60°) in this area were formed by the extensional stress field during the formation of the Japan Sea.

Charge State Influence on Stability and Isomerism in Dehydrogenated PAHs: Insights from Anthracene, Acridine, and Phenazine

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
The ionization of anthracene, acridine, and phenazine has been explored, along with the removal of one and two hydrogen atoms, to provide valuable information for astrochemists and to understand the behavior of the resulting structures and their electronic reorganization. Abstract In this study, we systematically explored the stability and isomerism of

Stratosphere troposphere coupling: the influence of volcanic eruptions [PDF]

, 2011
Stratospheric sulfate aerosols produced by major volcanic eruptions modify the radiative and dynamical properties of the troposphere and stratosphere through their reflection of solar radiation and absorption of infrared radiation. At the Earth's surface,

Tambora 1815 as a test case for high impact volcanic eruptions: Earth system effects [PDF]

, 2016
The eruption of Tambora (Indonesia) in April 1815 had substantial effects on global climate and led to the ‘Year Without a Summer’ of 1816 in Europe and North America. Although a tragic event—tens of thousands of people lost their lives—the eruption also

High‐Titanium Zircon Rims in Rhyolite – A Reflection of Adiabatic Ascent?

Geological Journal, EarlyView.
The ascent of granitic magma from source to emplacement is rapidly achieved through dyking, resulting in negligible heat loss to the surrounding wallrock (i.e., adiabatic). Zircon growth during ascent can record the changing magma conditions including adiabatic cooling and heating, resulting in high titanium rims on low titanium cores without ...
