Radiometric Constraints on the Timing, Tempo, and Effects of Large Igneous Province Emplacement

open access: yesGeophysical Monograph Series, Page 27-82., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Geodetic monitoring of the Changbaishan volcano activity and its relationship with earthquakes, 1999–2017

open access: yesGeodesy and Geodynamics, 2021
The major earthquakes often trigger unrest of surrounding volcanic magma chambers. In recent years, three major earthquakes occurred around the Changbaishan volcano, but it was unclear whether these earthquakes triggered the unrest of the magma chamber ...

Physical modeling of magma chamber of slamet volcano by means of satellite gravimetric data

open access: yesCommunications in Science and Technology, 2022
Slamet Volcano (3,432 m) is the highest volcano in Central Java, Indonesia, with a weak explosive type of eruption compared to other active volcanoes. Designing the magma chamber model may help reveal the characteristics of Slamet Volcano.

Constraints on magma storage conditions based on geodetic volume change and erupted magma volume and application to the 2011 and 2018 eruptions at Kirishima Shinmoe-dake volcano, Japan

open access: yesEarth, Planets and Space, 2023
We investigated magma storage conditions prior to the 2011 and 2018 eruptions at Kirishima Shinmoe-dake volcano in Japan based on the relationship between geodetic volume change of magma chamber and erupted magma volume.

Pre-eruption magmatic processes and magma plumbing system at Hachijo-Nishiyama volcano, Izu–Bonin arc, Japan

open access: yesEarth, Planets and Space, 2023
Nishiyama volcano on Hachijojima Island is an active basaltic volcano located in the Izu–Bonin arc. In this study, petrological and geochemical analyses were conducted on mafic lavas and pyroclastics to understand the magma plumbing system and pre ...

The dynamics of dual-magma-chamber system during volcanic eruptions inferred from physical modeling

open access: yesEarth, Planets and Space, 2021
A magma plumbing system with dual magma chambers beneath active volcanoes is commonly observed through petrological and geophysical measurements. This paper developed a physical model for the dynamics of a dual-magma-chamber system during volcanic ...

Using Apatite to Track Volatile Evolution in the Shallow Magma Chamber below the Yonaguni Knoll IV Hydrothermal Field in the Southwestern Okinawa Trough

open access: yesJournal of Marine Science and Engineering, 2023
The Yonaguni Knoll IV is an active seafloor hydrothermal system associated with submarine silicic volcanism located in the “cross back-arc volcanic trail” (CBVT) in the southwestern Okinawa Trough.

The Rustenburg Layered Suite formed as a stack of mush with transient magma chambers

open access: yesNature Communications, 2021
The Rustenburg Layered Suite of the Bushveld Complex, South Africa, has long been regarded as a textbook result of fractional crystallization from a melt-dominated magma chamber.

Orientation of the eruption fissures controlled by a shallow magma chamber in Miyakejima

open access: yesFrontiers in Earth Science, 2016
Orientation of the eruption fissures and composition of the lavas of the Miyakejima volcano indicate tectonic influence of a shallow magma chamber on the distribution of eruption fissures.
