Assessing the Environmental Consequences of the Generation and Alteration of Mafic Volcaniclastic Deposits During Large Igneous Province Emplacement

open access: yesGeophysical Monograph Series, Page 117-131., 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.

Impact and Inspiration of Tonga volcanic Eruption in 2022 [PDF]

open access: yesE3S Web of Conferences, 2023
People have been puzzled by the problem of volcanic eruptions since ancient times. Because volcanic eruptions are difficult to predict accurately, if people can't take some precautions in advance, sometimes volcanic eruptions will cause great injuries ...

An Investigation on the Ionospheric Response to the Volcanic Explosion of Hunga Ha’apai, 2022, Based on the Observations from the Meridian Project: The Plasma Drift Variations

open access: yesRemote Sensing, 2023
The Hunga Ha’apai volcano eruption (20.536°S, 175.382°W in Tonga) reached its maximum outbreak on 15 January 2022, at 04:15 UT, leading to huge oceanic fluctuations and atmospheric disturbances. This study focuses on the response of the ionosphere to the

Vesiculation and Quenching During Surtseyan Eruptions at Hunga Tonga‐Hunga Ha'apai Volcano, Tonga [PDF]

open access: yesJournal of Geophysical Research: Solid Earth, 2018
AbstractSurtseyan eruptions are shallow to emergent subaqueous explosive eruptions that owe much of their characteristic behavior to the interaction of magma with water. The difference in thermal properties between water and air affects the cooling and postfragmentation vesiculation processes in magma erupted into the water column.
