    Compaction of Hyaloclastite from the Active Geothermal System at Krafla Volcano, Iceland by Guðjón H. Eggertsson, Jackie E. Kendrick, Joshua Weaver, Paul A. Wallace, James E. P. Utley, John D. Bedford, Michael J. Allen, Sigurður H. Markússon, Richard H. Worden, Daniel R. Faulkner, Yan Lavallée

    Published 2020-01-01
    “…Hyaloclastites commonly form high-quality reservoir rocks in volcanic geothermal provinces. Here, we investigated the effects of confinement due to burial following prolonged accumulation of eruptive products on the physical and mechanical evolution of surficial and subsurface (depths of 70 m, 556 m, and 732 m) hyaloclastites from Krafla volcano, Iceland. …”

    Multivariate Analysis, Mass Balance Techniques, and Statistical Tests as Tools in Igneous Petrology: Application to the Sierra de las Cruces Volcanic Range (Mexican Volcanic Belt) by Fernando Velasco-Tapia

    Published 2014-01-01
    “…As an example, in this work a statistical and quantitative scheme is applied to analyze the geochemical features for the Sierra de las Cruces (SC) volcanic range (Mexican Volcanic Belt). In this locality, the volcanic activity (3.7 to 0.5 Ma) was dominantly dacitic, but the presence of spheroidal andesitic enclaves and/or diverse disequilibrium features in majority of lavas confirms the operation of magma mixing/mingling. …”

    Sporadic E responds to the 2022 Tonga volcano eruptions recorded by the Meridian Project by YangYi Sun, Tao Yu, Jin Wang, Chi Long

    Published 2025-01-01
    “…In this study, ionosonde observations over Fuke (19.5°N, 109.1°E), Wuhan (30.5°N, 114.4°E), and Mohe (53.5°N, 122.3°E) were analyzed to demonstrate the responses of the sporadic E () to the severe atmospheric disturbances caused by the Tonga volcanic eruptions on January 15, 2022. The most prominent signature was the disappearance of the layer after ~10:00 UT over Wuhan and Fuke, which was attributed to the vertical drift caused by the eruptions. …”
