    Mattos, Seth Taylor2020

    <p>Mount St. Helens (MSH) volcano in southwestern Washington has intermittently erupted dacitic products for the last 40,000 years. On limited occasions, the volcano has produced andesite lava flows, and during one short-lived period, basaltic lava flows. This time interval has been termed the …

    SMITH, DIANE RUTHRice University1984

    Mount St. Helens volcano (Washington, USA) has been characterized by four eruptive periods during the last 2200 years. Eruptive products include a wide spectrum of rock types including basaltic to andesitic lavas, andesitic to dacitic pyroclastic flows and tephra, and dacite domes. The major and …

  7. High speed geological boundary layer flows

    Prisco, David M.University of Illinois at Urbana-Champaign2011

    The following work is an investigation of high speed boundary layers in geological flows. In particular, it focuses on meteorite impact structures of the Martian double-layer ejecta (DLE) type and the Mount St. Helens eruption of 1980 which was hypothesized to be an underexpanded jet originally by …

    Hotovec-Ellis, Alicia Jean2014

    … similar waveforms when recorded at a seismic instrument. Repeating earthquakes have been observed in a wide variety of environments: from fault systems (such as the San Andreas and Cascadia subduction zone), to hydrothermal areas and volcanoes. Volcano seismologists are particularly concerned …

  9. Documenting the Earthquake History of the Thousand Springs Fault in Summer Lake Basin, Oregon, USA

    Curtiss, Elizabeth2020

    <p>Defining seismic hazards in low-strain-rate regions such as the northwestern Basin and Range can be difficult due to the infrequency of earthquakes. Revealing the earthquake records of low-strain-rate regions can refine our understanding of the variability of earthquake sizes and recurrence …
