January 22, 2013 - "Volcano Awareness Month: A Below-the-Scenes Look at Kīlauea Volcano's Plumbing System"
The magma storage and transport system beneath a volcano can be envisioned like the plumbing system of a house. Magma "pipes" connect different reservoirs, and can feed magma toward the surface or transport it laterally beneath the surface. Thanks to over a century of research, volcanologists have a good idea of where magma is stored beneath Kīlauea and how magma moves between summit storage areas and eruption sites (which can be many miles away) along the volcano's rift zones. USGS Hawaiian Volcano Observatory scientist Michael Poland will present a picture of what Kīlauea's subsurface might look like based on observations from eruptions, earthquake patterns, ground deformation, chemical changes, and geologic studies
