Why Volcanoes Fall Down
V11C-2791: Combining slope stability and groundwater flow models to assess stratovolcano collapse hazard
Shaul Hurwitz, 8:00 - 12:20, Moscone South-Poster Hall
Flank collapses are a well-documented hazard at volcanoes. Collapse volumes depend on a complex interplay
of mechanical factors and layering – it isn’t just one thing that causes volcanoes to fall down.
Ocean Island Volcanoes—Not Always the Same
V12A-01: Ocean island volcanoes—Just how similar are they?
Michael Poland, 10:20 - 10:35, Moscone South - 310
Similarities in ocean island volcano shape and eruptive activity create a perception that these volcanoes are all
the same: differences from Kīlauea, Galápagos, and La Réunion volcanoes.

Tracking Tree Kill to Assess Changes in Magma CO2 at Horseshoe Lake
EP21D-0905: Classifying historic images to quantify spatial and temporal changes in tree mortality at Horseshoe Lake
(Mammoth Mountain, California)
Madeleine O'Brien, 08:00 - 12:20, Moscone South - Poster Hall
Since 1990, large areas of tree kill surrounding Horseshoe Lake, SE of Mammoth Mountain has been attributed
to the release of magmatic carbon dioxide into the soil via rock fractures, stimulated by the emplacement of a
basaltic dike beneath Mammoth and an accompanying earthquake swarm in 1989.
Helicopter Survey Finds Areas Susceptible to Landslide at Mount Baker
NS21C-08: Identifying alteration and water on Mt. Baker, WA with geophysics: Volcanic landslide hazards
Carol Finn, 09:45 - 10:00, Moscone West - 3024
Hydrothermally altered rocks can weaken volcanic edifices, increasing the potential for catastrophic collapses.
At Mt. Baker, collapses have generated numerous debris flows and constitute the greatest volcanic hazard.

How Much Does a Volcano Contribute to the Global Gas Budget?
V31E-01: Quantifying CO2 degassing from volcanoes – Recent major advancements and future challenges (Invited)
Cynthia A Werner, 08:00 - 08:15, Moscone South - 308
Degassing from active volcanoes, like Masaya, Turrialba, Poas, Villarica, Nevado del Ruiz, is a major focus of
the Deep Carbon Observatory’s DECADE initiative.
What Did We Learn at Pinatubo?
V32A-01: Key lessons and new directions from Pinatubo 1991 (Invited)
John S Pallister, 10:20 - 10:35, Moscone South - 104
The 1991 eruption of Mt. Pinatubo, Philippines, taught scientists about seismicity, magma mixing, and
precursory phenomena. The violence of the eruption continues to guide scientific discussion about forecasting
eruptions, volcano hazards, and preparing for the next one.

What is Possible? Global Dataset Helps Improve Eruption Forecasting
NH44A-01: Monitoring and modeling: The future of volcanic eruption forecasting (Invited)
Michael P Poland, 16:00 - 16:15, Moscone South - 103
Scientists are developing robust datasets from volcanic behavior around the world. More observations and
better understanding of the underlying physics of unrest will improve forecasts of such activity.
Magma Reservoirs: How Well Do We Really Know Them?
V44A-02: Magma reservoirs: How well do we know them, why does it matter, and how can we do better? (Invited)
Jacob B Lowenstern, 16:15 - 16:30, Moscone South - 308
Yellowstone presents compelling evidence for a large crustal magma body; yet geophysical studies do not
directly support these observations. Could there be significant undetected molten regions, or can crystal mush
transition rapidly to eruptible magma on short timescales?
Where Does Long Valley Magma Come From?
V44A-04: Development of a three-dimensional geologic model of the Long Valley volcanic system, California, using
magnetotellurics
Jared Peacock, 16:45 - 17:00, Moscone South - 308
The Long Valley volcanic system in Eastern California is an active and dynamic magmatic system.
Magnetotelluric data was used to produce a 3-D geologic model of the system.

Global Database to Answer Common Questions That Arise During Volcanic Crises
NH53B-2002: The eruption forecasting information system: Volcanic eruption forecasting using databases
Sarah E Ogburn, 13:40 - 18:00, Moscone South - Poster Hall
The Eruption Forecasting Information System (EFIS) project is a new initiative of the U.S. Geological SurveyUSAID Office of Foreign Disaster Assistance (OFDA) Volcano Disaster Assistance Program.
What’s the “Swarmiest” Volcano of the Cascade Range?
V53C-3106: Seismicity of cascade volcanoes: Characterization and comparison
Weston A Thelen, 13:40 - 18:00, Moscone South - Poster Hall
Five Cascade volcanoes are consistently seismogenic (Mount Rainier, Mount St. Helens, Mount Hood,
Newberry Caldera, Lassen Volcanic Center). Others (South Sister, Mt. Baker, Glacier Peak, Crater Lake and
Mount Shasta) have lower rates of seismicity.
Vog and Volcanic Gas Hazards in Hawaii
V53A-3074: Kilauea’s double eruption, 2008-2016: volatile budget and associated hazards
Jeff Sutton, 13:40 - 18:00, Moscone South - Poster Hall
Changes in gas emissions and magma supply shed light on long-term elevated gas emissions that present
ongoing human health concerns and agricultural disasters.
