In 2012, the USGS Hawaiian Volcano Observatory (HVO) marked its 100th anniversary with a number of special events, one of which was "Hawaiian Volcanoes: From Source to Surface," a Chapman Conference convened by the American Geophysical Union in August.
Scientists from around the world—including many from HVO and the University of Hawaiʻi—gathered on Hawaiʻi Island to review past, present, and future research on how Hawaiian volcanoes work, with focus on magma origin, ascent, and storage; eruptions; volcano monitoring; and questions still to be answered about Hawaiian volcanism.
These topics were addressed through 20 keynote presentations,
13 short talks, numerous poster presentations, and 4 field trips. Slides and audio files of the conference presentations are posted on
UH-Hilo's Hawaiian Volcanoes: From Source to Surface website.
Keynote presentations and short talks provided by current and former HVO scientists included:
- HVO: It's first 100 years of advancing volcanology
- Growth of the Island of Hawaiʻi: Deep-water perspectives
- Effusive and explosive cycles at Kīlauea: What do they mean?
- A 200-year look at Hawaiian volcanism—the last and the next 100 years
- Eruptive processes revealed by variations in Kīlauea gas release
- Does activity at Kīlauea influence eruptions at Mauna Loa?
- Ultra-energetic, jet-like eruption at Kīlauea: The Kulanaokuaiki-3 tephra
Posters presented by HVO scientists during the conference included:
- Degassing highlights during the 2011-2012 eruptive activity at Kīlauea Volcano, Hawaiʻi
- Kīlauea's magma plumbing system
- Petrologic evidence for a large, actively convecting summit magma chamber within Kīlauea Volcano
- A background of seismic anisotropy at Kīlauea Volcano and changes associated with the summit eruptive vent
