• Description:
  Deep subaqueous volcanic eruptions (>500 m below sea level (mbsl)) remain enigmatic due to a lack of visual observations and difficulty recreating ambient conditions in the lab. Eruptive activity at West Mata seamount in May 2009 remains one of two deep subaqueous eruptions to have ever been filmed. A distinct low-intensity eruptive style, termed bubble escape activity, was observed at Hades vent (1200 mbsl) characterized by the ascent and implosion of 0.2 - 1 m diameter volatile-filled vapor bubbles (Resing et al., 2011). Video of this volcanic activity is used to constrain simple numerical models and produce the first subaqueous eruption actualistic model driven by visual observations.
