A team of scientists from Oregon State University and NOAA found evidence that the submarine volcano, whose top is about 300 m below sea level, is currently erupting (or at least has been very recently).
The expedition "Submarine Ring of Fire 2014 - Ironman" found this evidence in form of two observations: very strong plumes coming from the top of the seamount were detected that show characteristics that can only be explained by an eruption. During a previous survey in 2006, only hydrothermal activity, including the spectacular discovery of a liquid sulfur pond, were seen at the volcano.
Second, a comparison of bathymetric data shows that new craters have formed, something which also is difficult to explain other than by an eruption.
