The recently collected EM-300 data revealed these two back-to-back calderas. The calderas were initially discovered in 2003 by K. Hoernle,(PI, IFM- Geomar, Kiel), R. Werner (Chief Scientist, IFM- Geomar, Kiel), D. Christie (OSU) and colleagues (Christie et. al, 2005). Although the calderas had been previously discovered, they were never named.
