  • Age systematics of two young en echelon Samoan volcanic trails 
    Koppers, Anthony A. P.; Russell, Jamie A.; Roberts, Jed; Jackson, Matthew G.; Konter, Jasper G.; Wright, Dawn J.; Staudigel, Hubert; Hart, Stanley R. (American Geophysical Union, 2011-07-29)
    The volcanic origin of the Samoan archipelago can be explained by one of three models, specifically, by a hot spot forming over a mantle plume, by lithospheric extension resulting from complex subduction tectonics in the ...
  • A fluorescein tracer release experiment in the hydrothermally active crater of Vailulu'u volcano, Samoa 
    Hart, Stanley R.; Staudigel, H.; Koppers, Anthony A. P.; Girard, A. P. (American Geophysical Union, 2003-08-14)
    On 3 April 2001, a 20 kg point source of fluorescein dye was released 30 m above the bottom of the active summit caldera of Vailulu’u submarine volcano, Samoa. Vailulu’u crater is 2000 m wide and at water depths of 600 ...
  • Hydrothermal venting at Vailulu'u Seamount: The smoking end of the Samoan chain 
    Staudigel, H.; Hart, Stanley R.; Koppers, Anthony A. P.; Constable, C.; Workman, R.; Kurz, M.; Baker, E. T. (American Geophysical Union, 2004-02-10)
    The summit crater of Vailulu’u Seamount, the youngest volcano in the Samoan chain, hosts an active hydrothermal system with profound impact on the ocean water column inside and around its crater (2 km wide and 407 m de ...
  • Vailulu'u Seamount 
    Koppers, Anthony A. P.; Staudigel, Hubert; Hart, Stanley R.; Young, Craig; Konter, Jasper G. (The Oceanography Society, 2010-03)
    Vailulu’u seamount is an active underwater volcano that marks the end of the Samoan hotspot trail (Hart et al., 2000). Vailulu’u has a simple conical morphology (Figure 1) with a largely enclosed volcanic crater at ...
  • Vailulu'u undersea volcano: The New Samoa 
    Hart, Stanley R.; Staudigel, H.; Koppers, Anthony A. P.; Blusztajn, J.; Baker, E. T.; Workman, R.; Jackson, M.; Hauri, E.; Kurz, M.; Sims, K.; Fornari, D.; Saal, A.; Lyons, S. (American Geophysical Union, 2000-12-08)
    Vailulu'u Seamount is identified as an active volcano marking the current location of the Samoan hotspot. This seamount is located 45 km east of Ta'u Island, Samoa, at 169°03.5′W, 14°12.9′S. Vailulu'u defines the eastern ...
  • Vailulu’u Seamount, Samoa: Life and death on an active submarine volcano 
    Staudigel, Hubert; Hart, Stanley R.; Pile, Adele; Bailey, Bradley E.; Baker, Edward T.; Brooke, Sandra; Connelly, Douglas P.; Haucke, Lisa; German, Christopher R.; Hudson, Ian; Daniel Jones; Koppers, Anthony A. P.; Konter, Jasper; Lee, Ray; Pietsch, Theodore W.; Tebo, Bradley M.; Templeton, Alexis S.; Zierenberg, Robert; Young, Craig M. (The National Academy of Sciences of the USA, 2006-04-25)
    Submersible exploration of the Samoan hotspot revealed a new, 300-m-tall, volcanic cone, named Nafanua, in the summit crater of Vailulu’u seamount. Nafanua grew from the 1,000-m-deep crater floor in <4 years and could ...
