Geology The Samoan Islands are composed of linear chains of volcanic islands near the boundary between the Tonga plate and the Pacific plate. The Pacific plate slightly moves west-northwest at a slow speed, creating submarine volcanoes. The youngest and most active volcano is named Vailuluʻu, with a volcanic cone just about 300 m yd off the crater of Vailuluʻu. Other than volcanoes, there are multiple volcanic islands situated west of Vailuluʻu.US Department of Commerce National Oceanic and Atmospheric Administration 2017 American Samoa Expedition: Suesuega o le Moana o Amerika Samoa: Background: Volcanic Islands and Seamounts in the Samoan Region: NOAA Office of Ocean Exploration and Research https://oceanexplorer.noaa.gov/okeanos/explorations/ex1702/background/geology/welcome.html 2024-10-05 oceanexplorer.noaa.gov The islands' geology consists of mafic material, like basalt and gabbro, because of the Samoa hotspot.Kear David 1967-12-01 Geological notes on Western Samoa http://dx.doi.org/10.1080/00288306.1967.10423228 New Zealand Journal of Geology and Geophysics 10 6 1446–1451 10.1080/00288306.1967.10423228 1967NZJGG..10.1446K 0028-8306 subscription Earthquake The earthquake measured w y8.0 and struck at a depth of 15 km mi off.
