Malumalu
About Malumalu
The Malumalu seamount (also called Southeast Bank) is about 50 km SW of Ta'u Island and 90 km SSE of Tutuila in the Samoan Islands. The edifice, at the end of the Mula volcanic ridge that extends back to Tutuila, has basal diameter of about 25 km. Radiometric measurements were done by Sims et al. (2008), who reported that 230Th/238U, 231Pa/235U, and 226Ra/230Th data indicated at least three flows with maximum eruption ages in the last 350,000 years; one flow with excess 231Pa was inferred to be less than 150 ka, and another with excess 226Ra was inferred to be less than 8 ka.
