margin: insights from sequence-stratigraphic analysis. J. Geophys. Res. 115, B12102, p. 1-13.
(Seismic profiles over Pleistocene shelf margin of Malacca Strait-Mergui Basin NE of N Sumatra show three
sediment packages interpreted as submarine landslides, aged 20-30 ka, 342-364 ka and 435-480 ka. Events
occurred near times of sea-level lowstands, implying that high sediment influx during glacial periods is
essential for basin-margin submarine landsliding)
