From: Large-scale mass wasting in the western Indian Ocean constrains onset of East African rifting
Seismic Line 1, oriented W-E and intersecting seismic Line 3 (red arrow), is perpendicular to the slope of the western Indian Ocean offshore the Rufiji River delta (location in Fig. 1). Insets a–d highlight the morphological and seismic expression variability of the Mafia mega-slide and bounding units. M1–M4 are the main seismic horizons identified in this study and tied to the two wells (see Fig. 2 for the ages). The Mafia mega-slide is highlighted in green. MTD: mass-transport deposit. Noninterpreted version of Line 1 is available in the Supplementary Fig. 2.
