Santa María del Oro before and after: Single-beam acoustic measurements of water depth made in 2000¹⁸ (A) and a composite of data obtained between 2009 and 2016 (B) have been interpolated to produce these surfaces. Despite the coarse spatial resolution of our data (see Supplementary Fig. 1), differences between surveys and scars near 30 m depth in Panel (B) suggest the occurrence of underwater landslides in Agua Caliente Bay (red, dashed rectangle in Fig. 1A).
