The coda recorded of the WIGWAM reverberations at Point (Pt.) Sur, California, and Kaneohe, Hawaii, span about a 3.8 hr duration. The length of this record makes it difficult to make a detailed comparison between the measured and computed coda. Figure S1a–i shows a sequence of figures comparing these coda for the recordings at Pt. Sur, California. The reader can pan through the figures by clicking on the arrows.
As originally determined by Sheehy and Halley (1957), the peaks of the coda obtained at Pt. Sur and Kaneohe can usually be identified as caused by reflections from particular topographic features located throughout the North or South Pacific Oceans. Figure S2a–am and Figure S3a–x show sequences of figures that show the geodesic paths associated with time increments of the recorded coda. The reader can pan through these figures by clicking on the arrows. Most often, the features of the recorded coda are a result of simultaneous arrivals of rays from disparate locations.

Figure S2a (aa, ab, ac, ad, ae, af, ag, ah, ai, aj, ak, al, and am), b, c, d, e, f, g, h, i, j, k, l, m, n, o, p, q, r, s, t, u, v, w, x, y, and z. The features of the recorded coda at Pt. Sur, California were identified as originating from reflections from topographic features located throughout the North and South Pacific basins. Often a feature or peak of the coda actually originates from multiple geodesic paths arriving simultaneously from disparate locations. The reader can pan through the figures showing ray paths associated with features of the entire coda by clicking on the arrows.
Figure S3a, b, c, d, e, f, g, h, i, j, k, l, m, n, o, p, q, r, s, t, u, v, w, and x. Same as for Figure S2a–m, but for the coda recorded at Kaneohe, Hawaii.
