Figure 1

Distribution of DONET stations and submarine topography. The map in the inset shows the location of close-up region, and the blue line shows the track of Typhoon Man-yi from 13 to 17 September, 2013. The color contour is consistent with the marine depth. The black circles show the stations. The A, B, D, and E nodes are located at a depth of approximately 2,000 m, whereas the C node is located approximately 4,000 m deep. The square indicates the midpoint of the array of all the stations of the A, B, D, and E nodes. The wave front of a very long-period IG wave hypothetically emanating from the midpoint of the array is shown for every 15 min of travel time. The two gray and black lines show the azimuthal windows of 110° to 130° (ESE) and 140° to 160° (SSE), respectively.
