Map and examples of observed seismogram envelopes around the Nankai Trough. The colored circles in a represent local earthquakes used in this study, and the triangles and diamonds are locations of F-net and DONET stations, respectively (Aoi et al. 2020). Filled triangles and diamonds are stations used in b. The solid and dotted lines in b are horizontal and vertical envelopes. The envelopes at DONET and F-net stations are represented by blue and black lines, respectively. c Smax and coda amplitudes as a function of epicentral distance. The filled blue and open diamonds are horizontal and vertical amplitudes at DONET stations, respectively. The filled and open triangles are those at F-net stations
