In the original article, there was a mistake in the legend for S-net buried and S-net non-buried stations in Figures 4, 5, and 6. The symbols for the S-net buried and S-net non-buried stations were mistaken for each other. The correct legend appears below.
The authors apologize for this error and state that this does not change the scientific conclusions of the article in any way. The original article has been updated.
FIGURE 4
FIGURE 4. Plots of PGAs (A, B, C) and PGVs (D, E, F) as a function of hypocentral distance for the 2018 event (see Table 1 for the event information). The left and middle panels show the peak values of the 20 s time windows starting from the S-onset for the horizontal (hor) and vertical (ver) components, respectively. The right panels show the peak values of the 5 s time windows starting from the P-onset for the vertical components. The plotted values for the horizontal components are the larger ones of the peak values of the two horizontal components. The circles denote the K-NET/KiK-net stations, simply written as Land in the legends, and the triangles S-net stations of which the inverse triangles (blue colored) denote the buried S-net stations. The black and red solid lines represent the fitted lines between the observed values and hypocentral distances for the K-NET/KiK-net and S-net stations in each panel. The solid and dashed grey lines denote the median prediction curves and range of one standard deviation for soil site condition in (A) and Vs30 = 300 m/s in (D) using the GMPEs in Si and Midorikawa (1999), written as SM (1999) in the legend, for an intraslab-type earthquake. The dashed black and red lines in (B, C) and (E, F) denote the fitted black and red solid lines in (A) and (C), respectively, for comparison.
FIGURE 5
FIGURE 5. Same as Figure 4, but for the 2020a interplate event (see Table 1 of the original article for the event information). The GMPEs for an interplate-type earthquake are used in the panels (A) and (D).
FIGURE 6
FIGURE 6. Same as Figure 4, but for the 2020b crustal event (see Table 1 of the original article for the event information). The GMPEs for a crustal-type earthquake are used in the panels (A) and (D).
