Table 1 The 1D velocity structure used in this study, following Saiga et al. (2010).
From: Repeating deep tremors on the plate interface beneath Kyushu, southwest Japan

0–5 | 3.2 | 5.5 |
5–10 | 3.4 | 5.8 |
10–20 | 3.7 | 6.3 |
20–30 | 4.1 | 6.9 |
30–35 | 4.3 | 7.6 |
35–50 | 4.5 | 7.9 |
50–75 | 4.6 | 7.9 |
