The grid search method to obtain the best solution for the focal aftershock mechanism on June 8 as a function of time sampling and variance for each model speed and bandpass filter range as shown in Table 2. The blue, yellow, red, brown, and green color beachballs indicate the filtering used by Pinar, Kasemsak, Miyatake, and this study, respectively. The velocity models used include a AK135, b CRUST, c PREM, d JB and e Koulakov
