Simulation results for a sequence of five earthquakes a without periodic boundaries, b \(\lambda = 2L\), and c \(\lambda = 10L\), where \(L = 2~{\text{km}}\). Blue and red lines indicate distribution of slip every \(10^{7}\) s and \(10^{{ - 2}}\) s during earthquakes, respectively. The case in a was calculated using the proposed method, and those in b and c were calculated by the method of Noda and Lapusta (2010)
