Distribution of the standard deviation (1σ) of the estimated slip (Fig. 12) in the N170E direction (left panel) and N80E direction (right panel) at each subfault. Map region corresponds to Area A in Fig. 1. a, b Standard deviation of the estimated slip for the first period (29 December 2015–1 January 2016). c, d Standard deviation of the estimated slip for the second period (1 January to 1200 on 5 January). e, f Standard deviation of the estimated slip for the third period (1200 on 5 January–7 January)
