From: Characteristics of seismic activity before and after the 2018 M6.7 Hokkaido Eastern Iburi earthquake
Non-stationary ETAS estimate right before the M6.7 main shock (iii, 6-Sep-2018). The red and blue curve indicates the background rate μ(t) and triggering coefficient K0(t) for the period before and after the M5.1 event (ii, 1-Jul-2017), respectively, with 2-sigma error bounds in dashed curves. The spiky gray curve shows the intensity rate λ(t) against time. The + signs in the bottom show the magnitudes.
