1) Seismicity rate and model stress both increase or both decrease.
2) Seismicity rate and model stress change in opposite directions.
3) Based on test.
4) Based on binomial test.
5) Control stress model in which stress change is Dt(1/(d+1)), where d is distance (km) from the Nojima - Rokko fault trace, and Dt is the static shear stress drop on the fault.
