The ${\kappa }_1$ values as well as the values of the change $\Delta {\mathsf{\Lambda }}_{2000}$, $\Delta {\mathsf{\Lambda }}_{3000}$ and $\Delta {\mathsf{\Lambda }}_{4000}$ of the complexity measures versus the conventional time since 00:00 LT on 9 March 2011 until the M9 Tohoku earthquake occurrence. The shaded area marks the period in the morning of 10 March 2011 during which the condition ${\kappa }_1=0.070$ is fulfilled.
