| Zusammenfassung |
| We study main parameters of earthquakes from the perspective of the
first digit phenomenon: the nonuniform probability of the lower
first digit different from zero compared to the higher ones. We
found that source parameters like coseismic slip distributions at
the fault and coseismic inland displacements show first digit
anomaly. We also found the tsunami runups measured after the
earthquake to display the phenomenon. Other parameters found to obey
first digit anomaly are related to the aftershocks: we show that
seismic moment liberation and seismic waiting times also display an
anomaly. We explain this finding by invoking a self-organized
criticality frame. We show that critically organized automata show
the first digit signature and we interpret this as a possible
explanation of the behavior of the studied parameters of the Tohoku
earthquake. |
