| Zusammenfassung |
| We examine the event statistics obtained from two differing simplified models
for earthquake faults. The first model is a reproduction of the Block-Slider
model of Carlson et al. (1991), a model often employed in seismicity
studies. The second model is an elastodynamic fault model based upon the
Lattice Solid Model (LSM) of Mora and Place (1994). We performed simulations in
which the fault length was varied in each model and generated synthetic
catalogs of event sizes and times. From these catalogs, we constructed
interval event size distributions and inter-event time distributions. The
larger, localised events in the Block-Slider model displayed the same scaling
behaviour as events in the LSM however the distribution of inter-event times
was markedly different. The analysis of both event size and inter-event time
statistics is an effective method for comparative studies of differing
simplified models for earthquake faults. |
