| Zusammenfassung |
| One of the most widespread spring-block earthquake models, the
Olami-Feder-Christensen model, is investigated without making the
assumption that the duration of individual earthquakes is negligible.
While the Gutenberg-Richter law for the size distribution
of earthquakes is preserved qualitatively for earthquakes of finite
duration, the b-value decreases with increasing earthquake duration.
The effect decreases with increasing lattice size, although it is
not clear whether it completely vanishes in the limit of infinite grid size.
For realistic values of earthquake duration, the effect is
negligible, so that the original model with zero earthquake duration
is appropriate for most applications. |
