| Zusammenfassung |
| We estimate the loading rate
in southern California and the change in stress induced by a
transient slip event across the San Andreas fault (SAF)
system in central California,
using a model of static fatigue.
We analyze temporal properties of aftershocks
in order to determine the time delay
before the onset of the power law aftershock decay rate.
In creep-slip and stick-slip zones, we show that the rate
of change of this delay is related to seismic and aseismic
deformation across the SAF system.
Furthermore, we show that this rate of change is
proportional to the deficit of slip rate along the SAF.
This new relationship between geodetic and seismological data is in
good agreement with predictions from a Limited Power Law model
in which the evolution of the duration of a linear aftershock
decay rate over short time results from variations
in the load of the brittle upper crust. |
