| Zusammenfassung |
| We explore bursty multiscale energy dissipation from earthquakes
flanked by latitudes 29 and 35.5° S, and longitudes 69.501
and 73.944° W (in the Chilean central zone). Our work
compares the predictions of a theory of nonequilibrium phase
transitions with nonstandard statistical signatures of earthquake
complex scaling behaviors. For temporal scales less than than 84 h,
time development of earthquake radiated energy activity follows an
algebraic arrangement consistent with estimates from the theory of
nonequilibrium phase transitions. There are no characteristic scales
for probability distributions of sizes and lifetimes of the activity
bursts in the scaling region. The power-law exponents describing the
probability distributions suggest that the main energy dissipation
takes place due to largest bursts of activity, such as major
earthquakes, as opposed to smaller activations which contribute less
significantly though they have greater relative occurrence. The
results obtained provide statistical evidence that earthquake energy
dissipation mechanisms are essentially "scale-free," displaying
statistical and dynamical self-similarity. Our results provide some
evidence that earthquake radiated energy and directed percolation
belong to a similar universality class. |
