Zusammenfassung |
Fractal and occasionally multifractal behaviour has been
invoked to characterize (independently of their magnitude) the spatial distribution of
seismic epicenters, whereas more recently, the frequency distribution of magnitudes
(irrespective of their spatial location) has been considered as a manifestation of
Self-Organized Criticality (SOC). In this paper we relate these two aspects on rather
general grounds, (i.e. in a model independent way), and further show that this involves a
non-classical SOC. We consider the multifractal characteristics of the projection of the
space-time seismic process onto the horizontal plane whose values are defined by the
measured ground displacements, we show that it satisfies the requirements for a first
order multifractal phase transition and by implication for a non-classical SOC. We
emphasize the important consequences of the stochastic alternative to the classical
(deterministic) SOC. |
