| Zusammenfassung |
| The method for detection of clusters on the basis of event
space–time dependence is classically applied for foreshock–mainshock–aftershock sequences for which event
connectedness is generally accepted. In the paper, this
approach is used to investigate the whole event catalogue
of foreshock and aftershock sequences filtered from the
events with small magnitudes, in which connected events are
also determined. The space scale is extended due to the
inclusion of the parameter of seismic event connectedness
in the direction of dislocation shift that allows us to
consider the obtained connected events as clusters in a
shear flow. A statistical model of the shear flow was
constructed by catalogue decomposition into timescales and space
scales defined analytically. A modelling algorithm of the
shear flow was developed and its stability to initial
condition change was investigated. Shear flow structure and
arising non-local deformation characteristics which may be
the criteria for dynamic process activity in the considered
subduction zone of the Kuril–Kamchatka island arc were
analysed. |
