摘要 Using the Hill estimator, general multifractal characteristics of events in the New Zealand area have been dis-cussed. Results show that the spatial distribution of shallow events has apparent clustering characteristics, inde-pendent of the threshold magnitude; but for deep events these characteristics are not clear. While the time interval distribution has obvious clustering characteristics both for deep and shallow events, although with a different scal-ing range, the Hill estimates tend to indicate that the time interval distribution has a unifractal rather than a multifractal nature. All above reveal that the seismicity nature for shallow and deep events is apparently different.
