“…However large sandpiles (on the order of 100 grain diameter) no longer showed the finitesize scaling but rather generated periodic large avalanches. Similar results were obtained by Rosendahl et al (1993) who carried out a sandpile experiment with the apparatus and techniques similar to those of Held et al (1990). Rosendahl et al (1994) discussed the possibility of prediction of a major large avalanche based on the change in the rate of small avalanche activity prior to it.…”

We have performed an experiment in which a conical sandpile was built by slowly dropping sand onto a circular disk through a funnel with a small outlet. Avalanches (sand dropping off the disk) occurred, the size and the number of which were observed. It was seen that the behavior of avalanches (frequency-size distribution) was determined solely by the ratio of grain size to disk size, which is consistent with earlier studies. We categorize the behavior into three types: (1) the self-organized criticality (SOC) type (obeying Gutenberg-Richter's law), (2) the characteristic earthquake (CE) type where only large avalanches are almost periodically generated, and (3) the transition type. The transition from SOC to CE type drastically occurs when the ratio of grain diameter to disk radius is reduced to about 0.02. The underlying mechanism to cause the transition is considered. Results of simulation by cellular automaton models, an experimental result showing that a conical pile has a stress dip near its center, and a two-dimensional simulation building up a conical pile, all suggest that the transition occurs due to a change in stress profile inside and near the surface of the pile. Although we are unfortunately not able to understand the detailed mechanism at the present stage, it seems very important to further investigate the underlying physics of the transition because it presumably provides us a clue to understand the mechanism of the periodicity of large characteristic earthquakes and may open a way for earthquake prediction.

“…Our experimental method is basically similar to that of Held et al (1990) and Rosendahl et al (1993). In this paper, we present the result of the experiment and consider its implication for SOC and characteristic earthquake.…”

“…Bak et al (1987Bak et al ( , 1988 postulate that the cascading collapse behaviour observed in their model is similar to what happens when grains of sand are added to natural sand piles, where the addition of a single grain could cause an avalanche whose size could vary from a single grain to that of the whole length of the slope (e.g. Jaeger et al, 1989;Held et al, 1990;Rosendahl et al, 1993). Bak et al (1987) referred to this tendency to evolve towards a dynamic equilibrium around a critical state as self-organized criticality (SOC).…”
