Using the method described in (Xu et al., 1994, 1997) the spatial ordering of 28 large shallow earthquakes (M >-= 7.5) occurred in Japan since 1890 is studied. The distances between each pair of these earthquake epicenters show a significant peak in the range of 400-599 km. Most of earthquakes are characterized by equidistant ordering. Each earthquake can be related to many other earthquakes with different equidistant orderings. A total of 22 ordered series are found, and they are classified into six type of orderings. The relationships among 28 shallow earthquakes seem to indicate that they are the phenomena of a multi-level network-like system.
