摘要
///327 M≥5.0 earthquakes with relatively integrated data are investigated. The whole seismic area in Chinese mainland is divided into 5 study regions. The authors spatially scanned the data in each region for seismic belt pattern with a uniform criterion. It is found that the belt pattern exists before 96 moderate-strong earthquakes, being 29% of the total earthquakes. The result indicates that no significant correlation exists between the mainshock magnitude M and the belt duration time t, and the belt length L, when the belt earthquake magnitude M<5.5. When M≥5.5, a linear relation would exist, but with poor data correlation.
