    • Abstract
  • Any pair of m1gz,m1gh,mmxz, and mmxh in the six eastern provinces of China show good linear relation with each other this makes it easy to convert from one to another scale. mmxh may replace ML(ECH) as the local earthquake magnitude scale for the six eastern provinces yet preserving the level of ML(ECH). The scale mmxh is 0.36 magnitude units higher than ML(SC) for southern California. By comparing Rmax(△) with R3(△) of Yunnan, it is found that y value of MAX phase about 1 second in Yunnan region is half as large as that in the six eastern provinces of China.Observations indicate that mmmxhmb between magnitude 4-5. It follows therefore that mb (east China)mb (west U. S.). This is supported by the result that the attenuation coefficient y in eastern China is approximately the same as that in western United States.
