甲有关地震震级存在的问题就目前为止,震级的重要性是不容忽视的,地震学中许多重要现象都与震级M找到了关系。如: I_0=1.5M-1.5 logl=0.55M-2.0 logld≈2M-10
A Problem with Earthquake Magnitudes So far, the importance of magnitude can not be ignored, and many of the important phenomena in seismology have been related to the magnitude M. Such as: I_0 = 1.5M-1.5 logl = 0.55M-2.0 logld ≈ 2M-10
