  earthquake size
The earthquake size distribution is generally considered to obey the Gutenberg-Richter (GR) law.
      
The initial subevent of the 1994 Northridge, California, earthquake: Is earthquake size predictable
      
Final earthquake size may be predictable from an ISE's seismic signature in the preslip model but not in the cascade model.
      
In this model, the duration of the ISE signal scales with the ultimate size of the earthquake, suggesting that nucleation and earthquake size are determined by a more predictable, measurable, and organized process.
      
To this catalogue, for a most rational and best-justified hazard analysis, we add estimates of earthquake size translated from active faulting characteristics.

By applying the spectral theory of seismic sources of dislocation models and the observed data, the maximum particle displacement or velocity of the far-field body-wave (the earthquake magnitude) is shown to depend on two independent source dynamic parameters seismic moment M0 and the characteristic frequency of body-wave spectra f0. Consequently, it is impossible to characterize the intensity of an earthquake with the seismic moment or to represent the size of an earthquake with the fault-size (the characteristic...

By applying the spectral theory of seismic sources of dislocation models and the observed data, the maximum particle displacement or velocity of the far-field body-wave (the earthquake magnitude) is shown to depend on two independent source dynamic parameters seismic moment M0 and the characteristic frequency of body-wave spectra f0. Consequently, it is impossible to characterize the intensity of an earthquake with the seismic moment or to represent the size of an earthquake with the fault-size (the characteristic frequency of body-wave spectra), provided the other source parameter is not kept constant. The characteristic frequency of body-wave spectra carries the information of the duration of source body-wave pulse. The physical significance of the earthquake magnitudes is discussed from this point of view.

本文应用位错模型地震震源波谱理论和观测资料,论证了远场体波质点位移或速度最大值(地震震级)决定于彼此独立的两个震源动力学参数地震矩M_0和体波波谱特征频率f_0。因此,仅以地震矩表征地震强度或仅以断层尺度(体波波谱特征频率)分类地震大小,只在另一个震源参数保持为常数时才有可能。体波波谱特征频率携带着震源体波脉冲持续时间的信息。据此,探讨了地震震级的物理含义。

The first paper briefs research of earthquake magnitude problems in the following 3 aspects:firstly, the five relatively conventional magnitude scales are given,namely near earthquake magnitude scale,surface- wave magnitude scale,body-wave magnitude scale,moment magnitude scale and duration magnitude scale. Secondly,the existing problems in magnitude scales are mentioned,such as deviations among magnitude determinations and their possible causes;the physical meaning of magnitude held by different authors are different,resulting in the present chaos among various magnitude scales.Thirdly,the two approaches for improving magnitude scales are described,such as further improvement of the Gutenberg-Richter magnitude scale system and adopting a uniform magnitude scale;the establishment of a new magnitude scale like the moment magnitude scale or the mono-chromatic magnitude scale system;the concept of latter suggested by Prof.Duda is then briefed.

震级是地震大小的尺度,是地震的一个主要参数,也是地震学里研究得最多的一个参数。目前世界上所用的震级很不统一,测定的偏差也大,这对地震的研究带了很多麻烦。随着地震学的发展,震级问题的矛盾越来越突出。近十几年来,它已成为国际地震学家注意的一个重要问题,专门成立震级委员会来研究它。近年来,我国地震学界对震级问题的研究也很重视,已将它列为重点科研项目之一,组织力量进行研究。本文简介三个问题,一是较为常用的震级标度;二是震级标度存在的问题;三是改进震级标度的途径。

Homogeneous magnitude system of the mainland China has been made from the data of SK instrumental network, using the method that together obtain earthquake magnitude, calibration function and correction of the site condition. Four new calibration functions have been obtained for P-wave PZ, PⅡ, and S-wave SH, SV from the distance of 2.5° to 100° degree. 21 corrections of the site condition are also obtained. The standard error of single station measurement of earthquake magnitude is about 0.21-0.23, utilizing the new calibration function and the corrections of site condition. The earthquake the magnitude of which is equal to or greater than 6.0 can be usually recorded by 16 stations. In this case, the standard error of average magnitude over the network is about 0.05. The body wave magnitude mSK, from SK instrumental measurement has a systematic difference to mb and mB, because mSK, mb and mB depend on instrument of measurement strongly. The principle of making mSK close to Ms is adopted.We have a suggestion of magnitude of displacement spectrum: the earthquake will be equal to each other at one frequency when their average displacement spectrum over on some focal reference sphere has the same value for P-wave (or S-wave). This magnitude scale has following advantage: 1. The magnitude of network on different region of all over world can be unified in view of it being absolute mechanical scale. 2. It has obvious meaning in physics. It can represent the size of earthquake and can be defined for any size and slow earthquakes as well as has no saturation trouble. 3. It can link up the current magnitude scale. 4. The measurement is easy and has less error for the displacement instrumental record.

用 SK 地震仪台网的资料,用联合确定地震震级、量规函数和台基校正值的方法,做出了中国大陆地区的均一震级系统,得到了 PZ、PH、SH、SV 四个震相从2.5°—100°新的量规函数,以及我国21个基准台的台基校正值.用这四个量规函数加上台基校正,求得的单台震级的标准误差为0.21—0.23级.6级左右的地震一般都有16个以上台记录到,这时求得的台网平均震级的误差可在0.05级左右.由于体波震级强烈地依赖于仪器类型,所以,我们求得的体波震级 m_(sk)与 m_b 或 m_B 有系统差.我们采取了使 m_(sk)与 M_s 接近的原则.提出了位移谱震级的概念:认为按某一震源参考球的平均值,具有相同强度的 P 波(或 S波)位移谱的地震,则震级相等.这种震级标度有以下优点:(1)它是绝对力学标度,可以把世界上各台网的震级统一起来;(2)物理意义明确,能反映地震大小.对任何大小地震都有定义,无饱和问题,对慢地震也有定义;(3)能和以前使用的震级衔接起来;(4)对位移计地震仪来说,测量方便,误差小.
