测定地震波速比值的变化,作为地震予报工作的方法之一近年来国际间研究的较多,发展较快。但震前波速比出现异常,仅有几例,尚在探讨中。我队在科学院地球所工作的基础上,继续在临汾盆地进行波速比值的观测试验,方法是“联合法”。关于这种方法的予报效果,有待于时间和震例去验证,现在就这种方法的理论基础和问题谈谈看法。 In recent years, as one of the methods of earthquake prediction, there are more studies in the world and the development is faster. However, before the earthquake wave velocity ratio abnormalities, only a few cases, is still under discussion. Based on the work of the Earth Institute at the Academy of Sciences, our team continued to observe and test the wave velocity ratio in the Linfen basin by using the “joint law.” The effectiveness of this method of reporting needs to be verified by the time and the earthquake cases. Now we will talk about the theoretical basis and problems of this method.
