预测大地震概率的数学原理

Mathematical principles of predicting the probabilities of large earthquakes

V. M. Ghertzik

摘要:

一种多分量随机过程,用作时空地震预测问题的模型;如果表征地震活动性史前史的预报值已知,这使我们能够对大地震的条件概率进行一致的估计。我们介绍了评估预测效率的工具,包括一个单独的确定效率的“时间预测”和“位置预测”:广义相关系数和密度的信息增益。我们提出了一种技术,用于测试的预测,以决定是否可以拒绝没有预测的假设。

英文摘要:

A multicomponent random process used as a model for the problem of space-time earthquake prediction; this allows us to develop consistent estimation for conditional probabilities of large earthquakes if the values of the predictor characterizing the seismicity prehistory are known. We introduce tools for assessing prediction efficiency, including a separate determination of efficiency for "time prediction" and "location prediction": a generalized correlation coefficient and the density of information gain. We suggest a technique for testing the predictor to decide whether the hypothesis of no prediction can be rejected.
