Q: What is the probability that an earthquake is a foreshock to a larger earthquake?

问：一场地震是一场更大地震前震的概率有多大？

In California, that probability is about 6%. This means that there is about a 94% chance that any earthquake will NOT be a foreshock.

这意味着有大约94%的机会，一次地震不会成为另一场更大地震的前震。

So, if we can make low probability forecasts, short term (such as those currently based on foreshock and aftershock models) what can society do with them?

所以，如果我们能够做出某些低概率的预测、短期的预测〔如目前建立在前震或余震数学模型基础上的预测〕，社会可以用它们做什么？
