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？

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
