Predict and guess the earthquake!

It is almost impossible to predict earthquakes. But in some cases it is possible, for example, if they are caused by reservoirs. This has been demonstrated, at least, in a region of India, around the Koyna reservoir. In May microcarías were produced and data were collected and a comprehensive study was announced (seismologists have forty years of experience) that the reservoir was going to produce an earthquake of 4th magnitude before fifteen days. And so it happened.
