Would it be wise to monitor real time human activity to anticipate earthquakes?
If you have no prior information that event B depends on event A, it's a logical error to claim event A causes event B just because you find they are correlated.

Let's say you collect a large data set of how people use their computer-mouse, and show that there is some change in a statistic of this data preceding an earthquake. That cannot not prove that the anticipation of an earthquake is causing people to behave differently, because the data will always correlate just as well with some other unrelated event C (such as a swing in the stock-market.)
