Good question, lana16. The answer is yes, we can, sort of, kind of, but not very well. There are many different ways in which scientists have attempted to predict earthquakes, but all of them are not very reliable. Some of the methods include studying animal activity, tidal forces, patterns of previous quakes, and more. One particular method that did actually help China to evacuate most of the population before the 1975 Haicheng earthquake was the foreshock method. Basically, before a large quake occurs, several small ones may come before it. The only problem with this method is that only 50% of large quakes display these foreshocks, and only 5-10% of small quakes actually are foreshocks. Because of this, it is possible to have many false warnings before an actual large quake comes around. Unfortunately, however, there is really no method that is very accurate.
Hope this helps!
We can predict locations quite well. Our ability to predict times of earthquakes is quite limited, and is mostly a matter of probabilities.
