Earthquake Forecasts are like probabilities but for shorter time windows, and this term is usually applied to aftershocks. After a large earthquake, there are aftershocks that are typically less frequent and smaller over time. 

Earthquake Probabilities describe the long-term chances that an earthquake of a certain magnitude will happen during a time window. Most earthquake probabilities are determined from the average rate of historical events.
