Might not be over. Sometimes they come in 3s.

 

And sometimes they come in 1s and sometimes they come in 4s. So? No matter how many there are someone can always say that it might not be over. There are often dozens, if not hundred, of aftershocks following a major quake.

What's your point? Are you trying to prove or disprove his point? He clearly said "sometimes". Sometimes they come in threes and, since he said sometimes, that implies he also says, sometimes they don't.

 

As a long time resident of California (and aficionado of seismology) , large earthquakes are followed by several months of so called "after shocks" which can be as severe as the first.

It depends on the specific area and some large events are followed by larger aftershocks while others have a gradually decaying pattern. According to Charles Richter's*** book Elementary Seismology, there are some areas in California where a large earthquake is often preceded by "foreshocks" and they provide a crude form of prediction of immanent risk.

*** The magnitude scale for earthquakes was actually developed as a joint venture between Richter and his associate Beno Gutenberg (the guy in my new avatar). There is still a controversy about why it isn't called the Richter-Gutenberg scale and how Richter gets all the public credit.
