 It's 
a myth that small quakes prevent large ones.

				The Mtyh: "Small earthquakes keep big ones from happening". Each magnitude level represents about 30 times more energy released. It takes 30 magnitude 3s to equal the energy released in a magnitude 4, 900 magnitude 3s to equal a magnitude 5 … and 729 billion magnitude 3s to equal a single magnitude 9. So while a small quake may temporarily ease stress on a fault line, it does not prevent a large temblor.
