And that’s true we always get worried about the big one ! I guess we should pay more attention to small ones too ! But also… we don’t want to be scarred for each small earthquake we feel
Actually, it’s not that simple Magnitude is not a linear scale. Each magnitude level represents about 30 times more energy released. It thus takes 30 magnitude M3 to equal the energy released in a magnitude M4 earthquake !
It takes 900 magnitude M3 to equal a magnitude M5 … and 729 billion magnitude M3 to equal a single magnitude M9.
So yes, a small quake may temporarily ease stress on a fault line, however, it does not prevent a large temblor from happening
