This seems like a very confused way of thinking about earthquakes.
In the past month, there were 4 earthquakes associated with the Juan del Fuca subduction. All were around Richter 2.5 and no one cared.
While I suppose it’s possible for a fault to produce small and large earthquakes both more often than in between, this strikes me as rather unlikely. Generally an analysis of earthquake risk should begin be deciding what magnitude earthquakes to care about, and then calculate probabilities.
(When we say that the Seattle area is particularly at-risk, that’s because architecture standards there contain very little earthquake-resilience. Which may not be relevant here. The actual fault line is among the less active on the west coast of North America.)
