How these numbers were counted

Counts include every earthquake of magnitude 1.0 and above that USGS located within 100 km of Seattle. The search is a circle of 100 km around the centre of Seattle, so everything listed is genuinely within that distance. Full method, including why counts from different places are not comparable.
