How these numbers were counted
Counts include every earthquake of magnitude 1.0 and above that USGS located in and around Massachusetts. The search is a latitude and longitude rectangle covering Massachusetts. No region is a rectangle, so events just outside the border can appear; each row shows the location text USGS published, which names the nearest town. Full method, including why counts from different places are not comparable.
