First 5 events reported only at either S =Stamford or D =Danbury, CT
* seismic data re-read by Sykes (1986) in determining epicenter
depth, h, rounded to nearest km, study area 40.0 to 42.0 N, 73.5 to 75.5 W
Very small aftershocks often are omitted from this list
? In rightmost column indicates questionable earthquake
ln(area) = natural log of area; MM =maximum intensity; m(MM) =magnitude from MM;
m(Lg) =magnitude from Lg; n(Lg) =number Lg measurements
