I hear that in Louisville, KY they felt it (Where I used to live)... A 5.4 isn't that bad, BUT... if its a precursor event? I hope not...
The Louisville newspaper the
Courier Journal said experts believe in 50 years (this was in 1989) the area will have an 8.0... That fault has been really quiet for 100 years now...
Anyway, anyone feel it? Wouldn't wanna be in the St. Louis Arch during one of those!
