The last time New Madrid had a sequence eruption (1811-12) there were 18 quakes that were felt in Montreal. However, there was not any real damage or
anything. Most were just felt. About 3 of them (the biggest ones) knocked dishes and books off shelves in Montreal.
In the past, around 1400 AD, the New Madrid quake sequence magnitudes were a bit larger than in 1811-12, and around 900 AD, that sequence actually had
substantially larger magnitudes than the ones in 1811-12.
So, if you were in Montreal for example, and a really big New Madrid quake hit, you would probably not be in any danger, but you might have books and
shelves knocked down.
Hopefully this info helps.
