connection between st lawrence rift and the old ramapo fault area? this is almost clear to me.

With the last 5.6 EQ in Quebec ( more then 100 aftershock over 2.0 and more happen each 2-3hours) the earthquake have reach far over illinois valley, hudson river, connecticut, missisipi northern part, new brunswick fault too..
all point to the NEW MADRID Fault ACTIVITY. expect more EQ from st lawrence rift the pression on the laurantian craton.

"Boston-Ottawa seismic zone" and the presumed activity of the Ramapo fault (an ancient geological fault in northern New Jersey and southeastern New York State).
runs from eastern Pennsylvania to the mid-Hudson Valley, passing within a mile or two northwest of Indian Point. The researchers found that this system is not so much a single fracture as a braid of smaller ones, where quakes emanate from a set of still ill-defined faults. East and south of the Ramapo zone—and possibly more significant in terms of hazard is a set of nearly parallel northwest-southeast faults.

The researchers found lately concrete evidence for one significant previously unknown structure: an active seismic zone running at least 25 miles from Stamford, Conn., to the Hudson Valley town of Peekskill, N.Y., where it passes less than a mile north of the Indian Point nuclear power plant. The Stamford-Peekskill line stands out sharply on the researchers' earthquake map.
