The Northern Appalachians Seismic Zone is an active seismic zone in the Appalachian Mountains of eastern North America, extending from New Brunswick southwards into New England and Boston. [1] Both the seismic zone and the resultant Appalachian Mountains were created by the collision of two tectonic plates about 440–480 million years ago during the middle Ordovician Period. [2]
