Hi, Scott–
With no subduction zone nearby, PA is not a likely place to hunt for
volcanoes. But no place is totally safe from the arrival of a new hot spot –
the Hawaiian islands are volcanoes with no subduction zones nearby.
Earth magazine Jan. 1994 reports on a possible mantle plume (which would be how
a hot spot starts) rising off the western Canadian shore, but I have seen
nothing about PA there, and these things cannot be common (I think).
