We're waiting to see if Mount St. Helens will erupt again in Washington state, but we never hear about volcanic activity on the East Coast of the U.S. There's a scientific reason for this.
Sally Harris writes that the kinds of geological conditions there don't support volcanic activity. Geoscientist R.J. Tracy says, "The active margin of North America is its western margin, and only the northwestern segment of it currently has the right conditions to produce volcanoes like Mount St. Helens. The interior of North America and the East coast lie far from any currently active plate boundaries and therefore are not locales where volcanism can occur."
At least one of the following conditions must be present for volcanic activity: "Divergent margins," which are places where the Earth's plates move apart; "Convergent margins," where the Earth's plates collide and one dips below the other forming a volcanic arc that may become active; or "Hot spots" in the Earth's mantle.
There is evidence from rocks in Virginia that volcanoes erupted in the area about 200 million years ago
I was just researching this, and there are Volcanoes back there, they are just much older than the ones out west. There is a range of eroded volcanoes in N.H., a Volcanic outcropping in N.J., and I think it's Birmingham, AL. that sits right atop an ancient volcano. Also I've rea that the Yellowstone hot spot used to be under Ga.

Where will you NOT find volcanoes?
kansas, Michigan, and Illinois
What tectonic plates were involved in the eruption of the Michigan ice volcanoes?
None. The "ice volcanoes" on Lake Michigan were not true volcanoes. They formed as a result of waves crashing into ice on the lake and fountaining spray thtough holes. Some of this water froze around the hole, forming something that superficially resmbled a volcano.
Are shield volcanoes and volcanoes the same?
Not necessarily. Shield volcanoes are volcanoes, but not all volcanoes are shield volcanoes.
What type of vocanoes are there?
composite volcanoes shield volcanoes cinder cone volcanoes spatter cone volcanoes complex volcanoes
What are three types of volcanoes?
Three types of volcanoes are Cinder Cone Volcanoes, Shield Volcanoes and Composite Volcanoes.

composite volcanoes shield volcanoes cinder cone volcanoes spatter cone volcanoes complex volcanoes
What are the two type of volcanoes?
there are three and they are Active Volcanoes, Dormant Volcanoes, and Extinct Volcanoes.
Do volcanoes need lava to be known as actual volcanoes?
No, volcanoes do not need lava to be volcanoes.
What are three types of volcanoes?
Three types of volcanoes are Cinder Cone Volcanoes, Shield Volcanoes and Composite Volcanoes.
What 2 types of volcanoes are there?
There are three. From smallest to largest, they are: Cinder Cones, Composite Volcanoes (also called Strata Volcanoes), and then Shield Volcanoes.
Are there any kind of volcanos?
There are three different types of volcanoes. The types of volcanoes are shield volcanoes, dome volcanoes, and also composite volcanoes.
What is the difference between Compare volcanoes that form on land with volcanoes that form in the ocean.?
Land Volcanoes eat lamas and underwater volcanoes eat camals
What do volcanoes have?
Volcanoes have magma.
