Dear Scott,
Where is the closest hot-spot volcano to California?
And how many active volcanoes are on land?
Matt
Dear Matt,
Yellowstone is the closest hot-spot volcano to California. To learn more
visit the lesson on Hot Spots
and Mantle Plumes and the
information about Yellowstone
National Park.
There are about 1500 active volcanoes. Most of them are on land.
