How big is the volcano closest to Michigan?

Answer 1

The closest significant volcano to Michigan is the Fissure Vent of the Mid-Continent Rift, located in the Lake Superior region. However, it is not an active volcano but rather a geological feature associated with ancient volcanic activity. The region does not have any large active volcanoes; the nearest active volcanoes are located much farther away, primarily in the western United States, like those in the Cascade Range. Thus, Michigan itself is not near any sizable active volcanic formations.
