Are there any plate boundaries near Maryland?

Yes, the North American Plate and the Caribbean Plate boundary is located near Maryland. This boundary is a convergent boundary, meaning that the two plates are colliding with each other. The Caribbean Plate is moving eastward and is colliding with the North American Plate, which is moving westward. This collision is causing the Caribbean Plate to be subducted under the North American Plate. The subduction zone is located about 100 kilometers (62 miles) east of the coast of Maryland.
