The United States boasts a diverse and geologically active volcanic landscape, extending from the Pacific coast to the island chains of Hawaii and Alaska. This widespread volcanism stems from various tectonic settings, including subduction zones, continental rifting, and the presence of a mantle hotspot beneath the Hawaiian Islands. The American landscape includes towering stratovolcanoes, sprawling calderas, shield volcanoes, and vast fields of cinder cones.

The Cascade Range, stretching from northern California to British Columbia, is a product of the Juan de Fuca Plate subducting beneath the North American Plate. Iconic peaks like Mount Rainier, Mount St. Helens, and Mount Hood dominate this volcanic arc with their potential for explosive eruptions. Alaska, another hotspot of volcanism, is home to numerous stratovolcanoes and calderas along the Aleutian Arc. The Hawaiian Islands, fueled by a mantle plume, feature the active shield volcanoes Mauna Loa and Kilauea, renowned for their spectacular lava flows.
