Potentially active volcanoes in the United States exist mainly in Hawaii, Alaska and the Pacific Northwest. When pressure builds up within a volcano’s molten rock, it has the potential to erupt, sending forth lava flows, poisonous gases and flying rock and ash that can sometimes travel hundreds of miles downwind.
