The term “dormant” can be tricky. Krakatoa was considered “extinct” or “long-dormant” by the people living near it in the 1800s because it hadn’t erupted for over 200 years. Its sudden awakening in 1883 proved how dangerous dormant volcanoes can be. Today, the site remains very active. In contrast, Stromboli and Mauna Loa are “constantly active,” and Chimborazo is “extinct” (it hasn’t erupted in over 1,000 years). Krakatoa serves as a reminder that “dormancy” is simply a quiet phase in the life of a very dangerous, active volcanic system.
