Thousands of people have fled Bali, Indonesia, since Mount Agung began to erupt on November 25. The volcano spewed ash and lava two and a half miles into the sky. On November 27, authorities expanded the danger zone around the volcano. They raised the danger alert to the highest level. Bali’s airport was briefly closed, stranding tourists.
Indonesia is in the Ring of Fire. That is a belt around the Pacific Ocean containing most of Earth’s active volcanoes. Mount Agung’s last big eruption was in 1963. But in September, volcanic activity increased. By press time, about 100,000 people had been asked to evacuate.
