The distinction between extinct and dormant volcanoes is quite difficult. Blue Flames and a Blue Acid Lake. Dormant volcanoes do still erupt from time to time, however, sometimes with devastating results for people who thought the volcano was completely extinct. As molten rock, called magma, pushes up through Earth’s mantle, it can collect in underground pockets in the planet’s crust called magma chambers.
