The eruption of huge volcanoes, supervolcanoes called, often cause dire consequences. It is fire and rain, shed for miles around the volcano itself, and global climate change caused by ingress of ash into the atmosphere. Fortunately, these volcanoes erupt on the average several times in 100,000 years. One of them, located on the territory of Yellowstone national Park, scientists say that, in all likelihood, ready for another eruption.

Researchers attribute the Indonesian archipelago to the part of the earth’s crust that are in the process of formation. While some of the island gradually, or suddenly appear from the depths of the sea, at a time when others are immersed in it. This is a consequence of frequent earthquakes, the effects of a large number of active volcanoes, as well as the growth of coral reefs. Such changes require frequent amended map of Indonesia.
