Marapi

Since 2011, the volcano has been at the second level of a four-tier alert system set up by the Volcanological Survey of Indonesia. Predicting the volcano's behavior is described as difficult as the source of its sudden eruptions are shallow and near its peak, while its eruptions are not caused by a deep movement of magma that can be detected as volcanic earthquakes on seismic monitors. Nevertheless, there are about 1,400 people living on its slopes in the villages of Rubai and Gobah Cumantiang, about 5 to 6 kilometers from the summit.
