Mount Sinabung has been long active and endanger people living in the vicinity. Due to its activity, inhabitants of the village must leave their house to evacuation area.
Visiting Berastagi, you can see this volcano erupts ash, almost everyday. This becomes very popular view among travelers. I went closer to the slope of Mt Sinabung, Berastepu village, where the ash can be seen destroyed the plants on the slope and many houses were abandoned because of the volcano. I find it very sad, seeing houses, churches and schools left and damaged.
Until today, villagers are not allowed to return to their house, as Mount Sinabung activity has not back down. Even this August, the activity raised, the volcano erupts 4.5 km ash.
Mt Sinabung had slept for 1,200 years, and then in 2013 it starts active. According to Matteo Lupi and Stephen Miller, the volcano activity might have been triggered by quake in Nias in 2005 and Mentawai Enggano quake in 12 September 2007.
For me it was kind of a bit nervous visiting the Red Zone (Zona Merah) where people may not live. However farmers work in the red zone in the day time. They plants cabbage and potatoes on the fertile soil.
