The geography of Indonesia is dominated by volcanoes that are formed due to subduction zones between the Eurasian plate and the Indo-Australian plate. Some of the volcanoes are notable for their eruptions, for instance, Krakatau for its global effects in 1883,[1] Lake Toba for its supervolcanic eruption estimated to have occurred 74,000 Before Present which was responsible for six years of volcanic winter,[2] and Mount Tambora for the most violent eruption in recorded history in 1815.[3]

Volcanoes in Indonesia are a part of the Pacific Ring of Fire. The 150 entries in the list below are grouped into six geographical regions, four of which belong to the volcanoes of the Sunda Arc trench system. The remaining two groups are volcanoes of Halmahera, including its surrounding volcanic islands, and volcanoes of Sulawesi and the Sangihe Islands. The latter group is in one volcanic arc together with the Philippine volcanoes.
The most active volcanoes are Mt Semeru and Merapi on Java island which have been responsible for thousands of deaths in the region. Since AD 1000, Kelut has erupted more than 30 times, of which the largest eruption was at scale 5 on the Volcanic Explosivity Index (VEI),[4] while Merapi has erupted more than 80 times.[5] The International Association of Volcanology and Chemistry of the Earth’s Interior has named Merapi as a Decade Volcano since 1995 because of its high volcanic activity.
Type of Volcanoes Status in Indonesia
Level 1 = Aktif Normal (Green)
Monitoring of visual, seismicity and other volcanic event do not indicate changes. No eruption in foreseeable future.
Level 2 = Waspada (Yellow)
Increasing activity of seismicity and other volcanic events, and visual changes around the crater. Magmatic, tectonic or hydrothermal disturbance, no eruption imminent.
Level 3 = Siaga (Orange)
Intensively increasing of seismicity with supported by other volcanic monitoring, obvious changes of visual observation and crater. based on observation data analysis, the activity will be followed by main eruption. If trend of increasing unrest continues, eruption possible within 2 weeks.
Level 4 = Awas (Red)
Following the main eruption, the initial eruption begin to occur as ash and vapor. Based on observation data analysis, the activity will be followed by main eruption. Eruption possible within 24 hours.
Lesser Sunda Islands
The Lesser Sunda Islands is a small archipelago which, from west to east, consists of Bali, Lombok, Sumbawa, Flores, Sumba and the Timor islands; all are located at the edge of the Australian continental shelf. Volcanoes in the area are formed because of oceanic crusts and the movement of the shelf itself.[19] Some volcanoes completely form an island, for instance, the Sangeang Api island. Mount Tambora, on Sumbawa island, erupted on 5 April 1815, with a scale 7 on the VEI and is considered the most violent eruption in recorded history.
