“Last eruption” is a catalogue record, not evidence of activity in progress.
Eruptions with fatalities, damage or high explosivity from the NOAA NCEI database of significant volcanic eruptions.
The Volcanic Explosivity Index (VEI) runs from 0 (effusive) to 8 (super-eruptive). Each step stands for roughly ten times the erupted mass.
Documented eruptions since 1500. Earlier centuries are recorded less completely, so a rise also reflects better observation.
603 events in the last 30 days within 50 km of a volcano in Indonesia.
Spatial proximity does not establish a volcanic origin. Many events in volcanic regions are tectonic.
What the volcanic landscape of Indonesia is made of and which tectonic setting it sits in.
Airports with scheduled service and nuclear power plant sites near a volcano in Indonesia.
No site from the included datasets lies within this radius.
This selection shows geographic proximity, not a hazard zone or confirmed impacts.
Short descriptions of the country's best-known volcanoes.
Semeru is the highest mountain on the Indonesian island of Java and an active volcano located in the province of East Java in a subduction zone, where the Indo-Australian Plate subducts under the Eurasian Plate. Semeru is 3,676 m tall at its peak, making it the third tallest volcano mountain in Indonesia after Kerinci and Rinjani.
Mount Merapi is an active stratovolcano located on the border between the province of Central Java and the Special Region of Yogyakarta, Indonesia. It is the most active volcano in Indonesia and has erupted regularly since 1548. It is located approximately 28 km (17 mi) north of Yogyakarta city which has a population of 2.4 million. Thousands of people live on the flanks of the volcano, with villages as high as 1,700 m (5,577 ft) above sea level.
Mount Sinabung is an active stratovolcano consisting of andesite and dacite in the Karo plateau of Karo Regency, North Sumatra, Indonesia, 40 kilometres (25 mi) from Lake Toba. Many old lava flows are on its flanks and the last known eruption, before recent times, occurred 1200 years before present, between 740 - 880 CE. Solfataric activities were last observed at the summit in 1912; recent documented events include an eruption in the early hours of 29 August 2010 and eruptions in September and November 2013, January, February and October 2014. The volcano has recently claimed the life of at least 23 people in a number of events since 2014. Between 2013 and 2014, the alert for a major event was increased with no significant activity. On 2 June 2015, the alert was again increased, and on 26 June 2015, at least 10,000 people were evacuated, fearing a major eruption. The long eruption of Mount Sinabung is similar to that of Mount Unzen in Japan, which erupted for five years after lying dormant for 400 years. A major eruption began on 10 August 2020.
Karangetang, also known as Api Siau is a volcano on the north side of Siau Island off the coast of Sulawesi, Indonesia. The island covers 160 km2, and had 46,459 inhabitants in mid 2023. It is one of the most active volcanoes in Indonesia, having erupted 41 times since 1675. A pyroclastic flow in 1997 killed three people. Karangetang is the tallest mountain in offshore North Sulawesi, at 1827 meters above sea level.
Mount Ile Lewotolok or Lewotolo, or Gunung Api Lewotolok, is a stratovolcano in the north-central part of the island of Lembata in the Province of East Nusa Tenggara in Indonesia. Its most recent eruption was in September 2026.
Mount Ibu is a stratovolcano at the north-west coast of Halmahera island, Indonesia. The summit is truncated and contains nested craters. The inner crater is 1 km (0.62 mi) wide and 400 m (1,312 ft) deep, while the outer is 1.2 km (0.75 mi) wide. A large parasitic cone is at the north-east of the summit and a smaller one at the south-west. The latter feeds a lava flow down the west flank. A group of maars are on the western and northern side of the volcano. Mount Ibu sits within the Pacific Ocean's "Ring of Fire" that has 127 active volcanoes.
