Throughout Earth’s history, there have undoubtedly been millions of active volcanoes. There have been around 1500 active volcanoes on land in the last 10,000 years, but the number of subsea volcanoes is unclear. Around 20 volcanoes erupt at any given moment. Volcanoes that have erupted at least once in the last 10,000 years are considered active. A potentially active volcano may be erupting or dormant.
Volcanoes in Indonesia
Indonesia has the most active volcanoes in the world and is part of the Pacific Ring of Fire. The Ring of Fire comprises 452 volcanoes, and it has more than 75% of the active and dormant volcanoes worldwide.
There are 147 volcanoes in Indonesia, 129 of which are active. Sumatra (67 volcanoes), West Java (35 volcanoes), Sulawesi & Sangihe Islands (21 volcanoes), Halmahera (16 volcanoes), Flores (16 volcanoes), East Java (15 volcanoes), Central Java (12 volcanoes), Bali, and the Lesser Sunda Islands are all home to volcanoes.

- Mount Merapi is Indonesia’s most active volcano, and it has erupted on a regular basis since 1548. It is a high-risk volcano that is constantly watched by volcanologists.
- Indonesia, after the United States, is the world’s second-largest geothermal power generator. Volcanic geology in Indonesia has led to an increase in the use of geothermal power, which provides a substantial source of renewable energy.
