Mapped: All of the World’s Volcanic Eruptions in 2025

This was originally posted on our Voronoi app. Download the app for free on iOS or Android and discover incredible data-driven charts from a variety of trusted sources.

Key Takeaways
  • More than 70 volcanoes worldwide experienced eruptive activity in 2025, spanning every inhabited continent.
  • Many eruptions are long-running events, with several volcanoes active continuously for years or even decades.

    • In 2025, volcanic eruptions occurred across a wide range of tectonic settings, from explosive island arcs to submarine volcanoes hidden beneath the ocean surface.

    Some events lasted just days, while others continued multi-year or even multi-decade eruptive phases. This map visualizes every volcanic eruption recorded globally during last year.

    The data for this visualization comes from the Smithsonian Global Volcanism Program (GVP). It catalogs confirmed eruptive activity by volcano, location, eruption type, and duration, including eruptions that began before 2025 but remained active throughout the year.

    The Pacific Ring of Fire Remains the Most Active

    As expected, most eruptions in 2025 occurred along the Pacific Ring of Fire. This geologically active zone includes countries such as Indonesia, Japan, the Philippines, Papua New Guinea, New Zealand, Chile, Peru, Mexico, the United States, Russia, and several Pacific island nations.

    Countries such as Indonesia, Japan, the Philippines, and Russia recorded numerous active volcanoes. Indonesia alone hosted several long-running eruptions, including Merapi, Semeru, and Ibu. These regions sit atop converging tectonic plates, where magma generation and seismic activity are especially common.

    Long-Running Eruptions Dominate Global Activity

    Many of the volcanoes active in 2025 were not new eruptions but part of ongoing events that began years or even decades earlier.

    Stromboli in Italy has been erupting continuously since 1934, while Yasur in Vanuatu has remained active for centuries. Persistent lava lakes were also observed at volcanoes like Nyiragongo in the DR Congo and Masaya in Nicaragua.

    Not all eruptions occur near populated areas. Several submarine eruptions were recorded in 2025, including activity at Ahyi near the Northern Mariana Islands and along the East Pacific Rise.

    Remote volcanoes such as Erebus in Antarctica and Heard Island in the southern Indian Ocean also remained active. While these eruptions rarely threaten human settlements directly, they are crucial for understanding Earth’s internal processes and long-term volcanic behavior.
