- Kilauea, Hawaii: The most active volcano on the globe
Kilauea remains the undisputed champion of continuous activity. Located in the Hawaii Volcanoes National Park, it has erupted almost incessantly since 1983, with short breaks. In 2026, lava flows continue to reshape the island’s terrain, being monitored non-stop via satellite. Its effusive activity (lava flows) is essential for understanding how volcanic islands grow.
- Mount Etna, Italy: “The Lighthouse of the Mediterranean”
Europe’s highest and most active volcano, Etna, offers constant pyrotechnic displays. In recent years alone, the volcano has recorded dozens of paroxysmal episodes, shooting lava fountains hundreds of meters high. Its ash frequently affects air traffic in Catania, demonstrating the direct economic impact of volcanic activity.
- Merapi, Indonesia: “Mountain of fire”
Merapi is considered one of the most dangerous volcanoes in the world due to the population density surrounding it and the pyroclastic flows (clouds of superheated gas and rock) that descend its slopes at staggering speeds.
In March 2026, Indonesian authorities maintained a high alert level due to the instability of the lava dome.
- Fagradalsfjall, Iceland: A new era of arctic volcanism
After eight centuries of silence, the Reykjanes Peninsula has become a global hotspot. Eruptions starting in 2021 and continuing through new fissures in 2024, 2025, and 2026 have transformed the area into a living laboratory for geologists.
Iceland remains the region where tectonic plates pull apart before our eyes, fueling these spectacular eruptions.
