Flights resume in Indonesia after two‑day suspension due to volcanic eruption

Indonesia, home to more than 120 active volcanoes, remains one of the world’s most volcanically active nations. The archipelago sits atop the Pacific “Ring of Fire,” a horseshoe-shaped belt of tectonic plate boundaries that encircles the Pacific Ocean and generates the majority of the planet’s earthquakes and volcanic eruptions. Because the Indo-Australian, Eurasian, Pacific and Philippine Sea plates converge beneath the region, magma readily reaches the surface, leading to frequent volcanic activity across the country’s islands.

The constant tectonic movement not only fuels eruptions but also poses ongoing risks to densely populated communities and critical infrastructure. National agencies maintain a network of monitoring stations to track seismic signals, gas emissions and ground deformation, enabling timely alerts and evacuation orders when necessary. Despite the hazards, Indonesia’s volcanic landscape contributes to fertile soils and geothermal energy potential, underscoring the dual challenge of managing natural threats while harnessing the benefits of its dynamic geology.
