A closer look at the mechanics inside an active eruption. What you’re seeing is a burst of fragmented magma—tiny molten droplets called pyroclasts—being pushed upward by rapidly expanding volcanic gases. The dense, dark plume is a mix of ash, fine rock particles, and water vapor, lifted high as hotter material rises and cooler air rushes in around it. This frame captures the exact moment when pressure, temperature, and gas release combine to eject incandescent material into the air. | AstroNatur

LARGEST VOLCANIC ERUPTION Volcanoes are among the most powerful forces on Earth. The largest eruptions release massive amounts of magma, ash, and gases, reshaping landscapes and even altering global climate. Such eruptions can create giant calderas, darken the skies, and affect life far beyond their immediate surroundings. Studying these events helps geologists understand Earth’s dynamic processes and prepare for future natural hazards. Follow Geomark Geoscience Education for more fascinating ge
