The Hunga-Tonga-Hunga-Ha’apai volcano’s eruption in 2022 was the most significant in 30 years, sending ash high into the atmosphere and causing tsunamis across the Pacific….
Several Earth-observing satellites collected data during and after the potent blast. One of the most potent volcanic eruptions in decades has obliterated a small, uninhabited…
Eruptions create sulfuric acid clouds in the upper atmosphere and can cool the climate. Volcanic eruptions significantly influenced the collapse of Chinese dynasties over the…
The 2018 collapse of Indonesia’s Anak Krakatau volcano, which triggered a devastating tsunami, resulted from long-term geological processes rather than sudden magmatic changes. Researchers from…
Clouds parted for a glimpse of one of the most dangerous volcanoes on Earth, Mount Vesuvius, located near Naples, Italy. Mount Vesuvius, located 12 kilometers…
Satellites captured the intense volcanic activity on Isabela Island in the Galápagos, with the eruption starting late on January 6, 2022. Lava and ash clouds…
Hotspot temperatures vary more than previously thought, with some being much cooler, suggesting diverse origins and challenging traditional views on their formation. The hotspots that…
Flows of superheated ash and tephra mixed with rain to create destructive rivers of debris on the Indonesian volcano. Mount Semeru, the tallest and most…
The nearly 1,000-meter-tall volcano in the South Sandwich Islands frequently finds a way to put on a show. Mount Michael, an active stratovolcano in the…
