A new study published in Science provides fresh insight into the geological processes that generate and sustain the enormous volcanic systems responsible for Earth’s largest eruptions. Scientists from the Institute of Geology and Geophysics of the Chinese Academy of Sciences developed a three-dimensional geodynamic model of western North America to investigate how magma forms beneath …
Mount Etna is one of the oldest and most active volcanoes in Europe, with a history stretching back over 500,000 years. Rising to about 3,400 meters on the island of Sicily, it erupts frequently—often several times each year—yet continues to puzzle scientists. Unlike most stratovolcanoes, which typically produce more silica-rich magma, Mount Etna is known …
For more than 100,000 years, the Methana volcano in Greece appeared inactive, showing no visible signs of eruptions such as lava flows, ash clouds, or explosions. Because of this long period of silence, it was widely assumed to be extinct. However, new research led by ETH Zurich and published in Science Advances reveals a very …
Supervolcanoes are capable of producing some of the most powerful natural events on Earth, known as supereruptions, which can eject more than 1,000 cubic kilometers of material into the atmosphere. These massive eruptions can alter global climate by blocking sunlight, lowering temperatures, and disrupting ecosystems for years. Because of these far-reaching consequences, scientists are working …
The Toba supereruption that occurred 74,000 years ago remains one of the most catastrophic natural events in the last 2.5 million years. Centered in present-day Indonesia, it released nearly 2,800 km³ of ash into the atmosphere—more than 10,000 times the amount produced by Mount St. Helens in 1980. Ash clouds would have darkened the sky …

Volcanic eruptions can range from minor disturbances to events that transform the planet. While small eruptions may merely inconvenience travelers or local residents, massive eruptions have had devastating effects on Earth’s ecosystems and history. For instance, a major eruption helped end the reign of the dinosaurs 66 million years ago, while another contributed to the …

A groundbreaking study has revealed that magma reservoirs persist beneath dormant volcanoes, challenging long-held assumptions about volcanic behavior. Using seismic wave imaging, researchers discovered extensive magma reservoirs beneath multiple volcanoes in the Cascade Range, including some that have been inactive for thousands of years. This finding suggests that volcanoes may remain primed for eruption much …
In 1815, Mount Tambora erupted in Indonesia, marking the most powerful volcanic event in recorded history. This cataclysmic event propelled vast quantities of sun-reflecting particles into the atmosphere, cooling the planet and triggering the infamous “year without a summer.” The resulting climatic disruptions caused global temperatures to plummet, crops to fail, and widespread famine, while …

Volcanoes are nature’s dramatic sculptors, known for their power to alter landscapes and ecosystems profoundly. Among the numerous volcanic events, the eruption of Mount Tambora in 1815 stands unparalleled in its global impact. This eruption, the most powerful in recorded history, drastically reshaped Mount Tambora itself, reducing its height by over 4,000 feet and creating …

Cataclysmic volcanic eruptions are rare but inevitable, and their potential global consequences make them a critical focus for preparedness. The 1815 eruption of Mount Tambora in Indonesia serves as a stark reminder of the devastation such events can cause. Tambora killed 90,000 people locally and led to severe global climate disruptions. The Northern Hemisphere experienced …
