Magma beneath long-dormant Mount Edgecumbe volcano in Southeast Alaska has been moving upward through Earth's crust, according to research the Alaska Volcano Observatory rapidly produced using a new method.

The Plinian eruption of Mount Vesuvius around 4,000 years ago -- 2,000 years before the one that buried the Roman city of Pompeii -- left a remarkably intact glimpse into Early Bronze Age village life in the Campania region of Southern Italy. The village offers a rare glimpse into the lives of the people who lived there, and the degree of preservation led the researchers to pinpoint the timing of the eruption, based on archaeobotanical record.

It isn't every day that we learn something that fundamentally changes how we understand our world. But for volcanologists across the globe, such a revelation has occurred.

New research reveals more about the magnitude of January eruption, as researchers call for better preparedness The eruption of the Hunga Tonga-Hunga Ha'apai volcano in January created an initial wave 90 meters high -- almost the height of the Statue of Liberty (93m). Tsunami expert calls for better warning systems to detect volcanic eruptions, saying systems are '30 years behind' comparable earthquake detection tools.

While funding is pumped into preventing low-probability scenarios such as asteroid collision, the far more likely threat of a large volcanic eruption is close to ignored -- despite much that could be done to reduce the risks, say researchers.

Researchers have discovered that super-eruptions occur when huge accumulations of magma deep in the Earth's crust, formed over millions of years, move rapidly to the surface disrupting pre-existing rock.

Aerosol particles in the atmosphere have a bigger impact on cloud cover -- but less effect on cloud brightness -- than previously thought, new research shows.

Computers can be trained to better detect distant nuclear detonations, chemical blasts and volcano eruptions by learning from artificial explosion signals, according to a new method.

Using data from the eruption of the underwater volcano near Tonga in 2022, researchers used disturbances in Earth's upper atmosphere to track the airwaves that cause tsunami. Their findings may lead to speedier predictions of these giant waves.

Researchers used a fiber optic cable on the ice cap of an Icelandic subglacial volcano to detect low-frequency volcanic tremor, suggesting this technology could be useful in monitoring other ice-covered volcano systems.

As it captivated people around the world, the January eruption of the Hunga Tonga-Hunga Ha'apai volcano gave scientists a once-in-a-lifetime chance to study how the atmosphere works, unlocking keys to better predict the weather and changing climate.

The eruption of the Hunga Tonga-Hunga Ha'apai submarine volcano in January 2022 was one of the most explosive volcanic events of the modern era, a new study has confirmed.

The recent Fagradalsfjall eruption in the southwest of Iceland has enthralled the whole world, including nature lovers and scientists alike. The eruption was especially important as it provided geologists with a unique opportunity to study magmas that were accumulated in a deep crustal magma reservoir but ultimately derived from the Earth's mantle (below 20 km).

Scientists say they have identified the exact mechanism responsible for the exceptional tsunami that spread quickly across the world after the colossal eruption of the Tonga volcano earlier this year.

In the fall of 2017, a team of geologists had just set up a new volcanic forecasting modeling program on the Blue Waters and iForge supercomputers. Simultaneously, another team was monitoring activity at the Sierra Negra volcano in the Galapagos Islands, Ecuador. The teams shared their insights and what happened next was the fortuitous forecast of the June 2018 Sierra Negra eruption five months before it occurred.

Before its big burst in 2018, Kilauea spent ten years erupting more gently. Research gives new insights into the volcano's longstanding lava lake, one feature of this eruption.

Using technology similar to night-vision goggles, researchers have developed a device that can generate electricity from thermal radiation.

New research modeling smoke from two recent megafires sets the stage for better forecasting of how emissions from these global-scale events will behave and impact temperatures. As huge wildfires become more common under climate change, increased attention has focused on the intensity and duration of their emissions, which rival those of some volcano eruptions.
