A still of the lava fountain from the livestreamed video. (USGS)Kīlauea, known as one of the world’s most active volcanoes, has erupted once again.Massive Lava Jet Reaches 1,000 FeetSince the end of last year, its crater has been intermittently shooting lava fountains, and on May 25, a jet of molten rock soared an impressive 300...
Credit: PixabaySmall earthquakes beneath Alaska’s Mount Spurr suggest that the volcano may be nearing an eruption. Located about 3,370 meters (11,070 feet) above sea level, the mountain has experienced a surge in seismic activity recently, with thousands of minor earthquakes reported.Increased Chances of EruptionMatthew Haney, a volcano seismologist at the Alaska Volcano Observatory, informed...
The caldera of Zavaritskii volcanoOleg Dirksen/University of St. AndrewsA longstanding mystery about a year that effectively skipped summer appears to have been resolved. Researchers, using advanced ice core analysis, have determined that the dramatic cooling of 1831 resulted from a massive volcanic eruption in a remote region north of Japan.1831: A Year of Global...
Credit: PixabayAfter nearly 800 years of inactivity, volcanoes on Iceland's Reykjanes Peninsula are reawakening with increased intensity. Since 2021, eight eruptions have occurred, driven by a shallow magma reservoir approximately 10 kilometers wide and located just 9-12 kilometers beneath the surface, according to new research.Geologist Valentin Troll from Uppsala University in Sweden, who led...
Pyroclastic flow and clouds of volcanic ash as Krakatoa eruptsDepositphotosWhen a region finds itself covered in volcanic ash, it's usually not a positive development. However, researchers from the University of Barcelona have uncovered a unique set of beneficial characteristics in volcanic ash, rendering it remarkably valuable as an energy storage medium.We've discussed both incredibly...

A recent study from the U.S. Geological Survey shows that roughly 75% of the United States is at risk of harmful earthquakes, as the updated National Seismic Hazard Model indicates. Covering all 50 states, the model emphasizes heightened risks along the Atlantic Coast and in earthquake-prone areas like California and Alaska. This information is...
Hot spot detections. The maximum, unsaturated 4.8 μm (M-band) spectral radiances from 266 hot spots identified in Juno JIRAM data obtained from March 2017 to July 2022, using data from orbits PJ5 to PJ43 grouped by order of magnitude. The larger the symbol, the greater the 4.8 μm spectral radiance. This is an equal-area Mollweide projection...
Greetings to the newly formed Japanese island, whose name remains undisclosed. Credit: Japan's Maritime Self-Defense ForceIn late October, a remarkable natural event unfolded as an underwater eruption gave rise to a brand-new volcanic island along the coast of Japan. This intriguing phenomenon, marked by billowing smoke and gradual expansion, has captured the world's attention.Emergence...
