Of these, roughly 90 have erupted during the Holocene, with many characterized by at least one large explosive eruption. These large tephra-producing eruptions (LTPEs) generate orders of magnitude more erupted material than a “typical ...Earlier this month, Fukutokuoka-no-ba, a submarine volcano located about 1,125 kilometers (700 miles) southeast of Tokyo, Japan, began to erupt. Though apparently not explosive, the eruption created a steam plume that reached a height of about 1,000 meters (3,280 feet). Observation flights over the eruption site found the water strongly ...Webcam image showing the upper Southwest Rift Zone of Kīlauea volcano.

It is hard, abrasive, mildly corrosive, conducts electricity when wet, and does not dissolve in water. Volcanic gases are emitted from a volcanic vent before, during or after a volcanic eruption. The most abundant volcanic gases include water vapor (H2O), carbon dioxide (CO 2) and ...The USGS Astrogeology Science Center conducts research on planetary volcanology. Volcanism is a key part of the chemical and thermal evolution of planetary bodies, and volcanic eruptions are one of the fundamental processes that create and alter the surface of planetary bodies. We often study volcanoes on Earth in order to better …Kīlauea volcano is erupting. At approximately 4:44 a.m. HST on June 7, 2023, the USGS Hawaiian Volcano Observatory detected glow in Kīlauea summit webcam images indicating that an eruption has commenced within Halemaʻumaʻu crater in Kīlauea’s summit caldera, within Hawai‘i Volcanoes National Park.Hot springs and volcanic gases seep from the summit indicating a relatively young and still-hot system. Non-volcanic shedding of young volcanic rock and ash from Mount Shasta’s steep slopes occurs during heavy rainfall or glacial floods.
