Years8
  • The Blackfoot Volcanic Field is a relatively young (less than ~1 million years old) volcanic field located around Blackfoot Reservoir, north of Soda Springs, Idaho. (usgs.gov)
  • This is a giant horseshoe-shaped depression, formed in the last 13,000 years. (euronews.com)
  • Mt Etna's eruptions have been documented for more than 2,000 years when it was still part of Ancient Rome. (euronews.com)
  • The samples provided conclusive evidence of the crater, as they contained fragments of volcanic rock and ash that were dated to be over 300 million years old. (makingstridessecondlife.org)
  • Over millions of years, volcanic eruptions have not only built the Hawaiian archipelago, they continually transform its landscape. (nationalgeographic.com)
  • The plate tectonic "dance of the continents" tore North America away from Australia 800 million years ago. (techandsciencepost.com)
  • But great progress has been made because of the lessons learned over many years at Kilauea volcano in Hawaii, and applied and modified at Mt. St. Helens before and during in eruption sequence in the 1980s. (studi.lt)
  • They persist for about 15,000 years on average and are typically 4° to 5°C warmer than the preceding glacial period, with the difference much larger at the poles than at the equator. (wattsupwiththat.com)
Tuff3
  • Here we use Bayesian statistical analysis and inverse thermal history modelling of feldspar argon-argon and zircon uranium-thorium/helium ages to investigate resurgence after the 74-thousand-year-old Youngest Toba Tuff eruption. (nature.com)
  • These eruptions often produce airborne ash which falls to the ground and fuses together into a rock called a tuff-deposits that can be found today exposed at the surface along the edges of the Eastern Snake River Plain. (usgs.gov)
  • The high point on the island, Monte Epomeo, is a volcanic horst composed of the Green Tuff ignimbrite deposit that was submerged after its eruption and then uplifted. (si.edu)

Processes3
  • By studying these layers, scientists can gain valuable insights into the volcano's eruption history and the processes that have shaped the landscape over time. (hawaiistar.com)
  • Due to its high resolution the new Digital Terrain Model of the Stromboli Island gives interesting information about the submerged structure of the volcano, particularly about the volcano-tectonic and gravitational processes involving the submarine flanks of the edifice. (springeropen.com)
  • Our results emphasized the response and recovery processes of VNCU to volcanic eruptions without the strong anthropogenic forcings, while the influence mechanisms of natural forcing on VNCU should receive more attention. (bvsalud.org)
Scientists3
  • Scientists revealed to MailOnline how big this eruption could be and whether it will rival Eyjafjallajokull , which saw 50,000 flights cancelled and 8 million passengers affected. (newsfeeds.media)
  • Amidst this deepened occupation of the landscape and its increasing vulnerability, scientists began to ask: Can we predict eruptions? (fkawdw.nl)
  • Previously, scientists, engineers, and explorers had been primarily concerned with what happened during eruptions: the ash, how lava moved, what it looked like, what lived on their flanks. (fkawdw.nl)
