The science of the “X-ray vision” that reveals the magma beneath Yellowstone
Yellowstone Caldera Chronicles is a weekly column written by scientists and collaborators of the Yellowstone Volcano Observatory. This week's contribution is from Scott K. Johnson, Science Communication Associate at EarthScope Consortium. Jeopardy is unique for its question-to-the-answer format, with contestants using a clue like “this animal starred in a 1975 Steven Spielberger film and can constantly regrow lost teeth” to correctly respond “what is a shark?” The geophysical techniques that allow us to image the magma beneath Yellowstone―as in a recent study that provided a view of multiple separate magma reservoirs― work similarly. These studies are often of great public
USGS Scientist Donya Frank-Gilchrist Participates in Science Diplomacy Workshop
Dr. Donya Frank-Gilchrist visited the National Academies of Sciences, Engineering and Medicine during the Science and Innovation Diplomacy Workshop, organized by the U.S. Global Change Research and the Inter-American Institute for Global Change Research. Dr. Donya Frank-Gilchrist of the USGS St. Petersburg Coastal and Marine Science Center (SPCMSC) was invited to participate in a science and innovation diplomacy workshop, organized by the U.S. Global Change Research Program and the Inter-American Institute for Global Change Research. The workshop was focused on Latin America and the Caribbean and approximately 30 persons participated from various countries across the region. The workshop included training
Announcement: Subduction Zone Science Workshop – January 10–11, 2023
Subduction zone cartoon showing major parts of a typical subduction zone. Workshop themes align with three USGS subduction zone science and hazard priorities (relevant to earthquakes, volcanoes, landslides, tsunami and cascading phenomena): new observations and models of subduction zone processes, quantification of natural hazards and risk, and forecasting and situational awareness. The meeting agenda includes keynotes, contributed short-format talks and posters (contributions noted on the registration form), and discussions focusing on critical needs, research priorities, and plans for a cross-discipline community of practice. Travel support is available for a limited number of early career participants and for USGS scientists. Reach out to
Volcano Watch — The Art and Science of Geologic Mapping
Volcano Watch is a weekly article and activity update written by U.S. Geological Survey Hawaiian Volcano Observatory scientists and affiliates. This week's article is by HVO geologist Drew Downs. Examples of Hawaii geologic maps. The lefthand map is a USGS Hawaiian Volcano Observatory map created on September 17, 2024, within hours of remote sensing (helicopter overflight) of the eruption that occurred from September 15–20, 2024. Several age ranges for lava flows of interest are noted by color changes, with those that erupted from 1790–2018 in purple (older lava flows are gray), those erupted on September 15 in pink, and those
